WebDuring thaws, runoff from snow melt increases the flow of water in rivers. This increased flow raises the water level, which pushes up on ice sheets covering the top of the river. If the ice sheets break apart, it moves downstream in a surge large ice chunks. In places of restricted water flow (such as shallow bends in a river, an intact ice ... WebIce production is then in balance with the rate of cooling occurring at the surface. The particles of ice in the flow are termed frazil ice. Frazil is almost always the first ice formation in rivers. The particles are typically about 1 millimetre (0.04 inch) or smaller in size and usually in the shape of thin disks.
