"This manuscript summarizes lecture notes presented partly at the IND Training Seminar on "Hydraulics of Ice Covered Rivers and Ice Jam Analysis", June 14 and 15, 1982, Hull, Quebec. The seminar was organized by water Planning and Management Branch Environment Canada, Ottawa, Ontario." Includes bibliographical references (pages 41-43). "Part I of this report deals with the "Hydraulics of Ice Covered Rivers". First, a brief review of basic concepts of open channel flow is given, leading to the various hydraulic resistance relationships and definitions of the associated coefficients. Extension of these concepts to flow under an ice cover is presented next, leading to composite hydraulic resistance relationships and coefficients; values of the latter for different ice cover types are reviewed. A brief discussion of the effects of a moving cover on flow depth is included. Part II of the report is entitled "Breakup and Ice Jams". In this part, a qualitative description of ice breakup, jamming and means of alleviation of their effects, is followed by a review of possible procedures to predict potential stages caused by ice jams"--Abstract.
