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

been employed with the best available data sets on K-, C-, R- and LS-factors. Model results show that soil losses in Hesse vary between 0.5 and 15 tonnes/(ha.year). The mean loss amounts and the sediment delivery ratios for sub-catchments are also
evaluated. Uncertainty analyses reveal an overall error of 34 % of the model results and outline the contribution of each input data set. The findings from this study are used for policy support in the field of soil and water resources management.

uses the runoff coefficient, QR, as an additional independent variable in order to develop an empirical model allowing prediction of storm soil loss values that do not necessarily increase with λ. This model allows Ae predictions that both increase
