TechTalk – Urban Water Security and Smart Management in a Changing World: Case Study in the Yangtze River Economic Belt

February 24, 2025 (Monday) 10:30-11:30pm
Under the impact of global climate change, tremendous land use land cover changes, and extensive human interventions, urban areas face grand challenges in water security and green development. Ensuring urban water security requires ensuring quality and quantity of drinking water, sanitation, human well-being, water productivity, socio-economic values, ecosystems and environmental health, and mitigating water-related hazards. To resolve urban water security-related issues, a systematic framework by linking natural and social water cycles is urgently needed. Xia proposed the “Urban Water System, version 5.0” featuring “water quantity-quality-ecology” system approach by linking urban systems with natural river basin systems and applied it to the smart basin management, flash flood forecasting, and disaster mitigation. Besides, Xia led the development of the “Yangtze River Simulator,” which integrates sky-to-ground monitoring and comprehensive numerical simulation of hydrological-related processes in the Yangtze River Basin to foster the early warning and decision making of water security and water governance.
