Fresh water is one of our most valuable natural resources. Effective management of this resource is essential to ensure water availability.

Recent increases in extreme precipitation events both too wet and too dry further highlight the need for new and continued research into water and its impacts.

What We Do

PSL's Hydrology Applications Division transforms cutting-edge hydrologic science into actionable information for water resource management and infrastructure planning.

Using atmospheric and hydrologic models and observational data, we advance physical understanding and prediction of water availability and hydrologic extreme events, such as floods, drought, and wildfire, and provide reliable and use-inspired water resource information to stakeholders inside and outside NOAA.

This is accomplished by focusing our research in three distinct areas: Precipitation Processes and Extremes, Hydrometeorology Modeling, and Monitoring, Predictability, Prediction, and Projection.
