Abstract:
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 relationship 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 determined. 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 technoeconomic theory. The model was applied to a reservoir in China. The comprehensive cost and benefit of the reservoir operation were calculated, and its economic benefits were analyzed. The results showed that the comprehensive cost of operating this reservoir was 7 436 200 Yuan while considering of potential dam breach losses, the comprehensive benefit was 109 118 300 Yuan, and the benefit-cost ratio was 14.67. The comprehensive benefit of operation was much larger than the comprehensive cost of operation, the revenue-generating capacity was good, and the economic benefits were significant.
