RESUMO

The completion, implementation or realization of researches aimed to the qualitative and quantitative data of the weathering mantle of slopes of humid tropical environments is extremely scarce. Knowledge of thickness and volume data of the weathering mantle, mainly in the landslides risk areas, may be very useful for the establishment of preventive measures and monitoring of structural character. This research aimed to perform the calculation of the weathering mantle volume of the slopes of Tavares river basin, in Ubatuba - SP. For this, were used such field procedures and geostatistical analyses of a Geographic Information System in order to obtain as a result a Digital Elevation Model that represents the thickness of the weathering mantle of the study area and thus reveal the volume of material between the surface of soil and the mantle/rock contact. After of the completion of all this steps, were compiled some hypotheses that attempt to explain why, after the validation, the model was considered impracticable to apply
