Comparison of methods for evaluation of erosion deposition processes on cultivated soils

摘要

The potentials of different methods for evaluating the erosion of soils and accumulation of sediments were compared in a detailed study of a small catchment. Morphological, isotopic, and sediment correlation methods were used, as well as the calculation using the modified USLE and the SHI (State Hydrological Institute) procedures. It was shown that each of these techniques can be used for evaluating the mean annual erosion rate from cultivated soils, but only the morphological and radioisotopic methods permit the evaluation of spatial distribution of the zones of erosion and deposition of sediments within the catchment.
