Avaliação do aporte de água no município de Crateús -CE, em anos sucessivos de seca

Abstract

The study area comprises the hydrographic basin of the outback of Crateús, located in the Northeast semiarid. The study objective was avaliate the water aport in Crateús - CE. Addressing climate dynamics, the water supply maintenance along the years of intense drought, the importance and quality of subterranean water. The used methodology consists of bibliographic analysis, the field work, and collecting subterraneam water for physicochemical analysis. The obtained results show that, in the region, is possible to observe dry and full cycles, that is a own characteristic of semiarid; To keep the hidrical security in the six years of drought were used water pipelines of all fountains of the region, water tank trucks and subterranean water; The region wells contain brackish water, therefore, some wells use desalination, that proved to be an efficient technology in water treatment, although residues are generated in the process. Thus, the verified situations in the basin sectors remit to the need of a planned intervention, that privilegie the appropriate practices for sustainable development and environment education, turned to hidrical shortages.
