GenCade Model Capabilities
Jump to navigation Jump to search
GenCade has the following capabilities:
- Internal wave transformation module
- Arbitrary numbers of groins, detached breakwaters, beach fills & seawalls
- Almost any combination of structures & beach fills
- Bypassing & transmission of sand at groins & jetties
- Multiple diffraction from structures
- Multiple wave trains
- Wave transmission through detached breakwaters
- Tombolo development inside detached breakwaters
- Sediment transport from breaking waves combined with other currents
- Accounts for pre-specified stable regional or local contours
- Algorithm for variable, time-dependent transmission coefficient
GenCade can account for the vertical and cross-shore distributions of longshore sand transport at groins and jetties in an empirical fashion. It does not, however, account for the full vertical and horizontal water and sand circulation, making it incapable, for example, of describing transport by rip currents, undertow, or other three-dimensional transport processes.
GenCade incorporates the Inlet Reservoir Model (Kraus 2000) to describe sediment storage and transfer at coastal inlets. The user provides initial morphological unit (shoal) and equilibrium volumes for fixed hydrodynamic and sediment conditions.
