ABSTRACT
As has been explained, the heat budget equation (1) depends on different terms; some of them have some parameters we must determine if we want to analize the thermal behaviour of a river.
The water temperature at the beginning and at the end of the reach was directly measured, giving the values Ts and AT. The discharge of the river is known because of the existence of a measuring cross section at the begining of the reach (at Flix Power Station).
