Bridge scour is the removal of sediment such as sand and rocks from around bridge abutments or piers. Scour, caused by swiftly moving water, can scoop out scour holes, compromising the integrity of the bridge.

Bridge scour is one of the three main causes of bridge failure. It has been estimated that 60% of all bridge failures result from scour and other hydraulic related causes. It is the most common cause of highway bridge failure in the United States, where 46 of 86 major bridge failures resulted from scour near piers from 1961 to 1976.

Alexandre Gustave Eiffel

Gustave Eiffel (15 December 1832 – 27 December 1923) was a French civil engineer and architect. A graduate of the École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France. After his retirement from engineering, Eiffel concentrated his energies on research into meteorology and aerodynamics, making important contributions in both fields.
