流域洪水资源利用的理论框架探讨Ⅱ:应用实例
Theoretical framework of floodwater resources utilization in a basin Ⅱ : cases study
摘要
Abstract
To verify the rationality and universality of floodwater resources utilization pattern built in the part Ⅰ of this paper,an application case is carried out in the Nansi Lake basin.First of all,the present situation and development potential of flood resources utilization is evaluated,according to hydrologic data during 1974-2008 years,annual average actual availability is 1.467 billion cubic meters,the present potential and the theoretical potential are 288 million cubic meters and 733 million cubic meters,with the present utilization rate of 64.9 ％.Secondly,based on the elements of the flood control system,the choosing process for the floodwater resources utilization patterns is discussed,and then two potential development patterns,multiple duration flood limited water levels of the Erjiba Dam and floodwater distribution among rivers by sluice gates in the west region of the Nansi Lake,are taken as reasonable.The flood limited water level during the later flood season (from August 21 to September 30) can increase from 34.20 m to 34.35m,which the utilizable capacity of the Nansi Lake increases by 89.4 million cubic meters,and the peak level of the Nansi Lake increases gently by 0.02-0.026 m.The optimized scheme for floodwater distribution among rivers in the west region of the Nansi Lake is put forward,which can increase water storage 135.8 million cubic meters on the premise of without increasing the risk of flood control dramatically.The results above show the development pattern of flood water resources utilization in a basin scale is reasonable and feasible which include potential evaluation,development patterns choose and decision making by balancing the risks and benefits.关键词
