Análise estrutural para a compreensão do comportamento hidráulico de água subterrânea na cidade de Parauapebas-Pa

Abstract

Groundwater is a valuable resource that has a restrict use mainly in crystalline terrains, because the exploration it is harder compared to surface water. In cities where there are problems with water supplies such as Parauapebas, groundwater is an excellent alternative to supply this demand, however because this city lies in a crystalline terrain the search for groundwater not always generate good results. Heterogeneous crystalline terrains hydrogeology is, in many ways, different from classical hydrogeology, in porous terrains; in which water accumulates in rock pores. In crystalline terrains, water accumulation relies in spaces created by rock faults and fractures and their interconnection. To understand this relation, in this work were analyzed satellite images e data from wells from all over Parauapebas city, this data have allowed the construction of structural and drainage maps and also a groundwater level three-dimensional model.
