Sonar install at Youngs Bay Bridge
Detailed Description
The sonar equipment monitors streambed elevation near the bridge footing to measure scour depth. Accurately measuring scour depth is essential for evaluating bridge safety. During short storm events, crews may not arrive in time to monitor in real-time. Without continuous monitoring, the deepest scour could be missed if the hole refills before inspection.

Bridge scour monitoring in Oregon
The U.S. Geological Survey is working with the Oregon Department of Transportation (ODOT) and Federal Highway Administration (FHWA) to revolutionize bridge scour monitoring using real-time sonar data collection and bathymetric surveying to remotely monitor sites, collect long-term data for evaluation, and develop and improve hydraulic models that predict scour.
