Abstract: A review of the mathematical models for river ice jams available in the literature is presented. All these models assume known the flow depth and the mean velocity immediately upstream from the jam leading edge, when in fact these quantities are themselves functions of the jam characteristics. Only the normal flow depth and velocity, and the channel characteristics are likely to be known. With these latter quantities as initial input, a numerical procedure for the prediction of the corresponding jam characteristics (equilibrium thickness, length of nonuniform reach, velocity of upstream propagation) is outlined. The assumptions contained in the proposed numerical procedure are discussed together with the areas where research both in the laboratory and in the field is, in the opinion of the writer, most urgently needed.
