An academic report by Prof. Ting Fong May Chui


Prof. Cong invited Prof. Ting Fong May Chui to make an academic report on “The design of a sponge city – from technical optimization to social-economic analysis”.

Abstract: Conventional stormwater drainage system primarily focuses on flood control in urban regions and does not address the need of water quality management and ecosystem service design. Since the last decade, there have been rising interests worldwide in implementing component-based Best Management Practices throughout urban areas to promote sustainable stormwater management and to reduce environmental impact on receiving water body. This new approach in stormwater management, referred to as low impact development (LID) or sponge city, provide many benefits such as increasing freshwater supply and mitigating heat island effect in urban areas. Though gaining popularity worldwide, relatively less LID is found in megacities such as New York City and Hong Kong. The objective of my recent research is to evaluate the feasibility and also facilitate the LID implementation in megacities. It first applies numerical models and optimization tools to evaluate the effectiveness and also optimize the design of large-scale LID implementation. It further proposes specific techniques in greening existing drainage systems with LID practices given the unique conditions of megacities. LID implementation in highly urbanized environment is technically challenging, but also socially and politically complex. My technical research is therefore supplemented with social-economic analysis to justify and strategize such LID implementation.
