Abstract

The study focuses on 2 small basins (W2 and W3) located near Crotone, in Calabria, for which measurements of suspended sediment yield are available. Both the catchments originally supported a rangeland vegetation cover and they were planted with eucalyptus trees in 1968. Attention focused on combining information on sediment yield from the 2 catchments obtained using traditional monitoring, with measurements of the fallout radionuclides caesium-137 and excess lead-210 undertaken on sediment samples from the study catchments. The results demonstrate that the areas of greatest soil loss are associated with the slopes where the tree cover is discontinuous, and that forest harvesting by clearcutting causes significant short-term increases in sediment mobilisation and sediment yield
