Experimental Study on Application of Combined Technology of Diversion Dike and Sediment Desilting Channel in Reservoir's Sediment Desilting

In view of the sediment deposition problem in Kezier Reservoir,the application of the combined technology of diversion dike and sediment desilting channel in the sediment desilting of the reservoir is studied here through physical model tests.Under general flow,by using the combined technology,the main sediment scouring channel could be faster formed,through which the upstream sediment could be desilted effectively.So this combined technology is feasible in the sediment desilting of reservoir,at the same time,it could be used with other sediment desilting measures to recover reservoir storage faster.This combined technology could also provide another new idea for the sediment desilting of the reservoir in water and economy restriction.
