Abstract

In this paper a multi-parameter fingerprinting method is used to determine the sediment contribution of gully erosion (Scg) in three catchments in Iran, with different areas and drainage densities. Tracers including carbon, nitrogen, C/N, phosphorus and 137Cs which provide a clear distinction between subsoil and topsoil were used. The mean value of Scg, the efficiency of the composite tracer, the variation of Scg, and finally the accuracy of model calculations for each tracer are discussed. Land managers, who rely on results of erosion models which mainly focus on rill and sheet erosion, should consider these results, which demonstrate the importance of gullies as a major sediment source
