万安枢纽运行对库区河床淤积及防洪、通航影响研究

Influence of reservoir operation on deposition in Wanan Hydro project

本文建立了万安库区一维泥沙数学模型 ,该模型采用的悬沙输移模式能较好的体现悬沙和床沙的交换机理 ,利用该模型对万安水利枢纽运用引起的库区泥沙淤泥、洪水期水位变化、柘水期水深变化等问题进行了分析研究 .

A 1 D sediment mathematical model for reservoir of Wanan Project is established. In the model a new mode of suspended transport of sedimentation for better describing the exchange mechanism between suspended load and bed material is proposed. The model is applied to study the influence of reservoir operation on deposition, water level variation during flood season as well as the changes of water depth for transport in dry season.
