Exploration on Ways of Sediment Treatment of Xiaolangdi Reservoir

According to the practice of high concentration slurry pipe transport of warping projects conducted in the lower Yellow River and the achievements of scientific research,it puts forward to disturb and pump sediment during the two periods of a regulated discharge regime of the river and power generation and water supply within the range of 2-40 km in front of the dam done by submerged suction-type sediment disturbing boats,discharging the fine particle sediment that deposited on the reservoir bottom out of the reservoir in the light of the principle of siphon and reservoir scour.The analysis shows that the plan is economic and workable.It can achieve the objectives of extending the lifetime of the Xiaolangdi Reservoir and transporting sediment into the sea through the coordination and cooperation of reservoir regulation and cleaning.
