Modernizing Probable Maximum Precipitation Estimation

Recently completed

Topics

This study committee will consider approaches for estimating probable maximum precipitation (PMP) in a changing climate, with the goal of recommending an updated approach, appropriate for decision-maker needs. PMP is commonly used in the design of critical infrastructure. The committee is charged with establishing a common understanding of PMP; reviewing and assessing existing approaches to PMP estimation and for incorporating the impacts of climate change on those estimates; assessing PMP data needs and sources; and recommending a preferred approach for PMP estimation that incorporates the impacts of climate change and the characterization of uncertainty.
