MULTIVARIATE COASTAL FLOOD RISK ALONG THE US PACIFIC. (2023). Coastal Engineering Proceedings, 37, management.60.


Urban coastal flooding is an increasing humanitarian and socioeconomic hazard. Flood assessments do not typically consider multivariate (marine and hydrologic) and multi-pathway (e.g., precipitation-surge, overtopping- overflow, surface–sewer) flooding, which may amplify coastal hazards and vulnerability. Notably, flood extent is underestimated when compounded hydrologic and marine impacts are not considered (Chen and Liu, 2014). Previous multivariate flooding studies typically consider the joint impacts of storm surge and fluvial sources. This study explores multivariate flooding caused by marine water levels, precipitation, and waves along the U.S. Pacific Coast while considering uncertainties in data sampling, precipitation source, record length, and distribution selection impart on risk estimates.
