Resilience effect of decentralized detention system to extreme flooding events

Abstract The experiences from recent urban flooding events suggest that the conventional centralized detention systems based on size expansion with minimum costs need to accommodate extreme exceeding their design capacity. This study investigated resilience effects of decentralized address in areas. An integrated flood measure integrates regional performance sub-basins a control system was proposed and applied an watershed including five sub-basins. Hydrologic hydraulic analysis quantify hydrologic responses scenarios performed using Hydrological Modeling System Geospatial River Analysis Engineering Centre models. results identified best locations distributed ponds characterized decentralization levels enhancing events. Additionally, increase found cases more combined impacts high-intensity rainfall land cover change. findings insights into incorporating strategies decision-making resiliently cope watersheds.
