Partial Abstract: The problem of predicting downstream changes in river temperatures due to the addition of various forms of thermal pollution can be expected to assume greater importance as man increasingly uses river water as a coolant and as a medium for transporting biological wastes. A possible result of such pollution is the maintenance of ice-free river reaches during the winter which might have beneficial consequences to river traffic on navigable waterways. Previous methods for predicting downstream temperature decrease, which could be used to estimate lengths of ice, free reaches, are limited in that only a few of the several pertinent meteorological factors determining heat loss rates are considered. This report formulates a differential equation for the steady-state heat balance of a volume element of a river.
