Abstract:
A method for aiding the prevention of ice jamming at a man-made structure, and lessening the force exerted on these structures in a body of flowing water wherein a plurality of side-by-side slots are cut in the ice cover prior to substantial melting of same thereby reducing the size of and lessening the strength of ice floes which form during seasonal warm-up which causes thawing and breakup of the ice cover.
