Quantification Method of Operation Cost and Benefit of Reservoir Dam Considering Potential Dam Breach
For the problems of gradual aging of reservoir dams and increasing risks and operation costs,a model to quantify the comprehensive costs and benefits of reservoir dam operation considering potential dam breach losses was constructed. Firstly,the impact of potential dam breach was considered comprehensively,the interaction relation-ship between the cost and benefit influencing factors of reservoir dam operation according to the ISM theory was clarified,and the quantitative indicators of the comprehensive cost and benefit of reservoir dam operation were de-termined. Secondly,the degree of interaction between the factors was analyzed based on the DEMATEL method,which clarified the relative importance between each cost and benefit indicator. Finally,the comprehensive cost and benefit of reservoir dam operation with potential dam breach losses were calculated in combination with the techno-economic theory. The model was applied to a reservoir in China. The comprehensive cost and benefit of the reser-voir operation were calculated,and its economic benefits were analyzed. The results showed that the comprehensive cost of operating this reservoir was 7436200 Yuan while considering of potential dam breach losses,the compre-hensive benefit was 109118300 Yuan,and the benefit-cost ratio was 14.67. The comprehensive benefit of opera-tion was much larger than the comprehensive cost of operation,the revenue-generating capacity was good,and the economic benefits were significant.
