Pool Temperature simulation problem

[a0309449]

Hello,

The depth of my study area is 3-5m, and I divided it into 3 layers. But the simulated layer temperatures are almost the same and are the same as the air temperature. What parameters should I adjust?

In setting the model boundary conditions, a quantitative inflow and a variable temperature series are set upstream. An open boundary is set downstream, given a very small water level. How can I adjust the model so that it can simulate changes in water temperature in each layer.
Thanks.

Hi a0309449

Coefficients related to Vertical Eddy Viscosity and Diffusivity as attached below,

and one of the options as indicated by the arrow in the image below related to Horizontal Turbulence

can improve temperature stratification. However, I think you should check if the temperature series at the upstream boundary has been assigned correctly, or you can try dividing more layers to test the result.
Sincerely,
BMHoa
