Bridge Pier Scour under Ice Cover

Bridge pier scour is a complex process, which influenced by many parameters, including the presence of ice cover around piers. To better understand influence on bridge scour, an artificial cover, equipped with either smooth or rough surface, was constructed and tested experimentally. The positioned surface water submerged to specified depths in order replicate floating fixed (pressurized) conditions, respectively. During each test, velocity profile collected beneath after three-dimensional scan bed compare resulting scour. It discovered that increased under all conditions. Furthermore, as deeper into flow, flow increased, greater resulted. For level submergence, yielded compared cover.
