Effect of ship passage through an unconsolidated single-layer ice cover on ice jam initiation / by R. Carson.

Includes bibliographical references (page 19). "This study explores the effect of a ship on ice accumulated in a canal under normal flow conditions. Working rules have been established for the formation of a stable ice cover subjected to hydraulic forces in a canal. Pressures to permit ships to pass through a canal with developed ice cover require the assessment of the effect of ship passage on the ice cover. The results are relevant to the situation on the Beauharnois Canal where the production of electric power depends on the ice cover remaining in dynamic equilibrium. Navigation of the canal may cause ice jams resulting in loss of power production"--Introduction, page 1. Includes foreword and summary in English and French. Ice sheets Saint Lawrence Seaway.
