SCOUR POWER

The leading cause of bridge failure is undermining of bridge foundations. Most equations to estimate scour at bridge crossings were developed from laboratory studies that used sand as the erodible medium. A new method for predicting scour in erodible rock that relates the erosive power of water and a geomechanical material classification system known as the erodibility index has been developed. This new method allows engineers to estimate rock scour and design cost-effective foundations and to better tailor pier design in rock and consolidated material.
