Effects of Global Change on Extreme Precipitation and Flooding: New Approaches to IDF and Regional Flood Frequency Estimation

Abstract

The civil infrastructure of our country is by large built by stationary standards to address weather and climate related risks. However, with increasing effects of climate change being manifested, we are interested in re-assessing the risk of projects that are based on stationary intensity-duration frequency curves to manage events such as extreme precipitation and flooding via runoff. Our objectives are to (1) develop protocols for incorporating nonstationarity into extreme value theory, which can be applied to flood frequency as well as extreme precipitation events; and incorporate ongoing and future projections of climate warming on flood frequency estimates for watersheds affected by (2) rain-on-snow events and (3) atmospheric rivers.
