Groundwater and Watershed Analysis

The aim of this paper is to develop a method to the integration of physical environmental data and earth occupation and vegetation coverage maps appropriately to the management processes of groundwater and the proposition of water users rights in the Federal District, Brazil. By the integration of the digital thematic maps it was possible to obtain the infiltration and recharge conditions, the maximum capacity of water retention in the soils, the index of water exploitability and the groundwater exploitation favorability conditions. Based on the results and in field observations, there were proposed criteria to the management of groundwater resources of the Federal District.
