Análise descritiva da hidrogeografia do alto da bacia do Paraim - PI

Abstract

The sweet waters are the most used by man, due to the types of use and easy access. This can lead to a serious process of degradation of water resources. It is important to monitor actions and activities developed in the area of a river basin, as it will help define strategies for use, management, control and conservation. Therefore the present work aims to characterize the hydrogeography of the upper Paraim River basin, in the municipality of Corrente, Piauí. The Paraim River basin is one of the most important in the state of Piauí. The study was carried out in the Paraim river basin, in the municipality of Corrente located in Piauí, in a stretch between the source and Barra do Rio, municipality of Sebastião Barros, where it meets the Rio Current. The study had as methodology, bibliographical survey, primary data collection through field visits for field diagnosis and survey of the resident community in the territory, with photographic survey, in addition to cross-referencing information for environmental characterization of the basin under hydrographic aspect Of the area, seeking to raise the composition of the main river, tributaries, estuary and spring. It was verified through this study that the watershed of the Paraim River has in its area of coverage four springs, responsible for the perennial maintenance of its watercourse, located in the surroundings of Chapada das Mangabeiras, in the locality of the Tatu (Garganta da Gia ). The Paraim River has several tributaries among them are rivers, swamps, lakes, ponds streams. Due to the population increase in many places the vegetation is quite devastated due to the felling of houses and for grazing animals. In some points the river banks there is almost no tree due to anthropic action. It has as main affluent the River Silver that makes its perennial maintenance.
