Sediment Initialization file generation

Hai

I am just trying the coastal configuration just like the Vilaine case (for another river). In Vilaine case I see a file like sed_init.nc. Is there a way (Matlab script ot Python script) to generate this file as per the new coastal cofiguration? Searched in Matlab preprocessing tools and the Python preprocessing tools. Unfortunately nothing is seen for the sediment initialization. If someone has done CROCO simulation for a specific river case, which includes the sediment transport can definitely help me. Is there a way to get more information?

Hello,

Regarding the sediment initialization file for MUSTANG, there is currently no generic distributed tool to generate it from external sediment data.

For our applications, we use external datasets such as the SHOM sedimentology data:
https://diffusion.shom.fr/donnees/sedimentologie/sedim-mondiale.html However, we have not yet developed a documented Python script and integrated it into one of the distributed CROCO repositories. This is something we plan to do in the future.

The required format for the sediment initialization file is described in the CROCO documentation:
https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.modules.sediment_mustang.html#input-file-initialization-of-the-sediment-cover

Note that you can also use a CROCO restart file to initialize the sediment cover, for example from a previous simulation initialized with a constant sediment bed.

Regarding river sediment fluxes, you can find information about the required river input file here:
https://croco-ocean.gitlabpages.inria.fr/croco_doc/model/model.modules.sediment_mustang.html#input-file-solid-discharge-in-rivers

I hope this helps.

Hi Slegac

Thanks for the reply. I shall go through the links.
