Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form of a Technical Advisory, provides guidance to engineers in the design of new and the evaluation of existing bridges as well as scour countermeasure techniques. The program stresses the use of a multidisciplinary team of hydraulic, geotechnical and structural engineers to provide an organized approach to the evaluation of scour at bridges. In this paper, a summary of the scour evaluation program is presented.
