Hello 

I hope this may help

Kind regards

Thank you for your answer.

I read these papers.

I think that we have 3 ways to describe the influence of Posidonia

1. Energy dissipation by vegetation has been implemented in version 7.0 of Tomawac

2. through friction coefficient Collins (use Collins coefficient for the bottom friction)

We need to change the code in Tomawac.

3. change bed rougness over Posidonia (bigger than sand, smaller than rock)
