Flood risk analysis method used in reservoir flood operation are discussed, uncertainty factors influencing flood discharge risk are analyzed, and distributing function and parameters of stochastic variables are given. An exa- mple is given to calculate the flood risk probability that the protected downstream areas suffer, which is caused by reservoir flood optimal discharge process.

The state of risk management methods in flood control and hazard mitigation is reviewed.Hydrological risk analysis includes linetype selection,parameter estimation,risk rate calculation;studies of hydraulic risk place focus on flood discharge risk of reservoirs and flood routing of riverway and flood plains. Economic risk analysis centres on cost benefit risk analysis of flood control. Risk decision making resesrch involves reliability programming and multiobjective risk analysis.In the study of flood insurance mainly simulation model is used to deduce an optimal flood insurance policy. Finally, the tendency of risk management in flood control and hazard mitigation is described.

主要对水文风险、水力风险、经济风险、风险决策和洪水保险五个方面的风险管理方法在防洪减灾中的研究现状进行归纳和评述 .其中水文风险的研究重点分为线型选择、参数估计、风险率计算三部分 ;水力风险的研究主要集中在水库泄洪风险及河道或洪泛区的洪水演进研究 ;经济风险分析主要集中在防洪费用效益的风险分析 ;风险决策研究通常表现为防洪问题的可靠性规划和多目标风险分析两种形式 ;洪水保险的研究主要是利用模拟模型来推导一个最优洪水保险策略 .文末阐述了防洪减灾风险管理的发展趋势

In this paper, the effect of the uncertainty of the flood hydrograph on flood discharge risk is analyzed. Monte-Carlo method is used to calculate the flood discharge risk of an actual engineering project with consideration of the uncertainty of flood hydrograph,the result of which is compared with the that was calculated without consideration of the uncertainty of flood hydrograph. The comparison shows that the discharge risk of the latter one is obviously higher than...

In this paper, the effect of the uncertainty of the flood hydrograph on flood discharge risk is analyzed. Monte-Carlo method is used to calculate the flood discharge risk of an actual engineering project with consideration of the uncertainty of flood hydrograph,the result of which is compared with the that was calculated without consideration of the uncertainty of flood hydrograph. The comparison shows that the discharge risk of the latter one is obviously higher than the former. Therefore, the uncertainty of flood hydrograph can not be neglected in flood discharge risk calculating.

重点分析了洪水过程的不确定性对泄洪风险的影响,并通过假设检验得到了洪峰削减系数的概率密度函数。以实际工程为例,利用蒙特卡洛法计算了考虑洪水过程不确定性的泄洪风险值,并与不考虑洪水过程的不确定性的计算结果进行了比较验证,结果表明后者的风险值明显大于前者,说明洪水过程不确定性对泄洪风险的影响是不可忽略的。
