USGS National Hydrologic Model: Continental Scale Modeling for Decision-making, Research, and Education

Learn about the U.S. Geological Survey's National Hydrologic Model (NHM) Infrastructure in this conference presentation that explores comprehensive watershed modeling capabilities across the conterminous United States. Discover how this three-component system - featuring geospatial modeling units, climate forcing data, and physical simulation codes - bridges the gap between local engineering models and global land-surface models. Explore applications ranging from historical water budget simulations to near real-time natural water storage estimates, with specific examples from the Apalachicola-Chattahoochee-Flint River Basin and Southeastern U.S. Understand how this modeling infrastructure supports water resource management decisions, scientific research, and education by providing nationally consistent, locally informed data about streamflow, evapotranspiration, soil moisture, recharge, and snowpack across multiple spatial and temporal scales.
