Evaluation of Bridge Scour Research

Since 1990, state highway agencies, federal agencies, and others have expended significant resources for research on bridge scour, particularly in the following areas: (a) prediction of scour at bridge piers and abutments, (b) selection and design of bridge-scour countermeasures, (c) stream bank protection, (d) tidal scour, and (e) analysis of river systems and methodologies for predicting channel instability. In 1997, NCHRP Project 24-08, "Scour at Bridge Foundations: Research Needs," prepared a comprehensive plan to identify and guide bridge-scour-related research. Development of this plan required the research agency to assess the validity and applicability of research related to bridge scour and fluvial system instability; define the state of practice; identify gaps, deficiencies, and potential improvements in current scour technology; and make recommendations for future research. Using the results of Project 24-08, the American Association of State Highway and Transportation Officials (AASHTO) has, through NCHRP, initiated and completed a number of bridge-scour-related research studies. In addition, FHWA and other agencies and institutions have conducted bridge-scour-related research studies related to the comprehensive strategy. The AASHTO Technical Committee on Hydrology and Hydraulics is currently developing two new manuals: "Policy for Design of Highway Drainage Facilities" and "Recommended Procedures for Design of Highway Drainage Facilities." To assist in development of the bridge-scour sections of these manuals, AASHTO needs a critical evaluation of bridge-scour research completed since 1990 with recommendations for the adoption of specific research results. These recommendations will be used by AASHTO in developing policies and procedures in the bridge-scour area for the two new highway hydraulic engineering guidance documents. NCHRP Project 24-27 was funded to critically evaluate bridge-scour research results completed since 1990 and make recommendations for adoption of specific research results by AASHTO and use by the engineering community in general. Project 24-27 is divided into three functional areas: (1) Pier Scour Processes and Predictions; (2) Abutment and Contraction Scour Processes and Predictions; and (3) Geomorphic Processes and Predictions. Separate but coordinated research teams will address each of these functional areas under the umbrella of NCHRP Project 24-27. Projects 24-27(01) and 24-27(02) are underway. This project will address the functional area 'Geomorphic Processes and Predictions' and will be conducted as NCHRP Project 24-27(03).
