I had forgotten this page existed. Sandro and I used it for the Bevano River inlet on the east coast of Italy.

Re: about the wind in the coupling of roms and swan

SWAN still needs the grid, bathymetry, winds, and boundary forcing just like it was a stand alone run.

Re: How to diagnose blow-ups with wetting/drying

If it is a ROMS/SWAN coupled configuration try looking at the waves and stokes velocities. They may not depend strongly on the fine scale changes in the grid making it not very sensitive to smoothing the grid. If something is happening making the gradient in the waves high it might cause a blow-up b...

Re: Passive tracer in river forcing

The flags also extend to Sediment (flag=4), and I think potenially biology variables but I would have to go look in the code. The best thing to do is to look in the source code and see if there is a flag for a passive tracer. If not, it wasn't that difficult to add the sediment one you might be able...

Re: how to add sediment to the river?

It is like salt. Specify the suspended sediment concentration at each time-step, for each vertical layer, in each river. So, it should be a three dimensional matrix, although if only using one river one dimension will be length one. I copied my .cdl file below for reference. netcdf waipaoa_river.nc ...

Re: how to add sediment to the river?

Search the forum and the wiki for the correct cpp options to specify a point source (river) discharge for your application (you are right you should specify RIVER_SEDIMENT). The CDL file for creating the ROMS forcing file contained in the svn source code has some of the needed variables in it for an...

As preemptive info you may already know.

You will have to change all the line endings in all the files if you are not running it in Windows.

In Linux/Unix this can be done with the recode command.

Treatment of rivers

Is it our consensus that the best way to put freshwater in is as a surface plume instead of as a well-mixed layer?

I would have thought to put them in as a well-mixed layer with freshwater spread throughout all vertical levels.
