To address the issues arising from the Haihe "23·7" basin-level severe flood, and in response to the actual needs of the Tianjin Municipal Water Affairs Bureau's flood control scheduling work, this initiative follows the overarching principles of "demand-driven, application-first, digital empowerment, and capacity enhancement." Focusing on digitalization, networking, and intelligence, and guided by the paths of digital scenarios, intelligent simulation, and precise decision-making, the project aims to build and optimize the flood control data infrastructure, flood control model database, and flood control knowledge base on the foundation of a unified water resources map. Additionally, it seeks to enhance relevant information infrastructure capabilities. The goal is to establish an emergency command platform for flood control scheduling in Tianjin, with "four preemptive" functions, which will improve the scientific, precise, and efficient decision-making and management capabilities in flood control scheduling. This will provide strong support and drive the high-quality development of water resources in the new phase. This project is closely related to "WSIS C6: Enabling Environment" and "WSIS C12: ICT applications: E-environment", The model used in the project can be replicated to other regions of the world, and the project is sustainable.

Geographically, it is replicable; by building a flood control scheduling emergency command platform, it achieves functions such as rainfall sensing, flood control scheduling, and emergency command. Since cities, rivers, basins, and reservoirs around the world may face similar situations, the mature solutions of this project are necessary and feasible for application in other regions.

Technologically, it is replicable; the Tianjin Flood Control Scheduling Emergency Command Platform makes full use of cloud computing, digital twins, big data, and other technologies. The platform architecture is advanced and meets the requirements of technological development. Its technical system, system architecture, data structure, hardware and software selection, as well as its construction and service provision processes, comply with relevant standards. In the global water resources field, it can provide a wealth of experience for reference, demonstrating strong replicability.

In terms of applicability, it is replicable; the project covers key flood control scenarios in Tianjin, such as the Haihe main river’s primary channels, flood retention areas, Yuqiao Reservoir, and central urban areas. For water conservancy infrastructure construction in other regions, the project can serve as a reference not only for individual scenarios but also for complex and diverse composite scenarios.

Tianjin is located at the lowest reaches of the Haihe River basin, where multiple water systems converge and flow into the sea. Historically, the Haihe River basin has frequently suffered from flooding disasters, making it one of the regions most severely impacted by such events. In the future, continuous monitoring and governance will be carried out in this area.

This project leverages advanced and reliable technologies such as cloud computing, digital twins, big data, and artificial intelligence to ensure its robustness. The system can operate for many years without additional investment, allowing for the expansion and development of more twin environments based on the existing system, thereby achieving more effective monitoring and scheduling.

This project is closely related to "WSIS C6: Enabling Environment" and "WSIS C12: ICT applications: E-environment", It will promote collaboration between the water conservancy, environmental protection, and information infrastructure industries in areas such as flood disaster prevention and water resource management. Flood disasters often pose severe risks to people's lives and property, and Tianjin is located in a high-risk flood zone. The long-standing and ongoing important issue is how to manage flood disasters and reduce disaster risks. This project makes full use of ICT technologies to establish a monitoring and perception system focused on flood control scheduling, a digital twin model, flood control applications, and information infrastructure. It effectively covers all water-related services in the Haihe River basin of Tianjin, fundamentally reducing the likelihood of flood disasters.
