Abstract

Under excessive rainfall conditions, achieving Coordinated Regulation of Storage and Discharge (CRSD) across different regions can effectively reduce the overall risk of urban flooding. This study proposes three water gate control modes: no control, unified control, and independent control, taking the Lingang New Area as a case study, based on the differences in regional storage and discharge capacities, and evaluating the effectiveness of the three control modes through the model. The results show that both the unified control and independent control models significantly outperform the no control model in terms of total overflow volume control. When compared to each other, the unified control model is more suitable for overall drainage coordination across the system, while the independent control model is better suited for prioritizing the protection of specific regions, emphasizing the importance of identifying gate response thresholds.
