Prediction of Water Temperature in Reservoirs

Zhu Bofang(Institute of Water Conservancy & Hydroelectric Power Research)  
Formulae are given for the prediction of Water temperature in reservoirs as follows:The temperature of the water at depth y and time τ: The yearly mean temperature at depth y:Tm(y)=c + (b-c)e-0.04y. ( 7 )The amplitude of yearly variation of water temperature at depth y:A(y)=A0e-0.018y. (11)The phase difference of water temperature at depth y:ε = 2.15-1.30e-0.085y (month). (12)Methods are given to. determine the parameters involved in these formulae.Results computed by these formulae agree well with those observed in reservoirs.
