Abstract：In order to use experiences and lessons of earlier river management and soil and water conservation in USA for references, 5 large river basins have been selected in this paper to study effects of sediment reduction contributed by soil and water conservation practices. The five river basins include Willos stream of upper Missouri river, Lloyd Shoals Reservoir watershed, Lake Waco watershed, Duck river watershed of Tennessee River basin, upper Colorado River basin. Excluding the factors of rainfall and water conservancy project construction, the analysis results show that the sediment reduction effects of soil and water conservation practices in these basins are very obvious in the contrast analysis between 10 to 32 years, sediment reduction rates of these basins ranges from 38% to 55%.
