Introduction: In a previous report, Dingman et al. (1967) developed a method for calculating the temperature profile of a cooling river below a source of thermal pollution and the length of ice-free reach which could be maintained by such a source. Computer programs were used to calculate heat-loss rates based on mean daily values of meteorological parameters and to numerically integrate a complicated heat-loss expression. The present paper describes a simplified approach to the same problem, in which heat loss is calculated as a linear function of the difference between water temperature and air temperature, so that the integration can be performed analytically. A simplified but fairly general procedure for calculating water-air heat-loss rates on the basis of air temperature, windspeed, solar radiation, and general atmospheric conditions is also presented.
