Abstract
Scour or erosion of the streambed near the
foundations of a bridge is often referred to as "bridge
scour." Bridge scour is caused by the interaction
between turbulent flows induced by bridge structures
and the streambed. These turbulent flows erode the
streambed and cause scour holes. The Georgia Institute
of Technology and the U.S. Geological Survey (USGS),
in cooperation with the Georgia Department of
Transportation and the Federal Highway Administration
(FHWA), are conducting an investigation to improve
bridge scour predictions by combining field monitoring,
physical modeling in the laboratory, and three-
dimensional numerical modeling of bridge scour. By
integrating three-dimensional numerical modeling with
laboratory and field measurements, it is proposed that
some of the uncertainties associated with bridge scour
predictions would be significantly reduced.
