Abstract

This study used the MPSIAC and EPM MODELs as a comparison to estimate erosion and sediment in the Poorahmadi Watershed Basin. Required data regarding the natural characteristics of studying the watershed basin was provided from comprehensive studies of this in addition to digital image processing and preparation of the required maps using the joint capabilities of RS and GIS. By using the required factors, the amount of erosion was calculated in both the MPSIAC and EPM MODELs. In the MPSIAC MODEL, erosion was calculated to be 1903.72 m3/km2/y, whereas sediment was calculated as 616.03 m3/km2/y. However, the rate of erosion in the EPM MODEL was estimated to be 1093.5 m3/km2/y and for sediment, it was 1015.8 m3/km2/y. The results showed that in some subbasins there was good correlation between the MPSIAC and EPM MODELs, however in areas with high erosion the EPM MODEL has less certainty than the MPSIAC MODEL.
