| Popis: | The strands are configured as one of the main elements of the landscape, when viewed in a short time, show up with static appearance, however they are continually being worked by erosive or depositional processes. The main objective is to contribute to the understanding of the profile conformation and shape of the slopes up the water-physical parameters of soil cover on slopes situated on lithologies of Santa Maria Formation, in Santa Maria, RS. According to the objectives of the work, it was used as a theoretical and methodological basis the proposal structural analysis of soil cover, which allowed the understanding of the dynamics of soil cover and the relationship with other landscape elements. After analysis of the results, there was obtained the following physical-hydric behavior of horizons diagnoses of the soil profile, where it was identified the process of translocation of clay from superficial diagnostic horizons A, AE, E and EB for subsurface BE and B, these being more durable, impermeable horizons, contributing to turn convex the top of the slope. Already at the slope base, the concave shape is due to regressive erosion of less resistant horizons and the organization thereof, commanded by surface and subsurface water circulation. |
