Abstract
This comprehensive study investigates the impact of extreme precipitation on flooding and the effectiveness of various mitigation strategies under both historical and future climate conditions, with a focus on an urbanized watershed and an environmental justice community in the vicinity of Philadelphia, Pennsylvania, USA. Utilizing hydrologic and hydraulic models, including both 1D and integrated 1D-2D PC-SWMM frameworks, the research examines the influence of spatial rainfall distributions and engineered drainage systems on simulated flood predictions. Through a detailed analysis of recent extreme precipitation events and specifically Tropical Storm Isaias, the study contrasts the accuracy of flood simulations based on differing rainfall data sources and drainage system representations. Findings indicate that radar rainfall datasets and skeletonized models of drainage networks provide more accurate predictions of flood risk, extending depths, and durations. Further, the paper explores the effectiveness of different adaptation approaches--resistance, nature-based, and community-driven--in the Eastwick community, assessing their performance against compound climate challenges, including increased precipitation and sea level rise. The research highlights the importance of integrating multiple modeling approaches and stakeholder engagement to develop resilient flood risk management strategies, thereby offering valuable insights into enhancing urban landscape resilience in the face of climate change and urbanization.
