Title: Scour Monitoring Programs for Bridge Health
Abstract: One of the most common causes of catastrophic bridge failures worldwide has been bridge scour, and in the United States this phenomenon accounts for more than 60% of bridge collapses. Scour monitoring programs that use sonar devices were developed for four bridges in the Northeast—three bridges on Long Island's South Shore in New York and the Woodrow Wilson Memorial Bridge over the Potomac River in Washington, D.C. These projects incorporated the sonar devices first recommended under NCHRP Project 21-3 and featured site-specific, detailed monitoring systems and programs for each bridge. This work included a series of firsts: a fixed sonar system installation for a tidal-cold weather environment, a multiple-station sonar system design with numerous innovative features, and a scour monitoring program manual. The scour monitoring program comprised investigation of the scour problem, consideration of countermeasure alternatives, analyses of pier stability, determination of scour critical depths, design of son...
