Ice overtopping of embankments: ice-tank experiments and field observations
Ice-sheet overtopping poses a problem for embankments adjoining large water bodies in cold regions. The problem is akin to wave loading and overtopping, though the water level is well below embankment crest level. Wind drives ice sheets, imparting large momentum, causing ice sheets to severely impac...
