Description
Technical field [0001] The invention relates to the technical field of optimized dispatching of water resources and reservoirs, and more specifically it is a method for verifying the calculation accuracy of storage capacity. Background technique [0002] The storage capacity curve of large reservoirs is the basic basis for the operation and management of reservoirs. The change of storage capacity directly affects the balance of water volume during flood regulation, and is related to the long-term benefit of the reservoir. In order to calculate the reservoir capacity and obtain the reservoir capacity curve, there are now a large number of measures aimed at storage capacity. Research on calculation methods; According to the classification of reservoir types, storage capacity curves are divided into static storage capacity curves for lake-type reservoirs and dynamic storage capacity curves for large river-type reservoirs. [0003] According to the different complexity of reservoir top...
