Urban flood adaptation planning for local governments: Hydrology analysis and optimization

Urban flooding damage is an increasing problem in cities worldwide and is only expected to become worse as urbanization and climate change continue. To prevent disasters and minimize loss of life and economic harm, government agencies have started implementing large-scale projects; however, budgetary constraints and overly optimistic designs have prevented the desired results. This study aims to prove that flood adaptation models using small-scale technologies can ameliorate the impact of torrential rainfall events. A new hydrology analysis model was applied to a district in Seoul, Korea that is prone to frequent floods. The results were encouraging and indicated the effectiveness of careful planning and urban design.
