Item Acesso aberto (Open Access) Análise comparativa hidroambiental das bacias do Una e da Estrada Nova, em Belém-PA, e suas implicações socioeconômicas(Universidade Federal do Pará, 2015-03-26) LEÃO, Eduardo Araujo de Souza; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626To evaluate the effectiveness of public interventions in relation to changing social dynamics and improve the quality of life of a population is necessary to the built and application of social indicators in monitoring public management, especially when dealing with large environmental interventions. As much as these indicators are mapped, the vast majority of environmental studies where these interventions occur, the government has dedicated itself or if it does not perform and monitor efficiently the behavior of these indicators over time. In Belém, the floods in urban areas pose a serious problem for most of the municipality, especially when involving densely occupied areas, at which generate considerable damage and often irreparable, even with losses of human lives. Flooding has been a problem during periods of frequent rainfall, both in the oldest areas of the city and consolidated, as in the areas of urban sprawl, a fact compounded by soil sealing, occupation of wetlands and removal of riparian vegetation, which hinders the infiltration rainwater. Due to these environmental factors and the inattention of government in providing social amenities and physical interventions in the area of the metropolis, populations that occupy the most vulnerable parts of the city of Belém, in general have a poor quality of life, as regards the issue of the environment in which they live. In order to comparatively evaluate two different realities and really consider whether public intervention was effective and efficient and from the same include as practical application of social indicators in monitoring the public administration, was used as case for this research performed by government intervention state in the basin of Una, where he was executed the deployment of Macro Drainage Basin of Una and services contemplated drinking water supply, sewerage, storm water drainage and road system, compared with the intervention of the municipal government to bowl Estrada Nova, running, with the deployment of these services. To develop the research, the study gathered data and information collected in the basin of Una and projected future scenarios for the basin of Estrada Nova, using the same indicators. These indicators in this study were also addressed and strengthened with a hydrogeological assessment of the two basins, the analysis of quality of surface and groundwater, consideration of the incidence of waterborne diseases, the vulnerability of aquifers, configured together in a GIS specifically built for it, with the aim of evaluating the criticality of spatialization basins and identify which areas need more attention or have the best results. The study demonstrated that the physical and socioeconomic study of the two basins are similar and after the intervention in the basin of Una, any kind of indicator was monitored with a view to demonstrate the effectiveness of the intervention. The study also showed that health indicators linked to waterborne (why the intervention was also made) chosen for monitoring before and after the intervention, have partially direct connections to the environmental quality of the basin, but many indicators not could be chosen by the lack of government data. The vulnerability of the aquifer top is also concern in some quarters, in that much of the population obtains its supplies from this aquifer, which has its recharge provided, in part, by draining channels of Belém, known holders of very bad quality indices its waters and can even be characterized as true open sewers. The drainage channels and creeks of Belém, are thus responsible for directing this excess sewage into the Bay of Guajará and river Guamá through interconnection with those that have physiographic elements. Because the city has much of its area located in quotas of up to 4 meters, which is also the average annual tidal amplitude regional, these areas are subject to flooding. By way of consequence throughout the upper aquifer is vulnerable to infiltration of contaminated water channels, which in times of floods are dammed increasing the residence time in them,. The research now being evaluated scenarios and presentation indicators, this reality, leaving open the need to be constructed and monitored indicators other than the act of evaluating the effectiveness of public intervention can be more consistent. Finally the study also notes that several indicators could not be considered in the study due to insufficient and the quality of data provided by the government.Item Acesso aberto (Open Access) Análise do custo da água virtual e a formação de valores: estudo de caso na comunidade Cristo Alves – Curuçá – PA(Universidade Federal do Pará, 2017) CEI, Joelson Carvalho; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Water is a strategic asset for the survival of mankind. Pressures from increased food production, the development of water-dependent energy sources, population growth and economic growth have boosted water consumption. Thus, the increasing demand for water and the limited possibilities to increase its supply impose new practices and management tools that promote the efficiency of water use in distribution, consumption, and the productive process and encourage the rationalization of its use. Thus, the concepts of water footprint and virtual water have been gaining prominence in the scientific scenario, given the challenge of developing water use management practices based on the promotion of water efficiency. These concepts act as indicators of the use and appropriation of water in the perspectives of production and consumption. In this context, this work aims to analyze the processes of measurement of the cost and export of virtual water by the production of orange in the community of Christ Alves in the municipality of Curuçá - Pará. The analysis will be based on the orange produced in the Christ community Alves, in the municipality of Curuçá, Northeastern region of Para. The data collection for the costs of water used in the planting and irrigation of the orange will be based on information extracted from the farmers by a semi-structured questionnaire in relation to knowledge about water resources. Scientific data from the water footprint and virtual water will be used to elaborate how these costs are measured.Item Acesso aberto (Open Access) Arcabouço geológico-geofísico da região nordeste do Estado do Pará(Universidade Federal do Pará, 2017) JORGE, Maurício Victor Elleres; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The northeastern region of the State of Pará presents great potential for the occurrence of groundwater resources. Two hydrogeological systems are present in it: Pirabas and Barreiras. From a gravimetric survey conducted in this research, associated to secondary data collected in academic works and state projects (SIAGAS-CPRM), it was possible to advance the understanding of the regional geometric arrangement that determines the spatial distribution of the sedimentary packages. Map and geological-geophysical profiles of the bouguer anomaly behavior are presented, necessary to support the presented spatial ordering. The geophysical signature of the gravity anomalies in the Bouguer anomaly map analysis revealed positive and negative regions, which are limited by gravimetric lineaments, mainly NW-SE direction. Among the structures generated, in this arrangement, stands the Graben of Bragança - Viseu, partially contained in the work area. The indication of depth presented in the gravimetric profiles, and in the constructive profiles of wells, reveal to us outstanding aspects of the geometry of the sedimentary package. The geometric model of the morphostructural configuration of uneven tectonic blocks, responsible for the regional structuring of the area and the definition of places more favorable to the encounter of the largest thicknesses of sediments, in which the mentioned hydrogeological systems are closed, is confirmed in the obtained results. Thus, the methodologies and techniques used in this work proved to be robust to understand the geological compartmentalization of the work area, with respect to the guide with a higher success rate, the location of wells, in terms of expected productivity. as an important tool for planning and managing water resources.Item Acesso aberto (Open Access) Contribuição ao conhecimento das formações Barreiras Pirabas utilizando-se ferramentas da análise estrutural com vistas à aplicação em hidrogeologia(Universidade Federal do Pará, 2016-10-17) SILVA, Larissa Silva e; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The existence of hydraulic connection between Barreiras and Pirabas aquifers systems in the northeast area of the State of Pará, more specifically in the metropolitan region of Belém - RMB has been raised, a few years ago, by different authors from the application of various analytical techniques. This work presents further contribution to this theme, that has been aggregated to the data and to the information obtained from the use of structural analysis tools, to understand the groundwater flow mechanism and recharge conditions, which takes place in area under consideration. The work was performed from the databases on existing wells in private and public agencies. The performed structural analysis considered the geometric-kinematic elements present in the mentioned water systems and it advanced in the knowledge of the tectonic processes that have led to the conformation of the geometric arrangement present in the area, considered essentially as neotectonic. It was found that the development of brittle tectonic structures, especially holes, printed on regional rocks that enclose the water systems, leading to spatial composition of morpho-structural blocks arrangements horsts and grabens limited preferably by the NE and SW discontinuities resulting from the interaction of normal faults with strike-slip faults. The boundaries of these blocks, always marked by failures allow the interconnection of the movement of water from aquifers of different spatial positions systems, sustained by the principle of communicating vessels, the elapsing the mixture of water contained in each one of them individually. So it is impossible to keep the model advocated by several authors in the literature of regional aquifer confinement. On the other hand, the development of potentiometric maps and flow in regions of sedimentary rocks, where it is called homogeneous media, as this case is of the RMB cannot be done without considering the structural analysis, geometry and kinematics, otherwise it would be misunderstood in the preparation of such results and mistaken hydrogeological interpretation. Thus, it is necessary to review the methodologies for the preparation of these important instruments in order to obtain more precise results on the flow mechanisms, recharge and discharge of water systems which has been developed and answered in this work.Item Acesso aberto (Open Access) Estudo tectono-sedimentar da Bacia de Jaibaras, na região entre as cidades de Pacujá e Jaibaras, noroeste do estado do Ceará(Universidade Federal do Pará, 1996-04-22) QUADROS, Marcos Luiz do Espírito Santo; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Studies carried out in southwestern portion of the Jaibaras Basin in the area of the 300 km², situated between the Pacujá and Jaibaras towns, northwest region of Ceará State, including geological mapping in 1:25,000 scale, faciologic, petrographic and structural analysis of the Pacujá and Aprazível formations, allowed a better visualization of spatial distribution of these units, as well as the characterization of their depositional environment, structural pattern and, at last to take considerations about the tectono-sedimentary evolution of the Jaibaras Basin. The Pacujá Formation is characterized by a folded and faulted volcanosedimentary sequence without fossils, made of rhythmic interlayers of fine arkosian sandstones to siltistones with pelites, occurring in tabular decimeter thick beds, laterally continuous, showing abrupt base and upward gradation to siltistones. The sandstones could be massive or stratified, showing planar lamination, micro-hummocky cross lamination, climbing wave -ripple cross lamination, locally parting lineation and convolute lamination. On the top of the sandstone beds occur symetrical and assymetrical wavy-ripples. Pelites show planar lamination and mudcracks. Interlayered with Pacujá Formation sediments occur volcanic and subvolcanic rocks (basalts, andesites, dacites and ryolites), at the form sills, dikes and flows, associated with volcaniclastic rocks, included on the Parapuí Suite. The environment of the Pacujá Formation was characterized as lacustrine with volcanism associated, subjected to storm-wave action, proved by the occurrence of microhummocky cross lamination.The rhythmics interlayering of sandstones and pelites characterizes tempestites cycles, usually incomplete. However, marine environment must be assoc iated, but unfortunately the field datas is insufficient to define this environments. In the Jaibaras Basin setting, Pacujá Formation represents the first deposicional pulse that extend from Neoproterozoic era to Cambrian period. This sedimentation occurred in an area wider than Jaibaras Basin out of their present boundaries. The Pacujá Formation shows a complex fold pattern, that resulted from superimposed folding, with geometric shapes similar to type 1 interference pattern - “domes and basins”, and kinks folds. This folding could be related to transpression in ductile -brittle regime, linked to the northest-southwest sinistral strike -slip system in the Eopaleozoic era, that caused a weak inversion of the Jaibaras Basin. The Aprazível Formation comprises a thin sedimentary sequence, faulted and tilted to southeastern on the whole, unconformably covering the Pacujá Formation. It is made of polymitic conglomerates, with clast-supported and matrix -supported framework, massive or stratified, with volcanic, gneiss, granite, rocks calcissilicatic, quartz, amphibolite, rhyolite, marble, mylonite, siltistone and sandstone clasts, varying in size from granules to boulders. The matrix is coarse to very coarse sandy arkosean, locally microconglomeratic. To a lesser proportion, occurs medium to very coarse grained arkosean sandstones, locally stratified, and intercalations of laterally continuos beds of arkosean sandstones and laminated pelites with mudcracks in surfaces of the beds. These sandstones show planar lamination, climbing-ripple cross lamination, and locally trough cross-bedding and convolute lamination. In the surface of sandstone beds, there are, occasionally, symetrical and assymetrical wave-ripples. The depositional environment of the Aprazível Formation was characterized as alluvial fan/plain, dominated by debris-flows and stream-flows, prograding distally over small lacustrine bodies. The tilting of the Aprazível Formation beds to southeastern, is a results from rotation of blocks, due to an extensional axis in the northwest-southeast direction, acting in Ordovician period, that controlled the deposition of Aprazível Formation in the area between Sobral-Pedro II and Café -Ipueiras shear zones. The Aprazível Formation represents the second and last depositional pulse that occurred in the Jaibaras Basin in the Ordovician period, in a more restrict depositional area, controled by Sobral-Pedro II e Café-Ipueiras shear zones. Its deposition occurred in a time interval between the post-Pacujá sequence and Meruoca Suite Granites, and pre-Serra Grande Group sequence of the Parnaiba Basin.Item Acesso aberto (Open Access) Estudos geológicos na faixa de alto grau de Cariré, noroeste do estado do Ceará(Universidade Federal do Pará, 1996-06-13) FERREIRA, Marcos Aurélio Araújo; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Item Acesso aberto (Open Access) Evolução geológica da região nordeste do estado do Pará com base em estudos estruturais e isotópicos de granitóides(Universidade Federal do Pará, 2001-07-04) PALHETA, Edney Smith de Moraes; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Item Acesso aberto (Open Access) Evolução geológica das seqüências do embasamento na porção sul do Cinturão Araguaia - Região de Paraíso do Tocantins(Universidade Federal do Pará, 2002-09-12) ARCANJO, Silvia Helena de Souza; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The basement rocks in the south segment of the Araguaia Belt, due to the scarcity of geochronological information, were firstly considered as of Archean age. This interpretation began to be reviewed after the geochronological investigations were carried out during the last decade, which showed an important contribution of geological processes of the Paleoproterozoic in the formation of those basement rocks. In this work an isotopic study was carried out on the basement sequences of the southern segments of the Araguaia Belt and its results were based on the single zircon Pb-evaporation technique (Pb-Pb in zircon) and the Sm-Nd (whole rock) systematic. These techniques were used in order to improve and reconstruct the geological evolution of this crustal segment where Rio do Coco Group, Rio dos Mangues Complex, and Serrote Granite occur, as well as Monte Santo Suite that also appear in this context. The geological processes identified for the region took place from the Archean through the Neoproterozoic Era. The first evidences from the archean source were obtained in some restricted orthoderivated bodies in the east sector of the mapped area in which the TDM ages varied between 3.25 and 2.78 Ga. In a clear way, the Archean occurs in the northwest portion of the studied area being represented by a metabasic rock belonged to the Rio do Coco Group (greenstone belt sequence), with 2.618 ± 14 Ma. This age is interpreted as the age of the extrusion of the volcanic protolith. They would represent the two crustal preterit segments found in the region. During the Paleoproterozoic the Rio dos Mangues Complex was constituted, representing the most expressive unit of the basement. Ortogneisses of the Rio dos Mangues Complex were dated and their Pb-Pb in zircon ages varied between 2.054 ± 4 Ma and 2.086 ± 16 Ma. They were formed from a mantelic and juvenile source, with a small crustal contribution and their TDM ages are between 2.35 e 2.21 Ga. The geological processes that marked this period, involved crustal shortening with the participation of collision and thrusting that induced partial fusion of some parts of the thickened crust. The results were the generation of some igneous bodies (1.85 and 1.82 Ga) and of the Serrote Granite (1.86 Ga). Although the emplacement of the Serrote Granite took place at the end of the Paleoproterozoic, it was developed from older sources (2.50 e 2.43 Ga) than those of the Rio dos Mangues Complex. So, The continental crust established, with rocks from different ages and sources may be projected to the east, far from the studied area, inside the context of the architecture from the Atlantic Super Continent, formed definitively at the end of the Paleoproterozoic. At the end of a period without tectonic registers (end of Mesoproterozoic) a new phase took place in the region marked by tafrogenetic processes as the appearing of alkaline and basic magmatism as well as depositional basins that show an extensive context along the whole area. One of these basins received the sediments that originated the Araguaia Belt Supracrustals, which, during its evaluative process, reach the proto-rifte stage. Far from here, at the north portion of Goiás Massif, this rifting process seemed to permit the constitution of an oceanic domain, that, by evolution and recycling, may have be formed the rocks of the Magmatic Arc of Goiás. At the worked area, this arc terrain could be only be predicted by the appearing of one tonalitic gneiss with the age of 840 Ma and TDM model ages of 1.83 Ga. The effects of this tafrogenetic processes, from which the most important evidences are sienitic gneisses, found at Monte Santo Suit, with 1.051 ± 17 Ma, are related to the fission processes in the whole world which made the break up of the Rodinia Super Continent possible. The protolith of this suit were also been formed during the Mesoproterozoic as they can be seen in the TDM model age between 1.49 e 1.70 Ga. Finally, passing to the Neoproterozoic, through the inversion in the geodinamic conditions, processes of horizontal shortening again took place in the region, with the participation of crustal thickening as well as distinct volumetric and spatial fusions that may have generated the Matança and Santa Luzia Granites. The last one found inside the domain of Araguaia Belt. The Araguaia Belt was built from this tectonic motion, and has registers of past structural formations, also present in the older litostructural groups. The mass tectonic transport in the Amazonian Craton way might have occurred, resulting in the actual architecture found nowadays in the form of imbricated slices.Item Acesso aberto (Open Access) Ferramentas multidisciplinares aplicadas à cartografia geológica: o exemplo da Folha Sobral – CE (SA-24-Y-D-IV)(Universidade Federal do Pará, 2009-10-20) SANTOS, Márcia Valadares dos; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The northwestern region of Ceará includes land belonging to areas Médio Coreaú and Central Ceará of Borborema Province. Studies in this region, which fits Sobral Sheet (SA. YD-24-IV) scale of 1:100,000, sought to contribute to the advancement of geological knowledge of the region and this was done initially to systematize data and pre-existing geological information from an extensive body of work carried out by IG / UFPA, since the 1980s. Digital images (Landsat-5/TM and SRTM) also had been used. About the image in digital format (Landsat) were applied techniques for enhancement, filtering, processing by principal components and IHS transformation, which helped supplement the results of visual interpretation. The airborne data Project Rio Acaraú 1974 were processed using the software Montaj Oasis, and was basically in the interpolation of data (125m), micro generation and the themes processed. For magnetic data, were generated images of the anomalous magnetic field, derived from the horizontal (dx and dy) and vertical (dz), amplitude of the horizontal gradient analytic signal amplitude and slope of the analytical signal. Data airborne gama-ray spectrometry was possible to generate images of the channels of K, U, Th and CT images and ternary (RGB and CMY). The interpretation of the products of remote sensing and airborne geophysics, geological mapping associated with the scale of 1:100,000 Sheet Sobral allowed characterization of the pattern of Lito-structural region. Based on the objectives in this research and the methodology for its implementation were produced a geological map enriched with the contribution of geometric elements revealed by integrated analysis of all products considered, as well as other thematic maps. The work demonstrates the importance of using images from remote sensing and airborne integrated data digitally as important tools for geological mapping, making the maps produced richer and more reliable also providing information that may be available for fast since all products resulting from this work are in digital format.Item Acesso aberto (Open Access) Fundamentos para o gerenciamento integrado dos recursos hídricos na microbacia urbana do rio Maguari-Açu com vistas à sustentabilidade hidroambiental(Universidade Federal do Pará, 2012-08-24) SILVA, Valdinei Mendes da; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The city of Ananindeua, as part of the Belém Metropolitan Region - BMR, has received the negative impacts resulting from the disorderly occupation of territorial space. The natural conditions of the region have been ignored in this process of urban settlement, which is verified by analyzing the current status of surface and underground water resources, which are being rapidly degraded, because of the lack of interventions, that are primarily that guarantee government control of these impacts or the implementation of actions merely reproduce historical actions without success. The analysis of socioeconomic and hydro-environmental conditions demonstrated the hydro unsustainability of this region, as well as the existence of the various conflicts that refers specifically to water resources. In order to counter this situation, are presented basis for the integrated management of water resources in the urban watershed of the river "Maguari-Acu," which seek to reach this sustainability. Such basis were structured in five (05) actions: 1) Division of BMR in six (6) river basin, 2) Environmental zoning in River Basin of Maguari-Açu, 3) Management of soil sealing and runoff, 4) Strategies of social organization for the management of urban watersheds and 5) management of information from the integrated data base. To support such basis, future scenarios were developed, anchored in the legal framework and the existing technological apparatus, instruments sufficient for integrated actions between the government and society in general, making it possible to undertake the processing needed for the construction or reconstruction of cities from principles of sustainability.Item Acesso aberto (Open Access) Gestão Integrada das Águas em Rondônia(Universidade Federal do Pará, 2010-10-30) ZUFFO, Cátia Eliza; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626; 9626349043103626The situation of waters in Rondônia, the challenges for their management and, notably, for the social mobilization in their defense are the main focus of this thesis which was presented to the Geology and Geochemistry Post Graduation Program, of the Federal University of Pará, PPGG/UFPA. In tune with the Research Line in “ Hydric Resources Management”, from PPGG, the main objectives of the research were meant to: follow, register and analyze the process the policies implementation process and the system of management of hydric resources of Rondônia; contribute for the advance of this process through the accomplishment of studies on hydrogeology, underground and superficial water quality; put into practice some of the main pressupositions in water management in Brazil, at present time, which are the planning for hydrographic basin and the environmental education. The research was carried through based on the following hypothesis: the integrated water management in Rondônia, just like other states in the Amazon, is in a deficient or nonexisting situation idue to structural problems in the federative units administrative arrangement; the lack of management tools foreseen by Hydric Resource National Policies; the abundance and wastefulness culture; and, still, the execution of anthropic actions without the necessary research endorsement or consistent Waters data analysis, in their varied occurrence forms. Among the ways to go through the current situation are: management tool application by hydrographic basins, basin plan formulation and social mobilization valuation, getting to the constitution of collegiates, such as the hydrographic basin committees, important fori for debates in order to provide conditions to support sustainable regional development, what make it evident that integrated waters management depends on technical-scientific knowledge, administrative structure, compatible legislation and society mobilization to take good care of them.

The aim of this work is to offer information about these aquifers units thorough using data from geology, geometry and cinematic, hydrogeology and morph tectonic, to comprehend the evolution of these units in space and time. Databank used in this work was obtained from: (1) field data; (2) information of well drilling; (3) topographic maps in scal1 1:100,000; (4) Landsat 7 images; (5) SRTM – Shuttle Radar Topographic Mission; and (6) GIS – Geographic Information System of RMB, Guajará and Marajó Bay. Softwares SPRING, Arc View and Global Mapper were used to process and treatment of data and images. Two main scales were used in this study: (1) a regional scale 1:100,000 evolving maps of Belém, Acará and Abaetetuba giving a total of 10,635 km2; and (2) a semi detail scale 1:25,000 adjusted at RMB with total of 1, 929 km2. Morph tectonic analysis showed three geomorphologic domains: Fluvial Plain Terrain, Terrain of Hills and Terrain of Small Mountains. The directions of topographic elements of terrain are compatible with the directions of the drainage net. The analysis of drainage net gave five main basin domains: (1) Coastal; (2) Marapanim River; (3) Guamá River; (4) Acará-Moju River; and (5) Pará River. Thorough this analysis was identified and defined neotectonic elements represented for lineaments from each hydrographic basin, with general directions NE-SW, NW-SE and NNE-SSW in regional scale. The RMB shows main directions in NE-SW and NW-SE with secondary trends WNW-ESE. Using projection and extension of lineaments presents in RMB, was possible to draw a two-dimensional model, which form three-dimensional blocks. Were defined two kinds of sectors based on distinct aspects of blocks. Sector I is located in southeast and Sector II is in northeast portion of RMB. There are kinematics variations in these two sectors. Sector I has dextral moving with stretching direction NW-SE and normal faults NE-SW. In the Sector II the cinematic is sinistral with stretching direction NW-SE and normal faults NE-SW associated. 4 Correlation between water wells located in different blocks proved that geologic layers present in both blocks have distinct attitudes, probably influenced by neotectonic processes. In Sector I, the gradient is moderate 1/180 m/m in the other hand Sector II has gradient 5x bigger 1/30 m/m. The different values on gradient suggest that Sector I and II are distinct with regarding to the slope of layers. With treatment integrated of information obtained was possible to establish the stretching direction for Pirabas-Barreiras Basin in NW-SE. Normal faults related to the development of basin have trends NE-SW. These structures are potential surfaces of low pressure, being favorable places to recharging of aquifers intercepted by its. So it is necessary to be worried about the possibility of pollution in these aquifers by human activity in these places of recharge. Since the recharge areas are exposed to urban or agricultural purposes.Item Acesso aberto (Open Access) Neotectônica e estruturação dos sistemas hidrogeológicos da região de Castanhal/Pa(Universidade Federal do Pará, 2008-05-13) BANDEIRA, Iris Celeste Nascimento; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The morphstructural and hydrogeological studies done in two distinct scales, 1:100,000 and 1:25,000, in Castanhal City (PA), the advance on the understanding of the relation between geometric elements of hydrogeological systems and structural elements related to neotectonic events as a base to determine, among other aspects, potential recharge areas of these systems, was allowed. The morphstructural study supported by collected geophysical data showed that the area has a structural control related to a neotectonic pulse responsible for the reactivation of NW-SE-, NE-SW, NS and EW direction failures, which caused anomalies and changes in drainage patterns, and conditioned the establishment of terrain units where river plains, pediplanizadas hills and top-flattened hills jut out. These failures can become compatible in a system of efforts, which generated a geometric formation characterized by tectonic blocks limited by such failures, as well as a kinematic framework of dextral configuration, where in an explicit way extension failures were formed in the NW-SE direction, consolidating important flumes for the recharge of hydrogeological systems. The area is composed of three hydrogeological systems: Superior, characterized as free and found at depths from 2 to 8m; Barreiras varying from free and semiconfined and found from 20m depth, and Pirabas characterized as confined and found at depths from 90 to 120m. These systems present variable depths related to the displacement caused by neotectonics failures. From the confined hydrogeologics systems (Pirabas) to the semi-confined ones (Barreiras) are being largely recharged in the area of Castanhal by natural flumes which are the areas of extension failures and fractures of NW – SE direction. The recharging of the free hydrogeological systems (Superior and Barreiras) occurs by direct precipitation from the rain water in the central-west portion of the study area, in other words, near Couro do Curió river and in the northeast portion near Defunto river.Item Acesso aberto (Open Access) Planos de sistemas aqüíferos como fundamento legal para a gestão de recursos hídricos(Universidade Federal do Pará, 2010-07-14) GUTIERREZ, Lucy Anne Cardoso Lobão; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626; 9626349043103626The evaluation of self supply conditions in RMB, especially in 25 districts, which present consolidated and available information, bespoke the need of improving the management of groundwater resources in the state. In order to achieve that, the elaboration of the Water Systems Plans as a legal fundament for the management of water resources in the State of Pará, especially in RMB. The information and data gathered showed that the public water supply system presents some deficit, mostly due to absence of the public water supply network in many areas; inefficiency or absence of plans to extend this network; need of improvement and adequacy for the existing network; low availability of goods acquisition to the general improvement of the system; the high index of loss verified; and so on. Because of this the number of users has increased, particularly in the residential sector, which uses the tubular wells for self supply, almost ever completed in the water systems Pós-Barreiras and Barreiras. This scenario is observed, mainly in the districts having the most of buildings, such as Nazaré, Reduto, Umarizal and São Braz, which respectively present (62,9%), (49,2%), (31,8%), and (33,3%) of the residential economies provided by private wells for self supply. These aquifers demonstrate moderate to high vulnerability, whereas the available data of their water quality reveal high nitrate indexes probably caused by almost entire absence of sewage collection and treatment systems. A survey and an analysis about federal and state laws which are relevant to the water resources were also made for planning the model, observing that this law is much more advanced for superficial water. The settlement of future scenarios, from the methodology described by Michel Goodet, brought the linkage between management and planning of superficial and ground water, in view of the fact that in the national model, the territory for the management of the water is the drainage basin. To allow that planning groundwater does not occur in a disintegrated way in the scope of drainage basins nor is totally attached to the start of superficial water management, a model of groundwater planning and management is proposed to the State of Pará. According to this model, the aquifer systems planning could be done through Aquifer Systems Plans, under the responsibility and coordination of the State. To the definition of elaboration and approval of these Plans, it is suggested the creation of Aquifer Systems Committees to be coordinated by the organ of the State for Water Resources, which will incorporate the imperative participation of users, representatives of the counties that are surrounded by overlying drainage basins to these aquifer systems, as well as the civil society organized, a new paradigm of operation for a contemporaneous society.Item Acesso aberto (Open Access) Uso de ferramentas multidisciplinares na avaliação de vulnerabilidade e risco a subsidência no meio cárstico na cidade de Castanhal, Nordeste do Pará – Brasil.(Universidade Federal do Pará, 2009-11-06) PINHEIRO, Ana Valéria dos Reis; GOUVEIA, José Luiz; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626; 9626349043103626Castanhal was chosen for this work for being one of the cities with the most demographic growth and also for having its public water supply taken from the Pirabas aquiferous system, whiose main characteristic as the fact that it is formed by carbonaceous rocks. The hypothesis suggested in this work is that this lithology explains the loss of drilling fluid that occurred during the drilling of the three wells in the Jaderlândia district, what can yield a subsurface collapse. The methodology applied in this work consisted of several techniques remote sensing, geomorphology, neotectonics, hydrogeology, geophysics and environmental analysis. The maps were prepared utilizing a Landasat -5/TM satellite images, SRTM images, aerial photos in 1: 70.000 scale and orthophotos mosaics in 1: 10.000 scale. To enhance the geological data, geophysical methods such as gravimetry, resistivity, and well logging: γ rays, spontaneous potential and resistance were applied. The hydrogeological study of Castanhal city was conducted mainly by using data from wells intended for public water supply and from private wells. Geologically, the northeast region of Pará state, where Castanhal city is located, is composed by Pós-Barreiras sediments and Barreiras Group rocks, that are underlied by Pirabas Formation, of calcareous constitution which is the focus of this work. The drainage system is structurally ordered and is represented by a stockwork pattern striking mainly NE-SW and NW-SE, withstrong asymmetry, which allowed to visualize a tectonic sectioning of the Sheet Castanhal SA.23-V-C-I including the Castanhal city, identifying in this way high and low blocks that where confirmed by lithostratigraphics profiles of the wells and by the geophysical survey. The tectonic structure is congruous with the dextral system transcorrent of Riedel, and still contains relaystructures found in all the Sheet of Castanhal, favoring to the recharge of the water-bearing systems; however, this increases its vulnerability to contamination. The hydraulical load and the underground flow present a zone of recharge in the center of the Castanhal city and another one in the Village of Apeú, and indicate effluent draining. The analysis of the quality of the waters showed high contents of total iron and turbidness in some wells and of calcium carbonate in the wells supplied by the Pirabas aquifer system. The gravity survey showed a positive anomaly inthe center of the city, indicating a less deep basement, what was corroborated by the resistivitysurvey. In Jaderlândia and Bom Jesus quarters in the city of Castanhal negative anomalies lined up, concordant with drainage alignments of NW direction indicating the construction of two4 karstics buildings between 60 m and 100 m of depth and 200 m and 400 m of extension representing a high risk of collapse in these quarters to occur. The interaction of the abovementioned information made possible the elaboration of geological sections, blocks diagrams and thematic maps that gave origin to the map of environmental risk for the city of Castanhal.Item Acesso aberto (Open Access) O valor econômico e estratégico das águas da Amazônia(Universidade Federal do Pará, 2006-03-22) DUARTE, André Augusto Azevedo Montenegro; RIBEIRO, Mário Ramos; http://lattes.cnpq.br/4314158355862373; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Water is, in itself, a natural resource that is indispensable for life, extremely important for metabolism and socioeconomic processes and vital for balancing and maintaining climatic conditions and the environment in general. The asset “water” in its ontological aspect, that is, as a substance in itself, as well as a socioeconomic entity, and the waters of Amazonia in particular, may have their ECONOMIC VALUE measured or calculated, to be expressed in monetary units, guided by the principle that these waters are a STRATEGIC ASSET. This thesis does not restrict the condition of water’s existence only to the physical liquid state of the substance, nor to the principles that the value of this asset originates or is derived from economic/financial costs of obtaining, treating, storing or distributing it, nor yet to that which is obtained under the focus of scarcity. “The Value of Non-Use” or “of the Existence” of the object of this study is the principle focus of this thesis. The Amazon region possesses the largest reserves of freshwater, tropical forest and biodiversity on the planet. The complex system resulting from this interaction, in the dynamic and functional, as well as static (stocks) aspects, is generated and its maintenance will only be possible if there is no significant alteration in the regional hydrological cycle, which is vitally important to the Earth’s climatic equilibrium, through carrying heat and humidity, and, more specifically, when it is expressed as support for productive activities in the Brazilian territory that are of great economic relevance. Thus, it is important that strategies be identified, mechanisms be created and parameters be established for managing this immense natural resource, with compensatory mechanisms and policies being presented, including the transfer of financial resources that can promote socioeconomic development for the region. The research that informed the development of this thesis has a theoretical, conceptual and multidisciplinary character, involving knowledge of geosciences (geology, meteorology, hydrology), economics, engineering, public policies, ecology and sociology, with two principal lines of thinking: hydrological and economic.Item Acesso aberto (Open Access) A viabilidade econômica e técnica da utilização de poços tubulares para o abastecimento de água na região de Belém e Ananindeua(Universidade Federal do Pará, 2006-10-31) KOURY, Felipe de Souza Moitta; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626In the next decades, the economic development and the stability politics of the nations they will be on to the water availability candy in its territories. The water will be a so important product how much the oil or the technology and its scarcity or abundant can will provoke the start of unexpected conflicts in scale. This problem has as initial step for its good solution, the complete knowledge of the hydrologic cycle, that will technical allow to an evaluation correct insurance and of the availability of the hidrics resources of a region. And an important part is to understand what it happens with the ground waters, that are without doubt the part most unknown of the related cycle. E also to know the availability of the water-bearing systems and the quality of its waters is primordial for the establishment of one politics of management of ground water. The full exploitation of the underground hydrics resources depends on hydrogeological comments, analyses and conclusions that more allow the captation of the water in the adjusted places in depth terms, outflow and quality of the water. In such a way, the stages of the developed work had been the following ones: characteristics of the hydroclimatic and meteorological picture, evaluation of the geologic units, register in cadastre of deep tubular wells, chemical analysis of waters of the water-bearing ones of the region, evaluation of the degree of vulnerability of ground waters, calculate of the hydrics reserves and economic comparison enters ground water and superficial water for choice of the source to be caught for the system of public supplying. The population of Belém esteem for the year of 2006 is of 1.444.618 habitants, distributed in an area of 210 km² and for Ananindeua 488.106 habitants, in a 184 area of km². The climate of the region is equatorial humid, of the Af type, and the hydric crocking indicates that in the period of January the September has water excess in the ground, what results in superficial draining and infiltration of this water in the ground, and that in the months of October and November has water deficiency in the ground. The waters of the free aquifer are acids, presenting pH between 3,4 and 5,7, low electric condutivit. Are labeled chloride sodium or bicarbonate sodium. The waters of the Pirabas aquifer are of excellent quality and are classified as bicarbonated calcic, alkaline and present high values of electric condutivit, hardness and alkalinity of bicarbonate. The Pirabas aquifer configures as the best option for ground water exploration, having wells between 250 and 350 meters of depth, they supply the outflows of 250 up to 380 m³/h, being for these characteristics the most indicated for public supplying. The degree of vulnerability of the Pirabas aquifer is considered low to neglecter, due to thickness of the zone not saturated and the lytologics and structural characteristics, being more protected of the infiltration of contaminantes and therefore less vulnerable to the pollution. The region of Belém and Ananindeua has reserve total of ground water of 10,71 billion cubical meters in the year, and a reserve of exploration of 134,7 million cubical meters in the year, represents all regulating reserve more 30% of the permanent reserve in the 50 years. The per capita underground hydric availability is of 190 liters/day. As the addition of the demand until the year of 2025 it is of 57,03 million cubical meters of water in the year, will be necessary to take care of to this addition the construction of 65 deep wells with outflow measured of 250 m³/h, operating in a regimen of bombardment of 16 hours in the day or then 52 wells if the regimen of bombardment will be of 20 hours in the day. Being also that the necessary investment for the construction of these wells will be made title throughout this period of 20 years. Since the price of the cubical meter of groundwater is 33.60% cheaper than the superficial water, then this option if configures as the most indicated to take care of the public supplying. Considering the raised hypotheses, it can be concluded that ground water use proceeding from the Pirabas aquifer is the best option for magnifying of the system of water supply for the region of Belém and Ananindeua. A time that the decision taken for the COSANPA was of magnifying of the system of water supply of Belém and Ananindeua from superficial waters the this option alone will be applicable after 2025, where for the estimates of population growth the system will need magnifying again.
