中文摘要	基于1997~2011年黄河尾闾河道及河口实测水深、距离、径流量及泥沙量等数据,分析了调水调沙工程实施10年来对尾闾河道及近岸水下岸坡冲淤变化的影响。研究表明,调水调沙工程的长期实施改善了黄河尾闾河道的水沙搭配状况,形成了有利于河道冲刷的水沙条件,使尾闾河道整体处于冲刷状态。水下岸坡的冲淤状况也受到明显影响:在距入海口较近处,泥沙来源丰富,并在25~35km内不断淤积,淤积速率在10年间介于0.18~0.63m/a;在距入海口较远处,泥沙补给较少致使水下岸坡在35km内受到冲刷,冲刷速率在10年间介于0.045~0.18m/a。研究发现,调水调沙工程的长期实施,不但有利于延长黄河现行入海流路的...
英文摘要	Based on the measured water depths,distances,runoff and sediment loads data of the trail channel of the Yellow River and estuary from 1997 to 2011,the impacts of carrying out of the‘Water and Sediment Regulation’in 10 years on the trail channel and near- shore of erosion and deposition variation of the underwater bank slope were analyzed. The researches indicated that the long term implementation of the water and sediment regulation engineering had improved the relationship of water and sediment in the trail of the Yellow River,formed a favorable water and sediment conditions,thus made the trail channel in the washed state as a whole. There was obvious influence on the erosion and deposition of the underwater bank slope: from the nearby of the estuary,sediment source was rich,deposited within 25 ~ 35 km,and the deposition rate was between 0. 18 ~ 0. 63 m / a in10 years; with less supply sediment in the far away from the estuary,the underwater slope had been erosion within 35 km,and the erosion rate was between 0. 045 ~ 0. 18 m / a in 10 years. The study found that the long term water and sediment regulation engineering implementation was not only benefit to prolong the current flow of the Yellow River into the sea,but also changed the state of erosion and deposition of the underwater bank slope,while promoted it towards new balance.
