Abstract: Water and sediment regulation is a symbol project which the Yellow River Administration carries out the transition for method of harnessing the Yellow River. The purpose is to form rational water and sand process during the real-time dispatching of the reservoir. It benefits to control the sediment in the lower reach of the Yellow River, even to scour alongside the whole river, and achieve the purpose that the river bed can¡¯t be raised. In short, utilize Xiaolangdi Reservoir to store water, discharge with high flow, artificially make flood peak, scour the river in the lower reach, and increase the safety of flood prevention and control. Since 2002, Yellow River Administration has made water and sediment regulation in successive years, trial has been changed into running. The water and sediment regulation will make the river deep by scouring. The water lever of the Yellow River will decrease under the situation of same flow. The water diversion capacity of the irrigating district will also decrease. In additional, being influenced by the limit of water from the upper reach as well as the existing problems of headwork of the Yellow River diversion and Yellow River diversion irrigation district, the problems of demand and supply for Yellow River diversion irrigation district will continuously increase. Based on the conditions of water and sediment regulation of the Yellow River, incorporated with the actual situation of Xiaokaihe irrigation district, we have preliminarily investigated and analyzed the existing problems for irrigation of the Yellow River diversion and also provided related countermeasures and suggestions in this text.

Key words: Water and sediment regulation, Irrigation of the Yellow River diversion; Existing problems; Discussion
