Re: Flow runs to fast in ideal domain

It should be a good comment, since wave only transports energy, not for material as float. However, it raise me a question that, in order to convince the audience how float is transported in right way, it is had better to put figure of flow together. Although transport of float depend on several oth...

Re: Flow runs to fast in ideal domain

I set "undef" for all "FLOAT", "T-PASSIVE" and "SEDIMENT". Also I just ran ROMS alone, not coupling with WRF or SWAN.

Re: Flow runs to fast in ideal domain

It is really nice comment. I reduced depth the surface gravity wave speed decrease a lot.

However, in case I just only want to observe how flow base on the advection transport to other boundary. Could you kindly suggest me how to do that?

Thanks

Re: Flow runs to fast in ideal domain

Thanks for your comment.

The depth of my domain is 160 meter.

The vertical layers are 30. For simplicity, all layers have the same velocity. "no-slip condition was set.

I did not run with tide and all atmospheric forcing were set zeros.

Flow runs to fast in ideal domain

Hello everyone I did for ideal domain size with length of 200km in y, and 200km in x direction. The resolution is 3km x 3km. I put advection (source) at the left boundary with value of 0.4 m/s, while value in the inner domain are 0.1 m/s. Direction of current is only from left to right (u=0.4m/s at ...

Having problem with temperature and salinity of point source

Dear all, I want to see how temperature and salinity (T-S) transport from the point source. I turned on LtracerSrc == T T T, and putted temperature and salinity in the "river forcing NetCDF" with "river_flafg(river)=3 for whole depth column. The value of temperature and salinity are different with t...

Re: Problem during simulating sediment from point source

The flow rate is 0.01 m3/s. In my problem, the sediment concentration is quite high because it is released from mining activity. We may have 3 scenarios of releasing sediment from that with respect to the depth of release (at the surface (70m), middle (30m) or bottom). The location of sediment relea...

Re: Problem during simulating sediment from point source

I am so sorry for keep you waiting so long, because I was out of the office. I implemented the point source as a 1 river source. In order to constrain it stops after first 24 hours, I set the runoff equate 0 after first 24 hours. In addition, to release sediment at surface I only gave the value at l...

Hi. I simulated sand_01 transport from a point source (released only 24 hour) at the surface layer (25 layers with average depth around 70 m), sand_01 concentration of point source is 70 kg/m3, water discharge is 0.01 m3/s horizontal resolution in 6x6 km.

Re: ROMS & SWAN coupling: Subscript out of range for array d

Haizz. It is my mistake. I had typo in file "swan.in". The number "27" in line "INPGRID BOTTOM CURVILINEAR 0 0 156 27 EXC 9.999000e+003" must be replaced by 117 (it is horizontal grid point). Therefore, ROMS showed error with the "upper bound=28". I am so sorry for making you confuse above. Happy ne...
