Quantifying erosion using 137Cs and 210Pb in cultivated soils in three Mediterranean watershed: Synthesis study from El Hachef, Raouz and Nakhla (North West Morocco)

► We present results on soil erosion quantification using 137Cs and 210Pb. ► In each area inventories of 137Cs and 210Pbex were measured in cultivated soils. ► The mean erosion rates varied from 16 to 41 t.ha−1.yr−1. ► These results show the severity of erosion in North West Morocco.
