SWMM-Based Assessment of the Improvement of Hydrodynamic Conditions of Urban Water System Connectivity


Scientific assessment of the hydrodynamic conditions of water system connection is of great significance and value in guiding the ecological construction of urban water system connection and building healthy river–lake relationship. Based on the advantages of SWMM in effectively simulating urban rainfall and surface runoff, a hydrological and hydrodynamic model was constructed before and after the implementation of urban water system connection project, and the model was applied to the analysis of rainfall and flooding processes in two recurrence periods of 5a and 10a after the implementation of urban water system connection in Pingyu County. The results show that the initial flow rate and velocity of river cross-section increased in the same recurrence period after the water system connection, the maximum increase of water exchange capacity was 115.56%, the peak flow rate and velocity were weakened and the peak time was lagged, and the hydrodynamic conditions were improved significantly.
