Abstract

This study was conducted to evaluate the role of effective parameters of MPSIAC and EPM models in SEDIMENT yield estimation in TALEGHAN watershed. Different parameters of models and watershed charactristics were extracted through 400 random points via GIS. Statistical analyses were done using stochastic softwares to achieve correlation and stepwise regression. The results showed that annual temprature has a negative significant relation with MPSIAC SEDIMENT yield but, not with EPM. Rain and also slope are important factors which had positive significant relation with SEDIMENT yield of both models. MPSIAC SEDIMENT yield was increased in higher elevations because of their higher slopes while this was negliable in EPM model. As runoff and pick discharge were increased, SEDIMENT yield was increased. Considering GEOLOGY rating, EPM had significat relation with both model ranking methods. The results of multiple regression indicated that canopy and GEOLOGY rating have the most important role in MPSIAC and EPM models, respectively. Slope and runoff also were important agents in both models.
