From July 11 to 12, the exchange meeting for the results of the national key R&D program project “Key Technologies for Assessment and Emergency Response to Derivative Composite Disasters in the Guangdong-Hong Kong-Macao Greater Bay Area”—specifically the topic “Composite Regulation of Flood Prevention and Saltwater Intrusion Supply, and Multi-Objective Optimization for Emergency Response to Composite Disasters”—was successfully held at the College of Habor, Costal and Offshore Engineering, Hohai University. The meeting was co-hosted by Vice President Zhang Wei and Vice President Yang Fang from the Pearl River Hydraulic Research Institute. Members from the leading organization, the Pearl River Hydraulic Research Institute, as well as participants from Sun Yat-sen University, Hohai University, and the Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) attended the meeting.

At the meeting, Professor Zhang Wei delivered the opening remarks, warmly welcoming all attendees. The project leader, Dr. Yang Fang, introduced the main content of the project, the completion status of key assessment indicators, and current main tasks, acknowledging the hard work and significant achievements of each sub-project team since the project commenced. Subsequently, the leaders of each sub-project reported on their respective research results, the status of assessment indicators, and future work plans: Professor Wang Xianwei from Sun Yat-sen University for sub-project 4.1, Associate Professor Xu Yanwen from our institute for sub-project 4.2, Engineer Wang Sengao from the Pearl River Hydraulic Research Institute for sub-project 4.3, Professor Tan Xuezhi from the Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) for sub-project 4.4, Dr. Zhang Yin from the Pearl River Hydraulic Research Institute for sub-project 4.5, and Engineer Hou Bing from the Pearl River Hydraulic Research Institute for sub-project 4.6.

Invited experts, including Professor Wang Zhili from the Nanjing Hydraulic Research Institute, Professor Kong Jun from our institute, and Professor Zhang Wei, provided professional evaluations of the results from each sub-project and offered suggestions regarding the connections between the various sub-projects. Based on the experts’ feedback, team members engaged in in-depth discussions about the innovative aspects of the research and communicated plans for further optimizing the integration of results across the sub-projects.
