Abstract:

The discrete element method provides an alternative to traditional analytical and experimental methods for studying river ice transport phenomena. In the discrete element method, the movement of each individual particle in the ice field is numerically simulated by taking into consideration mechanical interactions between ice particles, hydrodynamic interactions of ice and water, and the effects of various external forces. In this study, a two dimensional discrete element model is applied to the problem of ice transport and ice jam initiation in a straight channel reach with longitudinally varying flow depth and velocity.
