Modelling and Planning Strategies for Storage-Discharge Balance to Enhance Pluvial Flood Resilience in Flat and Sloping Areas 1: University of Innsbruck, Innsbruck, Austria; 2: China Academy of Urban Planning and Design, Beijing, China; 3: Delft University of Technology, Delft, the Netherlands; 4: Deltares, Delft, the Netherlands; 5: IHE Delft Institute for Water Education, Delft, the Netherlands Storage and discharge are two fundamental solutions to strengthening pluvial flood resilience. However, the “imbalanced” combination of the two measures in practice raises concerns in hydrologic, economic, spatial and social aspects. This research aims to quantify the balanced relationship between storage capacity and discharge capacity (SDB) for pluvial flood protection and provide planning strategies for different urban topographies. We suggest and apply a quantification method using different modelling tools -hydrological and hydrodynamic model- in two cases with distinct physical and socio-economic characteristics: one in flat polder area in Nanjing, China, and the other in a sloping hilly area in Feldbach, Austria. By means of comparative analysis of these cases, insights are gained into the modelling methods, results and proposed strategies for each context. The novel approach and findings of the case study provide valuable guidance for other cities and urban areas around the world to perform similar analysis before setting targets for long-term flood resilience planning. | |
