Description
Summary: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, mechanical cutters, jets, projectiles, heat and several other forms of ice management aids were reversed. Two concepts, one using a fixed underwater scoring device and the other using a mobable impactors on top of the ice, were in the final selection process. (Author)
