SOIL LOSS ESTIMATION OF S7-2 CATCHMENT OF THE SHIRINDAREH WATERSHED, IRAN USING THE RIVER BASIN MODEL

Abstract

This study aims to estimate the soil loss of S7-2 Watershed of Shirindareh River
Basin in Iran, using a simple but comprehensive “River Basin” model for erosion
classification and prediction of erosion potential. Peak discharge from the S7-2
Watershed was calculated on 65 m3s-1 for the incidence of 100 years; the net soil
loss on 4397 m³km-², specific 178 m³ km-² per year. The results of the research and
earlier application of the “River Basin” model in the studied area of the Shirindareh
River Basin in Iran shown that this approach is a good tool for rapid assessment of
erosion risk to support decision-making and policy development.
