Professor Nigel Wright from the University of Birmingham visited IWHR and lectured on urban flood resilience on April 19, comparing the approaches taken by four countries – U.S., U.K., the Netherlands, and China – to reduce flood risks and build flood-resilient cities. Practices of computer-based natural flood management (NFM), including feasibility demonstration of NFM projects, development of gridded models, simulation of urban drainage systems, solutions for data scarcity, etc., were illustrated based on case studies in London, U.K., and Chengdu, China.
