Estudo hidrológico e das precipitações na bacia hidrográfica do Reservatório Acarape do meio

Abstract

One of the great challenges of environmental management is to reconcile preservation with multiple uses, being fundamental knowledge of the factors conditioning the changes in the natural conditions of the reservoirs and the respective watershed. The study of hydrological conditions of reservoirs provides the best management of water resources, especially in the Northeast region, where long periods of drought occur. The objective of this work was to evaluate the morphometric and morphological characteristics of the hydrographic basin of the Acarape do Meio reservoir, located in the municipality of Redenção, Ceará. To perform the physiographic characterization of the river basin, the software AutoCAD was used, in which the delimitations of the areas, the perimeters and the axial lengths of the basin were obtained. The precipitation data, corresponding to the historical series were obtained from the National Water Agency (ANA) website. For the characterization of the dimension-area-volume parameter in this work, the technical data of the dam selected in the Electronic Atlas was used. For the study of the historical rainfall series, the Excel software for Precipitation was used for the return period of 1,000 and 10,000 years. From the result of form factor and compactness coefficient it was identified that the hydrographic basin is more elongated and with average propensity to flood.
