Do you want to model culverts in Delft3D Flexible Mesh? This is the current status.
Culverts transport water below a road or dike. This option is currently being developed and implemented for 2D and 3D simulations. In the meantime, there is a workaround: adding a 1D feature using Delft3D FM 1D2D.
The workflow involves several steps using the 1D2D Suite. Once you have installed it, open it and you will see that the GUI is very similar to the 2D3D, but with some different menu options.
1. Load your model.
2. Create a 1D element representing your culvert.
3. Add an element for connecting the 1D element to the 2D network.
4. Connect the 1D to the 2D network.
5. Export the model.
6. Remove storage nodes.
7. Modify gully properties.
