Description :
From reservoir sedimentation data of 44 Italian catchments, it appeared that there was a (non-significant) positive relation between catchment area and sediment yield. This is in contrast to what is generally expected from the theory of decreasing sediment delivery rates with increasing catchment area. Furthermore, this positive relation suggests that processes other than upland erosion are responsible for catchment sediment yield. Here, the AA. explore the potential of the Factoring Scoring Model (FSM) and the Pacific Southwest Interagency Committee (PSIAC) model to predict sediment yield and indicate the most important sediment sources.
