(Universidade Federal do Pará, 2015-03-23) MARTINS, Vânia Carla Dias; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
This study aimed to assess the risk of flooding and propose alternatives for prevention and containment of flood for the river basin Tucunduba Oxbow River, located in Belem, from the development of methodology for hydrological and hydraulic simulation, aiming the sustainability of macro drainage system, and analyze the physical variables of the basin to be used as input data for the mathematical models, will also be presented in full simulation methodologies. The results show the application of the models mentioned, as essential tools for the prevention and containment of floods on urban drainage basins, which suffer direct influence of the tidal regime. Since the prevention and containment of extreme events such as floods, is an essential tool for urban areas subject to climatic accidents due to the amount of lives involved in the process, disease by the collapse of the sanitation system and impairments on buildings , materials and infrastructure assets.

Estudo da conceituação e implementação de vias sanitárias em Belém: o caso da bacia de drenagem Estrada Nova
(Universidade Federal do Pará, 2004-09-20) LIMA, Henrique Nazareno Santos; LIMA, José Júlio Ferreira; http://lattes.cnpq.br/5176390429456548
This dissertation aims at giving a more specific account of the term sanitary road utilised in sanitary enginnering. It applies principles used in the projects of canal marginal roads, narrow short streets and trunk roads. The study is based on the case of Estrada Nova basin located in the city of Belem. After a characterisation of its fuctioning, its relationships with the urbanistc control is explored in order to be more compatible with land use control. The result of the study presents elements for the a reconsideration fo the definition wihch incorporates the urbanistic situation and needs for drainage projects to be more integrated with the urbanistic functioning of the city.

(Universidade Federal do Pará, 2006) VALE, Elivam Rodrigues; VIEIRA, José Luiz Fernandes; http://lattes.cnpq.br/2739079559531098
The ambient sanitation is one of the most important ways of prevention of illnesses, but unhappyly it is not a reality in all the sectors of the population, generating a preoccupying situation for the professionals of Public Health. Problematic relative to the health and the environment reveals particularly important for the brazilian north region, where people inhabit the edges of rivers and igarapés with lack or even though, infrastructure of sanitation absence, being displayed to possible risks of contamination. In this study, of expedition descriptive character, were used quali-quantitative methods, aiming at bacteriological diagnostics of the water consumed for the marginal inhabitants of the region of the islands, more specifically in the islands of Paulo da Cunha (Grande island) and Murutucu in the agricultural zone of the city of Belém-Pará. 96 water samples stored in the residences and 80 superficial water samples had been collected in ten points located surrounding area of the islands. It was evaluated the number of Termotolerants Coliforms and Standard Counting of Heterotrofics Bacteria in the water stored for consumption, as well as Termotolerants coliforms, fecals Estreptococos/Enterococos and bacterial enteropathogens in the superficial water. In the Grande island the results disclose concentrations that had varied of 25 to 3600, 15 to 420 and 15 to 420, for termotolerants Coliforms, fecals Estreptococos and Enterococos, respectively, in relation to the Murutucu island these values had varied of 540 to 2600, 44 to 680 and 44 to 448, respectively for the same pointers. The presence of Salmonella spp was observed in 27,5% in Grande island and 12.5% in the Murutucu island. It was verified that 58.7% and 66%, of the water samples of consumption in the islands Grande and Murutucu, had been respectively considered improper for consumption, with presence of termotolerants coliforms. In relation to heterotrofics bacteria, 41.3% in Grande island e 15% in the Murutucu island had 500 more than UFC/mL. Considering itself the results gotten in the present work verify that the water used in the agricultural zones can function as a factor of risk to the human health that use it.

Reciclagem como alternativa para a eficiência e sustentabilidade econômica do setor de resíduos sólidos urbanos no município de Belém-PA
(Universidade Federal do Pará, 2018-05-28) SANJAD, Heitor Capela; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
In the research, classified as descriptive and exploratory, the technical efficiency and economic sustainability of the solid urban waste (SUW) sector of the city of Belém - PA was evaluated. The research divided into three stages had in its first phase the execution of the legal, operational and financial diagnosis of the municipality. Then, in the second stage, scenarios were established to recycle 10%, 25% and 50% of MSW generated in the municipality in the year 2017. In the last stage, the sales prices of recyclables were determined and the economic prospects were estimated in the proposed scenarios, besides the evaluation of the financial benefit that the selective collection can bring the public finances. The generation of 340,405.39 tons SUW was verified in the city of Belém, as well as the existing need to update the laws, elaboration of the planning tools and reformulation of the forms of collection of the services provided in the sector. It was also observed that the implementation of recycling of 10%, 25% and 50% of the total RSU mass generated in 2017 would reduce operating expenses by R $ 11,302,703.66, R $ 8,256,759.16 and R $ 56,513,518.32, respectively, in the proposed scenarios. With the work it was possible to conclude that recycling is an excellent alternative to improve infrastructure and reduce expenses in the SUW sector of the municipality of Belém.

SIG aplicado na pré-seleção de áreas para a implantação de aterro sanitário no município de Breves (PA)
(Universidade Federal do Pará, 2016-03-23) ACIOLY, Andreza Vieira; ALVES, Rui Guilherme Cavaleiro de Macedo; http://lattes.cnpq.br/1902384822911246
The inadequate location of the final solid residual disposal is a big problem that can compromise the environmental resources. In Breves city (PA) was developed and applied an area location methodology to implementation de sanitary landfill, using geoprocessing techniques, through Geographic Information System - GIS.In the maps confection were used data shapes from IBGE (2010) in the basic scale 1: 250.000 together with images from do Google Earth and processed using the software Arcgis 10.1. Two buffers delimited respectively from the municipal headquarters from na are of 20 km ray and inside this limite by conditioning environmental questions and flight security, in a 13 km ray to the airport. With the overlap of these upcoming community areas were excluded (500 m) and surface water bodies (200m); and prioritized anthropized and access roads already in place. Three areas were pre-selected. In a second phase these pre-selected areas received grades in own criteria: (a) the proximity of the housing communities; (b) the distance from the surface water sources; (c) the soil characteristics of the land available; and (d) the size of pre-selected areas. The area with the largest amount of notes was chosen as the best among the pre-selected ones. Concluding, it is recommended the methodology applied, for convenience and economy, seen the necessity of dislocation of the teams to the selected place only to prove the facts.
