Concept Development Program for Icebreaking on the Upper Mississippi River.
A number of concepts were considered for cleaning a channel in the Upper Mississippi River. All of those concepts considered feasible utilized an upward breaking bow of shallow angle in combination with a conveyor or system for placing cleared ice well back from the channel. The use of impact or, me...
