Description :
Mediterranean landscapes are characterized by a great diversity of physiography and land use, and as a consequence erosion and deposition patterns are highly variable spatially. To document such spatial variability, a slope transect located in the subhumid Pre-Pyrenean mountains (NE Spain) was selected to use 137Cs and 210Pbex to assess medium- and longer-term soil redistribution rates. The spatial distribution of the radionuclides along the transect reflects the effects of different land use and slope gradient on water erosion. The results obtained confirm the potential for using 137Cs and 210Pbex measurements for assessing soil redistribution on slopes in the Mediterranean environment over different temporal scales.
