To predict storm surge water level and help control the impact of storm damage, experts in hydrodynamic engineering at the ERDC Coastal and Hydraulics Laboratory (CHL) helped to develop the ADvanced CIRCulation Model (ADCIRC). Certified by the Federal Emergency Management Agency (FEMA) for use in performing storm surge analyses, ADCIRC is a hydrodynamic modeling technology that conducts short- and long-term simulations of tide and storm surge elevations and velocities in deep-ocean, continental shelves, coastal seas, and small-scale estuarine systems.
