This study investigates area-specific Sediment Yield (SY) in Mediterranean badland areas at different spatial scales
using a SY-database compiled from scientific literature. Relationships between the plot and catchment characteristics and the corresponding SY-data are analyzed. Results indicate that in Mediterranean environments SY is larger than in other environments, especially in badlands where a high variability of SY is observed depending on the spatial scale. In intensively gullied badlands,a complex plot or drainage area (A) – SY relationship is observed: for A ranging between 10–5 and 10 ha,SY is very high (mean SY equals 475 t ha–1 yr–1),whereas for A > 10 ha,SY decreases with increasing A (mean SY < 100 t ha–1 yr–1).
