Utilização das barragens subterrâneas no estado de Pernambuco.

Abstract

The heterogeneity of agro-climatic, social and economic situation in the Brazilian semi-arid land requires some local adaptations of water resources uses and conservation technologies. For this reason, there are many alternatives for the acquisition of clean water. Among those we can outline the rational exploration of underground alluvial reservoirs, which, in the present situation of water necessity in the region, are as important as any major underground reservoir. In this work, an approach was made about one alternative being the construction of subsurface dams in the Northeast region of Brazil, where the qualitative behavior of the alluvial reservoir and the use was analyzed.
