Scour or erosion-related processes account for most of the highway bridge failures in this country. While the situation is improving, because of a lack of field data a thorough understanding of the scour phenomenon is limited.

In DP-97, engineers, inspectors and maintenance personnel will be able to get a better understanding of how scour occurs and will get hands on experience using devices to measure bridge scour and monitor it's growth. Portable and fixed instrumentation, ranging from very simple to very sophisticated is demonstrated in a classroom setting. Opportunities for bridge sites visits and field installation of the instrumentation is available.

This activity, in conjunction with NHI Training Course No. 13046, "Stream Stability at Highway Bridges", is assisting the states in implementing the FHWA Hydraulic Engineering Circular "Evaluating Scour at Bridges" (HEC-18), 3rd edition, November 1995.

Since June 1996, DP-97 has been presented over 15 times. In addition to our traditional customers, the states, presentations have been made (and are available) to local municipalities, other Government agencies and as special sessions at conferences. To schedule DP-97, contact the Project Manager.
