# ocean_waves Section

This section configures **ocean wave forcing**, including **parameterizations**, **drag**, and **friction settings**.

---

 | `FroudeCoefficient` | Scaling coefficient for Froude diffusion (default: `1.+01`). |
 | `OceanWavesForcing_flag` | Flag to enable/disable ocean wave forcing (`TRUE`, `FALSE`). |
 | `parameterisation` | Parameterization for ocean waves (`MAC-WILLIAMS`, `LONGUET-HIGGINS`). |
 | `drag_flag` | Flag to enable/disable drag (`TRUE`, `FALSE`). |
 | `friction_flag` | Flag to enable/disable friction (`TRUE`, `FALSE`). |

 | `discretisation` | Discretization method (`UNSTRUCTURED`, `STRUCTURED`). |
 | `file_directory` | Directory for ocean wave forcing files. |
 | `file_format` | Format of ocean wave forcing files (`WW3_SG_NETCDF`, `WW3_UG_NETCDF`, `WW3_SG_NATIVE`, `WW3_UG_NATIVE`). |
