Abstract

In this research, PSIAC, MPSIAC, EPM, Fournier, Douglas, Musgrave, Stehlik, Kirkby, Geomorphology and Hydrophysical models in BABOLROUD WATERSHED were investigated to determine appropriate model to erosion and sediment estimation. Sediment OBSERVATION DATA (43 years data of Ghoran talar station) was utilized, to evaluation of used models and determine of appropriate model. In order to evaluation of results, STATISTICAL METHODS such as paired t-test, correlation coefficient, relative difference, BIAS, RE, RMSE were used. Results showed that in 95% confidence level, haven’t significant difference between OBSERVATION DATA and results of MPSIAC model and also mentioned model with values of relative difference, BIAS, RE and RMSE 7.93, 0.013, 7.35 and 8.63 relatively, and by correlation coefficient equal 0.86 was the best model identified for estimation of SEDIMENT YIELD in BABOLROUD WATERSHED. Afterward MPSIAC model, Geomorphology model with values of relative difference, correlation coefficient, BIAS, RE and RMSE equal 10.98, 0.78, 0.02, 12.34 and 11.95 relatively and haven’t significant difference in 95% confidence level was the second appropriate model to SEDIMENT YIELD estimation.
