Abstract:   (5615 Views)
The application of various models with different structures and applications for the as-sessment of hydrologic events such as floods and soil erosion is of much interest to both experts and decision-makers owing to a potential saving of time and money. The most re-cent version (1982) of the SEdimentology by DIstributed MOdel Treatment approach (henceforth SEDIMOT II) as a tool for flood and sediment estimation was selected to be evaluated for its applicability to the experimental Amameh watershed in Iran. The main watershed, with an area of 3712 ha, was divided into 12 sub-areas and required inputs were extracted for each of them. Afterwards, 12 storm events with a coincident hyeto-graph, hydrograph and sediment data were selected to run the model. A high degree of agreement of 92% was found between the computed peak discharge and the observed data whereas the applicability of the model in sediment yield estimation was found to be poor.
