DESCRIPTION:
This course provides comprehensive training in the prevention of hydraulic-related failures of highway bridges. The effects of stream instability, scour, erosion, and stream aggradation and degradation are covered. Material for the 3-day course comes primarily from two Hydraulic Engineering Circulars (HEC), "Evaluating Scour at Bridges" (HEC-18), and "Stream Stability at Highway Structures" (HEC-20). The course provides training in conducting a stream stability classification and qualitative analysis of stream response. Quantitative techniques are provided for estimating long-term degradation, and calculating the magnitude of general and local scour at bridge piers and abutments for simple and complex substructures. A comprehensive workshop integrates qualitative analysis and analytical techniques to determine the need for a plan of action for correcting stream instability and scour problems. FHWA-NHI-135048 Countermeasure Design for Bridge Scour and Stream Instability is a recommended subsequent course that provides training in the selection and design of countermeasures for stream instability and scour problems, including development of a plan of action and an introduction to fixed and portable instrumentation for scour monitoring. See the listing for FHWA-NHI-135047 Stream Stability and Scour at Highway Bridges for Bridge Inspectors for a description of the 1-day course for bridge inspectors. OUTCOMES:
Upon completion of the course, participants will be able to:- Identify stream instability and scour problems at bridges
- Define problems caused by stream instability and scour
- Estimate the magnitude of scour at bridge piers and abutments and in the bridge reach
TARGET AUDIENCE:
Federal, State, and local highway hydraulic, structural, and geotechnical engineers and bridge inspectors responsible for maintaining the integrity of highway bridges against possible hydraulic related problems. Consultants who do bridge engineering work are encouraged to attend. |
