TRB will conduct a webinar on Monday, August 20, 2018, from 1:00 PM to 2:30 PM ET that discusses the Observation Method for Scour (OMS) tool. Bridge scour is the number one cause of bridge failures in the United States.  OMS addresses uncertainties in bridge design associated with bridge scour predictions by relying significantly on past observations at the bridge.

This webinar will present bridge scour case histories from Texas and Massachusetts where engineers used OMS; compare the predicted scour depths between OMS and current Federal Highway Administration guidelines; and compare the predicted scour depths to measured values. The presenters will also discuss the advantages and disadvantages of using OMS.

This webinar was organized by the TRB Standing Committee on Hydrology and Hydraulics and the TRB Standing Committee on Foundations of Bridges and Other Structures.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.
