The Environment Agency has started a new project which aims to improve Probable Maximum Precipitation (PMP) and Probable Maximum Flood (PMF) estimation for reservoir safety.

The project aims to assess the suitability of existing methods for estimating PMP and PMF and develop new methods and guidelines to ensure that we understand the risk posed to our highest risk reservoirs from extreme flood events. You can find further details here.

The project has two phases. This first phase aims to review options for alternative approaches to PMP and PMF estimation and recommend a way forward for development and implementation in Phase 2.  Phase 1 started in November 2020 and will take around 12 months to deliver.
