Urban river network waterlogging prevention optimal scheduling method
The invention relates to an urban river network waterlogging prevention optimal scheduling method. The method comprises the steps that basic data of all rainwater sub-catchment-areas on the upstream of an urban river network are acquired, SWMM models are constructed correspondingly, rainfall runoff simulation is conducted by inputting rainfall hydrographs, and discharge curves of rainwater pipe network drainage ports of all the sub-catchment-areas are acquired; basic data of an urban river network system is acquired, a river network SWMM model is constructed, the discharge curves, of the drainage ports, acquired in S1 are taken as inflow of the river network model, and the model is used for calculating a system overflow amount and a river and lake water level hydrograph under a specific scheduling strategy; a river network system waterlogging prevention optimal scheduling model is constructed, which comprises an optimized objective function and a decision variable, and optimization isconducted on the decision variable on the basis of a differential evolution algorithm; and coupling of the optimal scheduling model based on the differential evolution algorithm and the SWMM model isrealized in a Python environment, and an optimal waterlogging prevention scheduling strategy of a river network system is iteratively calculated. The method is good in robustness and high in reliability, and the obtained scheduling strategy is beneficial to exerting the regulation and storage capacity of the urban river network system in urban inland inundation.
