It is also possible to generate astronomic boundary conditions for Delft3D-FLOW with Delft Dashboard. The basic procedure to generate boundary conditions will contain of 4 four steps. The master function of this routine is ddb_generateBoundaryConditionsDelft3DFLOW.

4) Roughness
Delft Dashboard also supports to possibility to apply a different roughness on land than on the seabed.The basic procedure only contains three steps. The master function of this routine is ddb_ModelMakerToolbox_roughness.
1) All the relevant variables (grid, bathymetry, number of boundaries and source) are loaded from the interface in Dashboard (getHandles).
2) Determine which cells are above the land elevation defined. Grid cells above this value will get a land roughness and the remaining cells will get a sea roughness.
