Nonstationary flood risk assessment in coastal regions under climate change
2021 Spring. Includes bibliographical references. Coastal cities are exposed to multiple flood drivers including high tide, storm surge, extreme rainfall, and high river flows. The occurrence of these flood drivers, either in isolation or in combination, can cause significant risk to property and hu...

2021 Spring. Includes bibliographical references. Coastal cities are exposed to multiple flood drivers including high tide, storm surge, extreme rainfall, and high river flows.
