ADCIRC: Advanced Circulation Model

Type of Model: Finite Element Hydrodynamic Model for Coastal Oceans, Inlets, Rivers and Floodplains
First Released: June 21, 2007
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 and therefore can be run on highly flexible, irregularly spaced grids. Typical ADCIRC applications have included: (i) modeling tidally and wind driven circulation in coastal waters, (ii) forecasting hurricane storm surge and flooding, (iii) dredging feasibility and material disposal studies, and (iv) larval transport studies.
ADCIRC incorporates the following features:
      Use of Cartesian or spherical coordinates
      2DDI and 3D mode
      Full wetting/drying elements (2D and 3D)
      Barrier elements (e.g. levees)
      Conduits and porous barriers
      Harmonic analysis ("on the fly")
      Cold or hot starts
      Well documented with web-served user's manual
      Model design criteria
      Large domain - localized resolution strategy to simplify often very difficult boundary condition specification
      Very low numerical damping model allows model parameters to be based on physically relevant values
      Consistent with the governing equations
      Runs on single processor computers and parallel computers using MPI
      Ascii and NetCDF output formats
