Short summary
In this study we propose using the equilibrium temperature approach to model complex heat transfer processes at the water–air interface in the SWAT model, which reflects the influences of air temperature, solar radiation, wind speed and streamflow conditions on the heat transfer process. The results indicate that the equilibrium temperature model provided a better and more consistent performance in simulating stream temperatures in the different regions of the Athabasca River basin.
