Abstract
Land-use has considerable influences on runoff in the semi-arid basin of the Yellow River. Assessing the impacts of land-use changes on runoff characteristics is a vital role for water resources managers. The goal of this study is to evaluate the land-use change impacts on water resources by using the Soil and Water Assessment Tool (SWAT) model. This assessment is needed for a rational organization of water economy activity in the country. Considerable land-use changes have been noticed in the study area. The conversion of land-use to urban land causes uncertainty of parameters in the SWAT model. The results obtained indicate that the SWAT model can be used successfully to assess the impacts of land-use variability on water resources of the study basin. The findings of this research could provide an important reference for soil and water conservation and eco-hydrology of the river basin.
