It searched analyze the naturals and the occupation of area characters through survey of fact, search of bibliography, Fieldwork, mapping of morphologic and morphometric characters in this basin, mapping land use, interviews with residents, separation of inundations area / accident and elaboration of susceptibility map. For the mapping we adopted the scale 1/20.000. The results took a conclusion that the inundations happen because the condition of physical process that was intensify for basin occupation. The naturals conditions, related of physical process, include the regime of rain of the region, the high slope in the portion more higher of the basin, like relief rugosity, the variation hypsometric, tendency to the concentration of the flow in some concave segments, the form the hydrographic basin and the existence of inundation plain in half basin, the siltation and strangle of the drainage.
