Ocean Modeling Discussion

Hi- I run the model with changed step3d_uv.F 1. I add USE mod_scalars for tdays !*********************************************************************** SUBROUTINE step3d_uv (ng, tile) !*********************************************************************** ! USE mod_param USE mod_coupling USE mod ...

Thanks!
I try to change some part in step3d_uv.F as you recommand!
And tell you how it works!!

Hi- I tried to use different vshape in a river_input file The result shows in the attached file..... (top: contour of salinity, mid : mass transport of low discharge, bottom : mass transport of high discharge/xaxis:days) I think only high discharge is read in the model. As I told previous topic, I ...

Okay, I can run the model with this river input.
And tell you whether it works or not!
Thanks

Thanks for your response I think I need to explain more about my study site. My estuary has a radial type gate(You can see attached picture). During dry season, the dam is closed. But it makes excess water overflow from surface. During flood season, the dam is opened from bottom. I wanna run my ...

Hi- I'm dealing with river discharge from dam My dam changes the vertical location of discharge according to mass transport. In order to represent it to my modeling, I Make multiple river files which have different river_Vshape value but has same Xposition & Yposition. So I put this information in ...

Hello all; I'm trying to coupling ROMS & SWAN in COAWST. But I got segmentation error like this. [jchang@plumeri Project]$ ./try.sh 0: Subscript out of range for array globalsegmap_g (waves_coupler.f90: 341) subscript=1, lower bound=0, upper bound=-1, dimension=1 I realize that It is related with ...

Sorry, I'm still confused with this.
When I turn off SWAN_MODEL, MCT_LIB in my header file,
I can compile ROMS ONLY with same mpi path(lib, include).
But if I just define SWAN_MODEL & MCT_LIB, it can't(No change in other things).

Thanks for response- Before this trial, I use just ROMS only. But I wanna do coupling ROMS & SWAN in this trial. When I was in just ROMS only, this mpich path didn't give errors and complete compiling. So 1. When I am coupling, Should I use openmpi instead of mpich? 2. Does it have any possibility ...

Hi friends- I'm trying to compile COAWST(ROMS-SWAN coupling). so 1. I compiled MCT which is in COAWST trunk with gfortran and I got lib, include directories. 2. I set my own cpps in header file (attached) 3. In order to compile COAWST, change Linux-pgi.mk in trunk (using pgi) 4. Change build.bash ...

Hello friends... I'm dealing with tide phase, so I wanna adjust time reference. There are three values related with time reference & tide in 'ocean.in' file. In my case, tide has reference time 2014-12-01 and Model simulation start time has same date. So I'll put Dstart = 16993(Modified julian date ...

Hi friends~ I'm trying to make model using different two model(Delft 3d, ROMS)at same estuary, and compare the result. for this,I want to change 4 things in ROMS(Horizontal eddy viscosity/diffusivity, Vertical eddy viscosity/diffusivity) to let same condition with Delft 3D. I look into ocean.in, and ...

I think, the reason why my transport shows alternatively zero and non-zero is the presence of dam.
And your comment means that my model read river_time value as in days???

Hello friends I have a problem with my river discharge. I have one big river in my estuary. and I set my own river discharge file. But when I run my model(river discharge + tide),it doesn't show any change in salinity though it read my river values according to my log file. Is there any problem in ...

Thanks kate!

I'll pick -15m.
How about Dcrit??
In my log file, Dcrit means Minimum depth for wetting and drying(m).
Is it value of minimum depth of wet point??

Hi friends! I'm modeling my own estuary in South Korea. And there are permanent wet(water) regions, permanent dry(land) regions, and alterable regions which depend on tide. In order to depict them. I will use 'wet_dry'. I have bathymetry data in permanent wet points and alterable points. But how can ...

I always thank for your reply, Kate. I think, DX(DZ) problems occur because my grid file didn't have domain length and get negative value of bathymetry data. So I revised grid data and blows up in 2nd step. this error has been seen many topics in forum. So I try to run the model in short time step ...

Hi friends~~ I have same problem. In my case, I wanna start with stable condition. So I set all values(u,v,ubar,vbar,zeta) as zero except salt(32 psu), temp(10 Celcious)in initial condition. and set same condition in boundary file. These values can occur error??? I attach my log file for model ...

Thanks a lot!

hi everyone~ I set my grid file, initial condition file, tidal forcing,river discharge file. and I'm trying to run my model. But my model requires me to offer sustr & svstr though I'm not utilize any climate condition like wind. Then should I sustr and svstr in initial file as zero value??? or Are ...

Thanks kate.

How about values of Vtransform=2, Vstretcing=4, theta_s=0, theta_b=0, Tcline=0 ????

Hi friends~

I wanna get regular vertical grid for my model. In order to do that

1. I'll set Vstretching=1, Vtransfom=1, theta_s=0.0001, theta_b=0, Are they okay??

2. Should I put s_rho, s_w, Cs_r, Cs_w values in my initial condition file???

Thank you.

Hello friends I wanna make tide forcing in my model. I just have tide constituents(M2,S2,K1,O1,N2...) at open boundary. And as long as I know, there are two ways to force with tides. One way is to provide boundary conditions with enough temporal resolution to solve the tides and Second is to provide ...

Thanks a lot Kate
Your advice about grid was very helpful to me!

Thank you kate~
I'm trying to calculate dndx/dmde and angle by using matlab~~
but In case of mask, where can I find mask edit tools using matlab???

Hello friends~~ I'm new ROMS user I have Delft3D model inputs, so I wanna convert them to be able to use in ROMS. I'm dealing with grid, and I changed Delft3D grid into NetCDF file by using Delft3d-QUICKIN GUI. BUT I have several prombles.... 1. My Delft3D grid is cuvilinear. But my NetCDF file ...
