Dimensionamento de barragem de acumulação de água para sistema de irrigação de plantio de cacau no sudeste do estado do Pará

Abstract

The Amazon region has high water potential and large natural reservoirs of water existing in the most diverse forms (springs, aquifers, lakes, etc.), however the distribution and access to the resource by the population are unequal, making the demand for water much greater than its availability in certain regions, which leads to water stress. In the Amazon, family farming is a relevant activity in regional sustainable development, and demands part of this resource, which is a limiting factor for regional development. Faced with this reality, water capture, storage and conservation technologies are used, with dams being one of the available technologies that play an important role in the democratization of water use. Therefore, through this research, we seek to design a dam that will serve as an artificial reservoir for water storage, intended for agricultural consumption of cocoa plantation on an agro-family scale on a farm located in the municipality of Novo Repartimento, to optimize its cultivation cycles, combined with the use of new technologies that use local resources and renewable energy sources available in the Amazon. For this, the water demand necessary for the agricultural activity of the enterprise was evaluated, comprising the Water Balance of the location, as well as delimiting the watershed of direct contribution of the dam, allowing the dimensioning of the artificial reservoir to meet the volume of water needed in the activity.
