Abstract

A two-dimensional model was developed to study the effect of ice cover on the transportation competence of ice-covered flows. The model is based on the equations of motion, impurity transfer, turbulence energy, and the ratio of turbulent energy to turbulent kinetic energy with allowance made to the effect of turbulent energy bursts on solid surfaces bounding the flow. The turbulent bursts on solid boundaries of open and ice-covered flows are shown to have no effect on the structure of flows, characterized by their aver-aged characteristics, but considerably change the distribution of suspended sediment concentrations.
