Flood Control Compensation Benefit Calculation of Large Reservoir

Flood control compensation benefit of reservoir aims at determining the relationship of the rights and obligations between reservoir and related target, and the scientific and rational calculation of compensation benefit of large reservoirs is necessary for Integrated Water Resources Management. In this paper, flood control compensation benefit of the Longyangxia Reservoirs is analyzed and computed. The result shows the compensation benefit of reducing investment for Longyangxia, raising the flood control standard of Liujiaxia Reservoir and upgrading the guaranteed rate of 100-year frequency flood are 54 million Yuan per year, 36 million Yuan per year and 29 million Yuan per year respectively. The flood control compensation benefit of Longyangxia reservoir amounts to 119 million Yuan per year totally.
