A method has been developed in the present study for the determination of the sediment yield from a catchment using a GIS. The method involves spatial disaggregation of the catchment into cells having uniform soil erosion characteristics. The surface erosion from each of the discretized cells is routed to the catchment outlet using the concept of sediment delivery ratio, which is defined as a f...

The importance of initial sediment conditions on model calibration and validation is analysed. A sediment model was calibrated and validated under three different initial sediment conditions: (0) no sediment availability, (1) calibration of the initial sediment condition and (2) using a warm-up simulation. The model results were assessed in terms of the graphic of fine sediment transport, or se...

Small watershed sediment yield data were evaluated for eight small watersheds ranging from 35.2 to 159.5 ha within the United States Department of Agriculture – Agricultural Research Service Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona, USA. Stock pond sediment accumulation measurements covering time periods from 30 to 47 years were combined with water level records and es...
