520 |a"The second year's ice observation on the lower Thames River are described and partially interpreted. Freeze-up commenced in December 1980 and breakup took place relatively early, during February 17-23, 1981. Extensive flooding occurred during the breakup period, owing to relatively large runoff and competent ice cover. Numerous ice jams formed within the study reach. Of these, the ones near the river mouth and near Louisville were the most severe. Interpretation of the season's data supported an existing theory of equilibrium jams and a recently developed conceptual model of breakup. A lack of theoretical background for non-equilibrium jams was noted and a need for studying conditions at ice jam toes was manifested"--Abstract.
