Abstract:: The predominate 11.2 km² sedimentation area of the Yellow River lies between Hekou and Longmen, where the river runs through 725.1 km in length, with a drop of 607.3 m and a water surface slope of 0.084%. The Shiwang River is one of the first level tributaries of the Yellow River west to the area from Wubu to Longmen, with a drainage area located at the transition zone of the loess hilly gully region and the plateau gully region. This paper has provided a solid basis for the comprehensive control of the Yellow River through deep analysis and discussion on the variation of the runoff and sediment of Shiwang River Basin. This paper has analyzed the water and sediment sources and their relation with the rainfall based on the data from 1970 to 1989, and compared the changes in the amount of rainfall, runoff and sediment during different periods based on the data from 2006 to 2010. The results from the hydrology method have shown the beneficial results of runoff and sediment reduction from soil and water conservation. The double cumulative curve method has been proved reasonable for the water variation analysis of the Shiwang River Basin, which has indicated the relations among rainfall, runoff and sediment. The ratio of runoff and sediment reduction benefits from soil and water conservation measures to the reduction overall has increased year by year, comparied to the ratio of benefits from the rainfall factor. In the recent 30 years, soil and water conservation has been taken more and more seriously by the government. Conservation works carried out on the Loess Plateau Region have the significant influences on runoff and sediment reduction of this drainage area.
