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.
