RIVER ICE FREEZE-UP PROCESSES

River ice processes occured during the freeze-up period are studied. Freeze-up processes include frazil formation and evolution, anchor ice formation and growth, ice pan formation mechanisms and factors governing the types of freeze-up ice runs are not well understood. These processes have many engineering and ecological implications. The understandings on these processes are limited. Analytical and laboratory studies are carried out in this study.
