Abstract

Sediment yield is the most important environmental issues in watershed basins which greatly affects human and animal life. Therefore, soil conservation and sediment control is one of the most important measures that should be paid attention. As various factors such as land use change can affect sediment yield,  this study was performed to investigate the effect of land use change on sediment yield of Kouhdasht basin, located in the west of Lorestan province. For this purpose firstly, land use changes were investigated using satellite imagery and then sediment discharge was estimated using discharge and sediment concentration data of Kashkan Afrine station located at the basin outlet. Finally, the contribution of land use in sediment yield was estimated using the fingerprinting technique based on the Bayesian uncertainty model. The results showed that the change in land use from grazing land and forest to agriculture was significant. So that during 1361-1395, 49 and 24.8% of the grazing and forest lands were reduced, respectively and agricultural lands increased by 47.5%. Also the results obtained from Kashkan Afrine station data showed that the average sediment discharge increased from 5.954 ton/day in 1361 to 7.079 ton/day in 1395. The results of fingerprinting sediment model indicated that the agricultural lands have the most contribution in sediment yield. The contribution (uncertainty of 5 to 95%) of agriculture, grazing land and forest in sediment yield were calculated to be 95 (86-99), 3.1 (0-12) and 0.9 (0-3) percent, respectively and the relative importance of each resources was calculated to be 1.5, 0.28 and 0.03, respectively. These results indicated that the most important factor increasing sediment discharge is the land use change from forest and rangeland to agriculture.
