The geological processes of surface dynamics have caused many social, economical and environmental problems in the last years in Brazil, generated by a catastrophic sequence of events associated with torrential rains, that has affected urban areas and enterprises in general such as dams, for example. This project has the objetive of evaluating physiographic parameters and land use and occupation associated with the occurrence of landslides on slopes surrounding of earth dams in the basin of Ribeirão Roque, establishing the vulnerability of buses to these processes. It is noteworthy that the basin of Ribeirão Roque, has 95 earth dams of small and medium size, and 78.95% do not have granted the Department of Water and Electrical Energy of the State of São Paulo (DAEE), and other buildings along the basin, also highlights is that this basin has suffered the rupture of dams, causing damage to farms and building sites. The following steps were performed in the research: literature; database organization; definition of susceptibility to landslides; survey of dams in the basin; drafting Charter Preliminary Susceptibility to Landslides; field survey and drafting of the Charter Final Landslide Susceptibility; and setting criteria for definition of the Dams Vulnerability. As a final product of the project were prepared Susceptibility Letters to Landslides and Letter of Dams vulnerability, which can analyze regions according to their greater susceptibility to landslide processes and the vulnerability of each dam, respectively. They can be used as support in dam management. As most dams are from medium to high susceptibility, since the land contributes to landslides processes, it is necessary to make the realization of a more rigorous survey on the situation of each dam. These products become indispensable tools in the... (Complete abstract electronic acess below)
