Abstract: Most existing models to simulate the vertical profile of flow under ice cover are either empirical/semi-empirical (1D only) or make use of sophisticated turbulence modeling. We propose here a new approach that combines the simplicity of traditional approaches with the flexibility to extend to 2D and 3D numerical modeling. It is based on the general turbulent viscous approach, combined with simple friction laws that generate non-zero slip velocity at the wall. We first present in this paper the concept of the method that is applicable to 2D or 3D numerical modeling. We then apply this method for the case of simple steady-state uniform flow under ice cover. Results from the model are plot against the experimental data obtained from laboratory experiments. Discussion follows to analyze the capabilities and future development of this approach.
