Resumen
Computer models that simulate and quantify geomorphologic processes at different spatial and temporal scales had been developed over recent decades. These models provide information that by instrumental manner would be too expensive to obtain. For this study the internationally used model Soil and Water Assessment Tool (SWAT) was selected. The characteristics of the model allow the evaluation of different processes, such as the production and export of sediments in river catchments. The simulated scenarios are constructed through a Geographic Information System (GIS). The model discriminates homogeneous units with unique characteristics of substrate, land cover and slope. From these units the model calculates the sediment mobility. In this study the sediment yield produced by a catchment, composed mainly by Eocene marls located in the Central Spanish Pyrenees, was assessed. Because the erodible nature of the marls the catchment is highly degraded with significant sediment yield and transport to the Barasona reservoir.
