Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Laboratory tests were performed to investigate the properties of grounded ice accumulations. Two grounding mechanisms were identified. The first is by blockage, as described by Mathieu and Michel (1967). The flow through the grounded accumulation can be viewed as non-laminar seepage, where the seepage velocity is proportional to the square root of the water surface slope. The water level upstream of the grounded accumulation is governed by the no-submergence criterion for the incoming floes. The second mechanism results from the collapse of a surface jam, and the ensuing "snowball" effect may lead to grounding on arrival at the edge of a stationary ice sheet"--Abstract, p. i.
