Short Summary

This study developed a simulation-optimization framework to optimize gate-pump operation for coastal plain river networks during typhoons. The framework reduced water-level exceedance by 68.1% compared to historical baseline operations.

Objective

• Develop an efficient and coordinated gate-pump operation strategy for the northern drainage river network of Yuyao City, China, during typhoon rainfall events.

Study Configuration

• Spatial Scale: Northern drainage river network of Yuyao City, China.
• Temporal Scale: 72 hours during Typhoon In-Fa.

Methodology and Data

• Models used: SWMM–NSGA-II simulation–optimization framework.
• Data sources: Historical rainfall data, tidal backwater data, and hydraulic structure operation records.

Main Results

• The final Pareto set contained 36 feasible non-dominated schedules with zero constraint violation (CV=0).
• Key findings:
  • Discrete quadratic water-level exceedance penalty index at the three control stations: 39.29 to 51.59 m2.
  • Total energy consumption of the three controlled pumping stations over the 72 h horizon: 914.15 to 1364.00 GJ.
  • Cumulative number of binary state changes of the controlled sluice stations and individual pump units: 184 to 256.

Contributions

• This study provides an original contribution by developing a simulation-optimization framework for coordinated gate-pump operation in coastal plain river networks during typhoons, which can be applied to similar regions with similar hydraulic conditions.
• The results highlight the distinct hydraulic roles of coastal and internal structures in regulating water redistribution and transmission.

Funding

• This research was funded by the National Natural Science Foundation of China (Grant No. 51809252) and the Zhejiang Provincial Key Laboratory of Water Resources and Hydroelectric Engineering.
