There is a large dynamic reservoir capacity in mountainous channel reservoirs,and inaccurate calculation of reservoir capacity can lead to large deviations in the formulation of reservoir scheduling.This article introduces the seg-mentation method based on the characteristics of reservoir water surface changes to segment reservoir and calculates the dynamic reservoir capacity with the hydrodynamic model for achieving fine calculation of the dynamic reservoir capacity.In response to the computational efficiency bottleneck faced by hydrodynamic models in real-time calculation of schedu-ling,a surrogate model based on RSMGU and RSLSTM is established.Taking the Three Gorges Reservoir as the re-search object,the dynamic reservoir capacity has increased by about 12% compared to the static reservoir capacity model calculated based on the water level storage capacity curve.Taking the#4 flood in 2020 flood season as an example,it is found that using the dynamic reservoir capacity method to calculate the reservoir capacity can reduce partial discharge flow and further enhance the flood control and profitability of the reservoir.Meanwhile,it is found that the RSMGU is more suitable as a surrogate model for hydrodynamic models.
