Abstract

Bridges that traverse streams or rivers are susceptible to degradation or collapse due to riverbed erosion (i.e. “scour”) around bridge-supporting piers. Erosion is induced by rapidly moving currents that accelerate as they pass the piers. It is usually studied in small-scale experiments in laboratory flumes with a layer of sand placed on the flume bottom. However, wide piers are difficult to study in this…
