Compare the MPSIAC and EPM Models for Estimating Erosion and Sediment in poorahmadi catchment. E.E.R.. 2012; 1 (4) :53-67
Abstract:   (16618 Views)

to estimating erosion and sediment in the Poorahmadi watershed basin, MPSIAC and EPM models was used and compared.  Part of Required data about natural characteristics of studing watershed basin provided from comprehensive studies of Watershed Basin and the other part prepared through digital image processing and preparing required maps  using RS and GIS joint capabilities.  With calculating the required factors, amount of erosion calculated in MPSIAC and EPM models. in the MPSIAC model, special erosion and special sediment respectively calculated1903/72 (M³/KM²/y) and 616/03(M³/KM²/y). However, the rate of special erosion and special sediment  in the EPM  model was estimated respectively 1093/5 (M³/KM²/y) and 1015/8 (M³/KM²/y). Results showed that in some sub basins MPSIAC and EPM  models have good coincidence, but in areas with high erosion EPM Model has less certainty than MPSIAC model.
