Abstract

The AA. study the impacts of climate change on runoff and soil erosion in 2 Mediterranean watersheds, located in central and southern Portugal, by coupling a seasonal-scale with an event-scale model. PROMES results were used to estimate changes to storm rainfall intensity, while SWAT was applied with the PROMES results to estimate changes to soil moisture and saturation deficit, as well as vegetation cover. The results from both models were used to generate scenarios of changes to storm intensity (increasing), saturation deficit (increasing) and vegetation cover (increasing according to vegetation type). These scenarios were used as input for the MEFIDIS model to study the impacts of these changes on runoff and soil erosion across spatial scales for a set of storms. The results were evaluated at 2 spatial scales, that of fields (considering both (inter-) rill and gully erosion) and that of the entire catchment; and analyzed according to the dominant land-cover types in the catchments
