O článku:
Ice jams in rivers often arise from the movement of frazil ice as cover-load under ice cover, a process which is
conceptually similar to the movement of sediment as bed-load along a river bed. The formation and movement of an iceaccumulation
wave is one facet of a larger class of cover-load movements. The movement of an ice-accumulation wave
obviously plays a crucial role in the overall process of ice accumulation. In the present study, experiments under
different flow and ice conditions help reveal the mechanics of formation and evolution of ice-accumulation waves. In
particular, suitable criteria for formation of an ice-accumulation wave are investigated along with the resulting speed of
wave propagation. The transport capacity of frazil ice under waved accumulation is modeled by comparing those of
experiments collected in laboratories, and the resulting equation is shown to be in good agreement with measured
experimental results.
