If simulated water temperature is like this, how to calibrate it?

In two figures below, you can see that simulated water temperature is not so “same” as the observed one. I use Equilibrium Temp (CE-QUAL-W2 Method). My active module is Hydrodynamics and Temperature. Could you give me some advice about calibrating the water temperature? (The water level’s simulation result is good)

I would recommend you to look at the aser.inp file where the temperature model takes the rainfall and evaporation rates.Other is to look at the wind BC.
