Rainfall erosivity in the Upper Llobregat Basin, SE Pyrenees

The aim of this study was to determine the spatial distribution of rainfall erosivity in a 504 km2 river basin in Eastern Pyrenees and assess its uncertainties. The study area is topographically complex and is dominated by Mediterranean climate with intense rains during summer. Available rainfall da...
