Abstract

Application of SEDIMENT DELIVERY RATIO in watershed level in order to convert measured or estimated amounts of sediment into soil erosion values is necessary for water and soil conservationists.However, the performance of all available models and relying on their results is questionable because of differences in soil erosion and sediment generation process in the watersheds where those models originally developed. Therefore, the present study attempted to correlate the exact values of SEDIMENT DELIVERY RATIOs obtained through measuring soil erosion and sediment generation amounts to climatic and hydrologic characteristics of 11 storm events in Chehelgazi Watershed of GHESHLAGH DAM. The results obtained from modeling process indicated that the SEDIMENT DELIVERY RATIO could be predicted reliably with respective determination coefficient and relative error of about 98 and 33% using peak discharge, runoff volume and erosivity factor variables. The results of t-test analysis also verified nonsignificant difference between observed and estimated SEDIMENT DELIVERY RATIOn obtained through applying developed model.
