Urbanization and climate change are heightening the risk of rainwater runoff and flooding in cities, with flooding threats rising by 300-900% over the last 50 years due to global warming and sea-level rise. This challenge calls for real-time monitoring and innovative strategies to measure and manage flooding impacts. This research explores the use of urban digital twins (UDTs)-virtual city models combining data from BIM and IoT sensors-to simulate and analyze "sponge" public space designs that aid in stormwater management and flood mitigation. By testing various nature-based systems (NBS), like rain gardens, green roofs, and wetlands, within the UDT model, the study aims to identify the best solutions for rainwater absorption, groundwater recharge, and achieving Sustainable Development Goals related to clean water, climate action, and sustainable cities. The findings will offer urban planners and designers key insights into creating flood-resilient cities through sustainable, low-impact green infrastructure.
