变化环境下七里山水域高洪水位研究
Study on high flood level of Qilishan Waters in changing environment
摘要
Abstract
Qilishan Waters is the confluence of the Dongting Lake into the Yangtze River.Affected by clean water discharging from the Three Gorges Project and upstream Xiluodu Reservoir and Xiangjiaba Reservoir,there are many new changes occurred in this area,such as water flow and sediment transport,river sedimentation and variation of river regime,river flood storage-discharge relationship,flood level and discharge capacity and so on,which have an effect on the flood control and storage pattern in the middle reaches of the Yangtze River,especially in the Dongting Lake.Based on the water-sediment integrate macro mathematical model of the Yangtze River,a locally refined 2D flow-sediment numerical simulation model of Qilishan waters was developed,researching the flood control and storage problems for various typical floods after reservoir group operation under different control levels and different enabled flood detentions.For the type of 1998 flood,through the regulation of Three Gorges dam and raising up 0.5m of the Qilishan control water level,there may be no need to utilize the flood storage areas;however,for the type of 1954 flood,flood storage areas of Dongting Lake and Honghu Lake are still required to be used.关键词
