Assessing Socio-economic Impacts of Compound Flooding for U.S. Coastal Communities

q Flooding, the most frequent and costliest natural disaster in the United States, incurs over $32 billion in annual losses.These losses are expected to rise by 26% in the next 30 years under RCP4.5 (Wing et al. 2022).q Recent studies show a rise in compound flooding events, involving storm surges, heavy rainfall, and high river discharge, especially in coastal areas due to climate change effects (Naseri & Hummel 2022; Bevacqua et al 2020).q Prior research, oTen focusing on single flood drivers and using staUsUcal models, has generally failed to fully capture the complex interacUons and cumulaUve impacts of mulUple concurrent flooding drivers.
