The variation of water levels of this reach and the back silting of watercourse after sand excavation are calculated. The rationality of the results calculated by this model and the measured data are validated and analyzed. The results show that, this model is reasonable and reliable. %K sand excavation %K water-sand mathematic model %K flood control safety %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=759
