Abstract

Ice cover significantly modifies lake hydrodynamics, inhibiting wind stress, so correct modeling of lake dynamics during the ice-covered season requires accurate simulation of ice cover and its effects on heat and momentum transfer. In this study, applying the parallel AEM3D model (formerly ELCOM-CAEDYM), the ice-formation algorithm is a quasi-steady solution of the heat transfer equation for three layers (blue ice, white ice, and snow) coupled to the lake-mixing model. We will present results from recent simulations, in comparison to observed data. The implementation of an ice-cover routine will enable both winter and multiyear lake-management studies in regions subject to ice cover.
