Hydrology Laboratory

The Hydrologic Ensemble Prediction (HEP) Group leads research and development (R&D) of hydrologic ensemble prediction and data assimilation capabilities in support of operational hydrologic forecasting in NOAA/NWS and research-to-operation transition of new capabilities to the River Forecast Centers (RFC) and Weather Forecast Offices (WFO). HEP works closely with the other groups in the Hydrology Laboratory, the RFCs, and other collaborators in and outside of NWS.
