ADCIRC is a system of computer programs for solving time dependent, free surface circulation and transport problems in two and three dimensions. These programs utilize the finite element method in space allowing the use of highly flexible, unstructured grids. ADCIRC applications have included: prediction of storm surge and flooding; modeling tides and wind driven circulation; larval transport studies; near shore marine operations; and dredging feasibility and material disposal studies.
The ADCIRC model is used in real time decision support services for coastal and riverine hydrodynamics, tropical cyclone winds, and ocean wave modelling for public sector agencies including NOAA, FEMA, the Coast Guard, and the US Army Corps of Engineers, among others. Recent developments in ADCIRC’s real time automation system, the ADCIRC Surge Guidance System (ASGS), allow real time modeling of active flood control scenarios (manipulation of pumps and flood gates) for decision support during riverine floods and tropical cyclone events. During these events, the results can be presented to official decision makers with the Coastal Emergency Risks Assessment (CERA) web application, an intuitive and interactive tool that integrates model data with measured data to provide situational awareness across the area of responsibility. Specific regional applications include decision support with the ASGS/CERA system in North Carolina (Irene 2011), Louisiana (Mississippi River flooding in 2016), and during the 2017 hurricane season for Harvey, Irma, and Maria.
