Evaluation of Ice Management Problems Associated with Operation of a Mechanical Ice Cutter on the Mississippi River.
Ice management problems associated with operation of a mechanical ice cutter for use in icebreaking as an aid to winter navigation are examined. The study concentrates on effects occurring after the cutting operation. Included in the evaluation are assessments of refreezing rates, movement and dispo...
