Bridge-scour instrumentation and data for nine sites in Oregon, 1991-94

August 1, 1996

This report is a compilation of bridge-scour instrumentation information, bridge-scour data, and hydraulic data for nine sites studied in Oregon from October 1991 through September 1994. The Alsea Bay scour monitoring site was established to test new bridge-scour monitoring equipment, whereas the eight additional sites were established to monitor scour-hole elevations around piers and footings. These data were collected in cooperation with the Oregon Department of Transportation.

Sonar depth sounders, scour chains, and scour detection arrays were tested during this study; however; all of the bridge-scour data collected were from sonar scour-monitoring devices. Scour was observed at three sites during the period while the nine scour-monitoring sites were in operation. Work on the project is continuing, and includes testing of new scour-monitoring devices in addition to bridge-scour data collection.
