SEDIMENTATION OF SANZUODIAN RESERVOIR

摘要

Being located in the Yinhe River, Sanzuodian Reservoir is faced with serious sedimentation. There exits a sharp contradiction between water supply and reservoir deposition. A mathematical model is developed to forecast the state of reservoir sedimentation. Major factors concerning the reservoir design, such as reservoir operation manner, dam scope, dam site as well as discharge facility, are studied. Also ways to reduce sedimentation such as lowering the pool level during floods, using density flow, etc. are discussed.
