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. Typical ADCIRC applications have included:

• Prediction of storm surge and flooding
• Modeling tides and wind driven circulation
• Larval transport studies
• Near shore marine operations
• Dredging feasibility and material disposal studies

ADCIRC has been used around the world for various studies, including those conducted by the United States Army Corps of Engineers (USACE), Federal Emergency Management Agency (FEMA), National Oceanographic and Atmospheric Administration (NOAA), and many others.

Code versions are published based approximately on semantic versioning. Using the major version number (i.e. XX in the version XX.YY) will maintain solution consistency across minor version numbers except when there are critical bug fixes. Changes to the major version do not guarantee solution consistency, which may be due to improvements in the algorithm or other fixes. The general opinion is that the solution is improved in greater major version numbers and if exact consistency is required, it's recommended that the same major version is used. Note that other factors, including compiler versions and optimization may also impact solution consistency and the user should understand their compiler.

Documentation is presently undergoing upgrades, however, the main documentation locations for users are:

1. ADCIRC website
2. ADCIRC Wiki

The ADCIRC testing repository doubles as a set of examples which can be used for new users to become acquainted with the model. Since version 55, the branches are annotated with the expected version numbers that would allow the tests to run successfully.
