The analyses of the results showed that the basin presents risks geoambientais and that the tendency of occupation of the soil and the demographic growth, they generated areas potentially problems once the disordered occupation of the physical middle caused the degradation of the natural resources of the soil, of the vegetation and they contributed considerably for to deterioration of the resources hidrics.
