Book Description
Scour data collected during 1989-1994 were evaluated to determine whether pier scour and contraction scour occurred at 22 bridge sites in Ohio. Pier-scour depths computed from selected pier-scour prediction equations were compared with measured pier-scour depths, and the accuracy of the prediction equations were evaluated. Observed pier-scour relations were compared to similar relations developed through laboratory research. Mean streambed elevations were evaluated to determine the depth of contraction scour. Channel stability was assessed by use of mean streambed elevations at the approach section. Ground-penetrating radar was used at all sites to investigate the presence of historical scour.

Book Description
The overall goal of this research was to improve MDOT's bridge scour prediction capability. In an effort to achieve this goal, the research team evaluated scour prediction methods utilized by state DOTs, conducted a field data collection project, and proposed an alternative approach for pier scour prediction. Nine locations and twelve unique spans were selected for monitoring. During the investigation, seven episodic measurements resulted in detectable pier scour. Scour depths ranged from 0.7 to 1.5 feet with the maximum return period corresponding to a seven-year flood event. No detectable scour events occurred at the continuous scour monitoring locations. This investigation also included the use of a Jet Erosion Test (JET) to experimentally determine if in-situ soil conditions could be correlated with measured bridge scour.

Book Description
Total estimated bridge scour was estimated at 833 bridges in South Dakota from 2003 to 2006 by the U.S. Geological Survey as required by the U.S. Federal Highway Administration.
