Description :
Ephemeral gullying is an important erosion process in Mediterranean areas. The objective of this study was to investigate to what extent one could use field measurements of S (local slope) and A (drainage-basin area) to predict the location of ephemeral gully initiation in intensively cultivated Mediterranean environments. Two relatively homogeneous study areas in Southeast Spain and Northeast Portugal with widespread ephemeral gullying were selected.
