Re: shallow water blow up due to large wind speed or too much cooling?

Thanks, John.
Yes. I checked and plotted his and rst file, looking normal.
When I turned on the wet_and dry flag, the model just passes that blow-up points.
May I know the reasons behind that?
Thanks

shallow water blow up due to large wind speed or too much cooling?

Hi all, I met a problem for model blowing-up in the form of outputting NaN in the log file with ROMS3.7. My model is used in temperate shallow-water estuarine systems in East US, the grid resolution is around 400m*400m, mean-depth is less than 9 meters. The model starts in Jan 1st-XXXX, and It blows...

Re: COAWST grid script help

Thanks John,
Problem solved by changing in
mat2roms_mw.m
line 93

projection = s.projection;
m_proj(s.projection);
switch lower(projection)

to
projection = s.projection;
m_proj(s.projection.name);
switch lower(projection.name)

ROMS processing water sluice in upstream

May I ask if ROMS could process this: Assuming I am going to model a lake and a river is in the upstream connecting the lake. But the river discharge was controlled by a water sluice, some times discharge is zero. So the water level in the late is influenced by that discharge. Could ROMS process tha...

Hi I am testing the lake Jersey nesting case. However, results did show same as in the. It is a constant temperature all the time.It might due to surface wind setting. May I know how to fix that by the analytical setting? Here is the log.file and also the my results and roms website results. Thanks....

ROMS mixed layer depth output

Hi All,
May I ask the possible and simple way for obtaining the ROMS mixed layer depth under GLS mixing scheme.
The ROMS only has surface boundary depth for application under LMD scheme, but that scheme mixes almost whole water column. Any suggestion?

Thanks

And it will consistent with ROMS has a pre3d_t.F routine, then it finally gets to step3d_uv.F and step3d_t.F. But when I ...

ROMS Lake Jersey ques

Hello All, I am going through this ROMS Lake_Jersey example. I have a very basic question, is this lake a real lake, since I see a lot of strong surface gradient in salinity and temperature? Could lake have so high-density gradient? Or this is just for a test case. Since I want to use ROMS for some ...

Vertical Salinity Profile in Estuary

Hello, I am modeling a vertical profile of a salinity in a estuary, depth around 25-30 meters. My case is that wind blow down-estuary, so the the pycnocline might be deeper, so the surface mixed layer might be about 12 meters according to measurement. But my model choosing a fix station did not full...
