Abstract
Abstract Geotechnical maps of suitability for urbanization can provide directives for land use in terms of susceptibility to disasters. This paper presents methodological innovations for the development of these maps by incorporating hydrographic basin analysis in a case study conducted in the municipality of Itapevi. The Shalstab (Shallow Slope Stability) model evaluated the susceptibility of an area to landslides and correlated events. Wet zones were mapped by combining the Hand (Height to the Nearest Drainage) model with floodplain mapping and proximity to concave slopes. Participatory mapping delineated critical flood areas and possible impacts of land use on sub-basins. Urbanization trends were modeled using multivariate kernel analysis. This study presents perspectives on disaster risk management integrated with those of basin management.
