Model description
| Model type: | Modular model for the coastal domain. |
| Description: | NearCoM predicts waves, currents, sediment transport and bathymetric change in the nearshore ocean, between the shoreline and about 10 m water depth. The model consists of a "backbone", i.e., the master program, handling data input and output as well as internal storage, together with a suite of "modules": wave module, circulation module and sediment transport module. |
Technical information
| Supported platforms: | UNIX, Linux |
| Programming language: | Fortran77, Fortran90 |
| Model development started at: | 1999 and ended in 2004. |
| To what degree will the model become available: | Source code will be available |
| Current license type: | GPL v2 |
| Memory requirements: | -- |
| Typical run time: | -- |
Input / Output description
| Input parameters: | See documentation. |
| Input format: | ASCII |
| Output parameters: | See documentation. |
| Output format: | ASCII |
| Post-processing software (if needed): | No |
| Visualization software (if needed): | Yes, Matlab |
Process description
| Processes represented by model: | NearCoM predicts surface waves and wave-induced nearshore processes such as nearshore circulation, sediment transport and morphological changes. |
| Key physical parameters & equations: | Wave equations, wave-averaged circulation equations and equations for bedload and suspended-load sediment transport. |
| Length scale & resolution constraints: | Nearshore regions from shoreline to 10 meter water depth. Model resolution depends on specific modules. |
| Time scale & resolution constraints: | Hours to months. |
| Numerical limitations and issues : | Wave modules have an automatic grid refinement feature. Circulation modules have two kinds: CFL limited and CFL-free schemes. |
