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.

Modernizing Probable Maximum Precipitation Estimation
Consensus Study Report
·2024
For more than 75 years, high-hazard structures in the U.S., including dams and nuclear power plants, have been engineered to withstand floods resulting from the most unlikely but possible precipitation, termed Probable Maximum Precipitation (PMP). Failure of any one of the more than 16,000 high-haza...
