Re: On the problem that NO3 keeps accumulating and phytoplankton does not grow when running UMAINE 15 model

Hi, in the UMAINE15 model, phytoplankton can take up nitrogen both from NO3 and NH4. NH4 is generally preferentially used and the extent of this is governed by the parameters pis1 and pis2. you don't say what time level the maps of phytoplankton and nutrients are made, nor where the site for the ...

Re: Fluxes at sediment-water interface

hi all, i apologize for the vaguely worded "question" in my last post. let me follow up to share my newly-acquired understanding of the ANA_BPFLUX option. at least with the ROMS version i am using (v3.7), undefining the ANA_BPFLUX option causes the model to attempt to read bottom tracer fluxes from ...

Re: River bottom salinity too high

I have also encountered this problem of hypersaline water at depth near river inflow points. In addition to the suggestion that the inflow be specified (using Vshape) to be stronger at the surface, I have also found that making the water depth uniform in a small area around the inflow point helps to ...

Re: History file output fails using WRITE_WATER and river in

I delved a bit further into this problem and I think that I have found the source of the problem. I also have what I think is the solution. The problem: The run would fail when writing ubar because the program was attempting to write more ubar values than the history netcdf file was dimensioned for ...

History file output fails using WRITE_WATER and river inflow

Hi, i have encountered a problem when running ROMS version 3.7 that appears to be related to the use of the WRITE_WATER option in conjunction with the specification of river inflow (using LuvSrc). i am using the MASKING option and i specify the river inflow at a v-point that is masked as land (which ...
