Simulação numérica de fluxo de águas subterrâneas no bloco S11D e relação entre o fluxo subterrâneo com o desenvolvimento das cavidades naturais da Serra Sul, província mineral de Carajás - PÁ

Abstract

The work it is the local hydrodynamic study through the hydrogeological modeling of the Carajás basin, the area of influence of the body S11 Block D, the Canaanite city of Carajas, northern Brazil. Extracted hydrogeological information of the Sierra South, in Carajas, gave focus to the knowledge of the evolutionary history of cavities contained in the region. With the aim of constructing a numerical flow model and a relationship with the natural development of cavities. Using the structural model of Riedel important boundary conditions and hydrodynamic elements. In addition to a characterization of the units and systems aquifers in the region. From the results obtained, to regions of dento area towards the east, the model proved to be very favorable in relation to the behavior of water in the subsurface and the direction of development of cavities. The relationship between the cavities within the context of the region shown very favorable when associated with the first two hydrogeological units, which are enclosed most of the cavities. Our data modeling, contributed to clarifying the hydrogeological behavior narrowly to Block D.
