Abstract

The objective of this research is to analyze, in plan of evolution, the environmental Geomorphology of the forms that, as dynamic object, reflects inductive environment to the occurrence of landslides, evaluating the factors directly and indirectly responsible for the soil resistance to erosion. This is a proposal of integrated action that offers opportunities to the environmental Geomorphologic characterization of the mass movement system in the hill areas of accumulation Glacis in Tabatinga neighborhood, in the municipality of Camaragibe, inserted in the Barreiras Group. The methodology was comprised of mineralogical analyses, bimonthly monitoring of hills and the materializing erosion of its edges. Identification and evaluation of the impacts were based on LEOPOLD (1994) and GOMEZ (1994), adapted by OLIVEIRA (1998). As a result of the  mineralogical analysis, clay predominance was diagnosed (56.8%). The sources suffer significant loss according to the monitored areas. As for the impact evaluation, 27 were identified. From the total, only 4 were positives.
