High-performance, cross-platform numerical ocean circulation model
ADCIRC mesh in theChesapeake Bay area used for theFEMA Coastal Storm Surge Study TheADCIRC model is a high-performance, cross-platform numericalocean circulation model popular in simulatingstorm surge ,tides , and coastal circulation problems.[ 1] [ 2] [ 3] [ 4] Rick Luettich andJoannes Westerink ,[ 5] [ 6] University of North Carolina at Chapel Hill , theUniversity of Notre Dame , and theUS Army Corps of Engineers .[ 7] surface runoff , and baroclinicity.
The model is free, with source code made available by request via the website,[ 1] Fortran compiler . A pre-compiledWindows version of the model can also be purchased alongside theSMS software.[ 8] Fortran , and can be used with nativebinary ,text , ornetCDF file formats.
The model formulation[ 9] shallow water equations , solving thecontinuity equation (represented in the form of the Generalized Wave Continuity Equation[ 10] advective ,Coriolis ,eddy viscosity , andsurface stress terms included). ADCIRC utilizes thefinite element method in either three-dimensional or two-dimensional depth-integrated form on a triangularunstructured grid withCartesian orspherical coordinates. It can run in eitherbarotropic orbaroclinic modes, allowing inclusion of changes in water density and properties such as salinity and temperature. ADCIRC can be run either in serial mode (e.g. on a personal computer) or in parallel onsupercomputers viaMPI . The model has been optimized to behighly parallelized , in order to facilitate rapid computation of large, complex problems.[ 11] [ 12]
ADCIRC is able to apply several different bottom friction formulations includingManning's n -based bottom drag due to changes in land coverage (such as forests, cities, and seafloor composition), as well as utilize atmospheric forcing data (wind stress and atmospheric pressure) from several sources, and further reduce the strength of the wind forcing due tosurface roughness effects.[ 13] [ 14]
ADCIRC is frequently coupled to awind wave model such as STWAVE, SWAN, orWAVEWATCH III , especially in storm surge applications wherewave radiation stress can have important effects on ocean circulation and vice versa. In these applications, the model is able to take advantage of tight coupling with wave models to increase calculation accuracy.[ 14] [ 15]
