Re: River Input

Dear John, I want to run an idealized ice-covered lake with a homogenous salinity of 0 PSU (I did not add an ice model). The surface temperature was set to freezing point temperature, with an initial linear stratification within the water column to a temperature of maximum density at the bottom. My ...

Solar radiation warms my surface layers quickly

Re: River Input

Thank you for your thoughtful response.
I added solar radiation effects to the model, but I couldn't keep the surface temperature at 0 degrees throughout the entire model run. Is there any way to achieve this?

Re: River Input

Hi all, Thank you, John and Kate. I run a model with two river inflows. I added solar radiation effects to this model (#define SOLAR_SOURCE). I cannot run it because the model needs a forcing file (It works without river inflow). I defined #define ANA_SMFLUX #define ANA_STFLUX #define ANA_SSFLUX #de...

Re: River Input

Dear kate,
Thanks for getting back to me.
Are these phyton files on your GitHub?
I want to add some fresh water to my idealized lake. Adding several rivers is the best option. Can I add Qs? I cannot add a file like precipitation because it is an ice-covered lake.

Re: River Input

Dear John and Kate, Thank you for your reply. I added two rivers (using create_roms_rivers.m in COAWST m files) to my idealized ice-covered lake with a homogenous salinity of 14 psu. The surface temperature was set to freezing point temperature, with an initial linear stratification within the water...

River Input

Dear John,
I want to define a river in my idealized axisymmetric lake rather than as a point. I want to have distributed river input across the whole lake surface. Is it possible, or must I define it as source/sink points?

Best regards,
Fatima

solar radaiation

Dear all, I want to add The decay law for the flux of solar radiation in my model. As you know, it reduces with depth exponentially. I = I0 * e^(-k*d) where I is the intensity of solar radiation at a given depth in the water, I0 is the intensity of radiation at the surface of the ice, k is the atten...

Re: Signed Integer Overflow

Dear Arango,
Thank you for your answer. I am using gfortran and fedora (35) Linux. I did not change the definition. How can I solve the problem?
I have access to intel Fortran and a server. Do you think I should switch to the server and intel Fortran, or can I solve this problem?
Best regards,
Fatima
