Abstract: The purpose of this study was to develop a method for the calculation of temperatures in the St. Lawrence River for natural conditions before freeze-up and the forecast of the possibility of keeping the river channel ice-free in winter-time. The paper presents the analysis of hydrological, thermal and meteorological conditions for the investigated river section, calculation of the heat transfer coefficient, and the development of the method for the calculation of river temperatures. Verification of the method was based on data from field measurements. Three ways of improving the thermal conditions in the river were considered: an increase of discharge, a decrease of water surface by river training in the form of a regimented channel, and the utilization of waste heat from thermal or nuclear power plants.
