Last edition: '''[[Wikinfo(changed_ts)]]''' by '''[[Wikinfo(changed_by)]]'''

The PI is responsible to closely follow the progress of the action, 
and especially to contact NEMO project manager if 
the delay on preview (or review) are longer than the 2 weeks expected.

=== Description

{{{#!box width=25em 
Add drag due to unresolved tidal internal waves according to the scalar form proposed by Jayne and St. Laurent
(2001). A proxy for topographic roughness has to be provided for the drag formulation. \\ 
This is meant to improve barotropic tides if they are activated. Should act on the tidal component of the dynamics only, 
hence requires some kind of time filtering. \\

=== Implementation

{{{#!box width=35em help
Describe flow chart of the changes in the code. \\
List the Fortran modules and subroutines to be created/edited/deleted. \\
Detailed list of new variables to be defined (including namelists), \\
give for each the chosen name and description wrt coding rules.
