A one-dimensional mathematical model for predicting the distribution of thermal energy in a deep, stratified reservoir is developed and applied to Lake LBJ. The model takes into account heat transfer through the air-water interface, advection into and out of the reservoir, and advection and diffusion in the vertical direction within the reservoir. A comparison of predicted and observed temperatures profiles shows good agreement. To predict the physical effects of the thermal discharge from a proposed power plant on a region of Lake LBJ, the model has been modified to account for temperature gradients in the longitudinal direction in addition to the vertical. Although there are limitations to the use of this two-dimensional model, it is a good starting point for more refined analyses of the physical effects of a thermal discharge on a stratified reservoir.
