The Hydrometeorological Section of the Weather Bureau has been engaged in a study directed towards a determination of maximum possible snow‐melt rates over selected drainage‐basins. Since snow‐melting is a thermodynamic process the investigation pertained largely to a consideration of the various factors influencing the transmission of heat to the snow‐mantle. Of these factors, it was found that for high melting rates the heat contributed by convection and condensation of moisture through turbulent diffusion of warm moist air are the important heat‐sources. The problem is, then, largely a consideration of the upper limit values of air‐temperature, humidity, and wind‐velocity compatible with an adequate snow‐cover, and the relationship of these values to the rate of snow‐melt.
