"September 1989." Includes bibliographical references. "This report is intended to become a part of a state-of-the-art report on environmental aspects of river ice. The river ice cover acts as a second boundary for the flow thus increasing hydraulic resistance and changing the velocity profile. The effects of the ice cover in the transport and mixing processes are discussed, in light of the altered flow field. The conventional concept of the two-layer, composite flow under an upper boundary provides good approximations if used judiciously. Major gaps in current knowledge exist with respect to scour caused by ice jams and to transport of coarse and fine sediments under an ice cover"--Abstract.
