New stress computation for non-cohesive sediment + diffusive-dispersive transport + Brush&Wolman validation case

Reference issue

None

Description

This MR is related to the developments proposed by IMFT/MFEED :

• A new scheme for effective stress computation for non-cohesive sediment is available with the following keyword (activated by default) :

  FROUDE SCHEME FOR EFFECTIVE STRESS = TRUE

• Diffusion for suspension have been corrected with new diffusive-dispersive law and associated coefficients :

  SAND DIFFUSIVE COEFFICIENT = 0.0

  SAND DISPERSION COEFFICIENT = 0.0

• New validation case Brush & Wolman

All Merge Requests:

• Update NEWS.txt to describe your changes.
• Run compile_telemac.py --check to check FORTRAN coding conventions.
• Run pylint to check Python coding conventions.
• If you added new files, run compile_telemac.py --clean --rescan and commit the updated cmdf file(s) accordingly.
• Run compile_telemac.py --clean for both normal and debug configurations.
• Run validate_telemac.py for both normal and debug configurations.
• Run validate_telemac.py --notebook for both normal and debug configurations.
• Run doc_telemac.py if there are any modifications in the documentation.
• Run damocles.py --eficas if there are any modifications in the dictionaries.

In addition, for a new feature:

• Check that your feature works in both serial and parallel modes.
• Add at least one test case to check the functionality (with documentation, graphics and VnV script)
• Update the documentation for the module in which your feature will be available.
