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 two nodestrings
 
* '''Weir''' – requires two 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.
