| Abstract: | In the last decades the construction of large hydraulic projects on alluvial rivers in China has spurred the development of both physical and one-dimensional mathematical modeling to the point that deposition and erosion predicted by modeling in either way conform to prototype observations over periods of 3 to 19 years. The prototype data are those of Gezhouba on the Yangtze River and Danjiangkou on the Han River. The accuracy attained is in the neighborhood of 20% which is considered good enough in sedimentation engineering. Thus these techniques of modeling may be applied to forecast the impacts of hydraulic structures on an alluvial river. Mathematical modeling in 2 space variables has also been developed, but still awaits further verification. |
