Numerical simulation of water and sediment change in Ningxia-Inner Mongolia reach and the impact of water diversion on water and sediment change in river course
Using current and sediment equation in the non-constant hydrodynamics,the paper set up a one-dimensional mathematical transport model of water and sediment in the Xia Heyan to Tou Daoguai reach.Using the hydrologic and sediment data of the Yellow River 1997 to 2000 and 2003 to 2006,it calibrated and verified the model.The use of this model simulated and calculated the impact of the irrigation area diversion to the sediment changes in riverway of the Ningxia-Inner Mongolia from 1997 to 2006.The analysis reco...
