Abstract: Based on a (K-epsilon) model and using a finite volume, method, a model was developed to simulate the 2-dimensional velocity profile under ice cover. The comparison of the simulated results from this model with the measured data from experiments indicated that the data matched well with each other. The simulation indicated that the velocity profile varied with the roughness ratio between the ice cover and the river bed. The maximum velocity was larger for unequal roughnesses between the ice cover and the river bed than that for equal roughnesses between the ice cover and the river bed (symmetrical shape for velocity profile). However, the maximum velocity location only shifted within a limited depth range. The trend and value for the velocity profile simulated by this model matched well with those measured in the experiments.
