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:
| Boundary Condition | Boundary Type |
|---|---|
| Essential w/ Tangential Slip |
Mainland Island Normal Flow Mainland Barrier |
| Essential w/o Tangential Slip |
Mainland Island Normal Flow Mainland Barrier |
| Natural (w/ Tangential Slip) |
Mainland Island Normal Flow Mainland Barrier |
| Tidal Constituents | Ocean |
| Curve | Ocean |
| Extract from Dataset | Ocean |
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.
