中文摘要:

利用非恒定水动力学水流泥沙方程,建立了黄河下河沿～头道拐河段一维水沙输移数学模型,分别采用1997-2002年和2003-2006年的黄河水文、泥沙等资料对模型进行了率定和验证；运用该模型模拟计算了1997-2006年宁蒙灌区引水对河道水沙变化的影响,分析认为:宁蒙灌区每引水1亿m3,头道拐断面相应径流减少量0.69亿m3,每净引水1亿m3头道拐断面径流则减少1.02亿m3；相应输沙减少量分别为40.9万t和60.7万t；河道淤积变化量1432万t.汛期引水对河道输沙变化的影响大于对径流变化的影响,汛期引水引起的头道拐断面径流减少量占引水期径流减少总量的50％,而相应的输沙减少量则占输沙减少总量的73％.

英文摘要:

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...
