Study of soil-water retention curves on a hillside from the Serra do Mar susceptible to landslides

Resumo

Gravitational mass movements are processes of solid matter transport and exogenous modelling of the relief. In Brazil, the landslides are the most common type, for its climatic and geological dynamics, triggered mainly by rainfall. Particularly, Serra do Mar has become a scene of great incidence these events, due to its climatic, geological and geomorphological characteristics. This research has the objective to develop the modelling of soil-water retention curves of the soil samples collected from B e and C-horizons of four open trenches in a hillside from the Serra do Mar. The soil-water retention curves were studied with drying and wetting pathways. It is aimed to understand of the water flow and possible destabilization processes in the hillside.
