黄河调水调沙的目的是在水库实时调度过程中形成合理的调水调沙过程，有利于下游河道减沙乃至全线冲刷，在原型观测分析的基础上，验证调水调沙和调空调沙指标的合理性，并从调水调沙条件、调水调沙过程中水位流量关系、同流量水位变化、河道冲淤变化等方面分析调水调沙对花园口水文站试验河段的影响。
The purpose of water and sediment regulation in Yellow River is to form the rational flow and sediment process during the reservoir real-time scheduling,which is beneficial to sedimentation reduction,even whole line erosion for the downstream river.Based on the prototype observation and analysis,the paper verifies the index rationality of water and sediment regulation and empty regulation and analyzes the influence of water and sediment regulation to testing river reach of Huayuankou hydrologic station from the following aspects,the condition of upland runoff and sediment,the relation of water level and flow during the water and sediment regulation,water level change with same flow grade,river erosion and deposition change,and so on.
