The purpose of this PDH or CE course is to identify and provide design guidelines for bridge scour and stream instability countermeasures that have been implemented by various State departments of transportation (DOTs) in the United States. Countermeasure experience, selection, and design guidance are consolidated from other FHWA publications in this document to support a comprehensive analysis of scour and stream instability problems and provide a range of solutions to those problems. The results of recently completed National Cooperative Highway Research Program (NCHRP) projects are incorporated in the design guidance, including: countermeasures to protect bridge piers and abutments from scour; riprap design criteria, specifications, and quality control, and environmentally sensitive channel and bank protection measures. Selected innovative countermeasure concepts and guidance derived from practice outside the United States are introduced. In addition, guidance for the preparation of Plans of Action (POA) for scour critical bridges has been expanded to include a standard template for POA and instructions for its use.
How to Counter Bridge Scour and Stream Instability

Scour and stream instability problems have always threatened the safety of our nation’s highway bridges. Countermeasures for these problems are defined as measures incorporated into a highway-stream crossing system to monitor, control, inhibit, change, delay, or minimize stream instability and bridge scour problems. A plan of action, which can include timely installation of stream instability and scour countermeasures, must be developed for each scour critical bridge. Monitoring structures during and/or after flood events as a part of a plan of action, can also be considered an appropriate countermeasure.
