| Title : | EFFICIENCY OF INTERO MODEL TO PREDICT SOIL EROSION INTENSITY AND SEDIMENT YIELD IN KHAMSAN REPRESENTATIVE WATERSHED (WEST OF IRAN) |
| Abstract : | Application of empirical models is inevitable because of the complexity of process, features, spatial and temporal variation of soil erosion and non-existence or lack of associated data. In the present study, maximum outflow and soil erosion intensity were predicted for Khamsan representative watershed in West of Iran, using IntEro model. The results of production of erosion material in the river basin (W year), coefficient of the deposit retention (Ru) and real soil losses (G year) were then compared with the measured soil erosion, SDR and sediment yield data in Khamsan watershed. The intensity of the erosion process were medium in studied watershed. The predicted data were compared with the measured sediment yield of studied watershed and verified the acceptable results of the IntEro model in Khamsan representative watershed. The results showed that the peak flow is 27.50 m3s-1 for a return period of 100 years. The value of Z coefficient of 0.876 indicates that the river basin belongs to the second destruction category out of five. The calculated net soil loss from the river basin was 12263.44 m3 per year, specific 282.81 m3km-2 per year. The strength of the erosion process is strong, and according to the erosion type, it is surface erosion. |
