Abstract

To day, the progressive of technology and access able various software and also to recognize in significant parameters of soil erosion and sediment yield is provided in possibility of using different mathematical models. The models, demonstrate to create of hydrologicalevents through mathematical relationships between catchment's parameters. Whereas, the results of using some of models has been satisfied for this purpose. Therefore, using of these models is increased in the most watersheds through more than 40 models. Other side, as the mountainous catchments is very complicated, so simulation models are suitable for estimation of erosion and sediment yield. One of the reliable models for above purpose, is known SWAT MODEL. Where is applied in AMAMEH CATCHMENTS. SWAT MODEL has been modified. At present study, the SWAT MODEL has calibrated by monthly and annually observed data, which is recorded in Amameh stations with monthly and daily estimated data, which are obtained by model. In this study catchment's parameters are used as physical parameters for SWAT MODEL. After calibration process, the model has been evaluated by some of sensitivity testing models such as, Nash - Sutcliff model and P-bias model. This process is shown which some of physical parameters are sensitive among the another parameters of the SWAT MODEL such as, K (Soil erodibility parameters) and n (Roughness coefficient parameters). In final, the determine coefficient of observed value and estimated value is obtained, R2=0.74. This result can be obtained for unpaged catchments at same hydrological condition.
