| Much of ADCIRC's versatility as a model is due to the large number of different boundary types and boundary conditions available in the model.

| | |
| == ADCIRC Boundary Types ==
| |
| Boundary types are assigned to feature arcs in the conceptual mode or nodestrings on the ADCIRC mesh. Correct boundary type assignments are very important to run a successful ADCIRC project. The following boundary types are available in SMS for ADCIRC:
| |
| * '''Unassigned''' - default, no boundary condition assigned
| |
| * '''Mainland''' - land or coastline boundary
| |
| * '''Island''' - this can be selected for a closed feature arc
| |
| * '''Normal Flow''' - assigned across the nodes of the mesh, therefore the parameters of this boundary type can only be modified after a mesh has been created and the mesh module is currently selected
| |
| * '''Normal Wave Radiation'''
| |
| * '''Mainland Barrier'''
| |
| * '''Island Barrier''' - requires 2 nodestrings
| |
| * '''Weir''' - requires 2 nodestrings with the same number of nodes
| |
| * '''Zero Normal Velocity Gradient'''
| |
| * '''Ocean'''
| |
| | |
| == ADCIRC Boundary Conditions ==
| |
| Depending upon the specified boundary type, the following boundary conditions are available:
| |

| == Nodal Boundary Conditions (Recording Stations) ==
| |
| The following boundary conditions can be assigned to an ADCIRC mesh node:
| |
| ===2D Station Types===
| |
| * Elevation
| |
| * Velocity
| |
| * Concentration
| |
| * Meteorological
| |
| ===3D Staion Types===
| |
| * Density/Temperature/Salinity
| |
| * Velocity
| |
| * Turbulence
| |
| ===Description of Station===
| |
| Stations can be assigned a name to make station identification easier.
