Countermeasures to protect bridge piers from scour
This report documents research on local scour at bridge piers resulting in the development and recommendation of a practical selection criteria for bridge-pier scour countermeasures, guidelines and specifications for design and construction of those countermeasures, and guidelines for their inspection, maintenance, and performance evaluation. Because of their critical role in ensuring bridge integrity and potentially high cost of these countermeasures, it is important that the most appropriate countermeasures be selected, designed, and constructed. The contents of this report are, therefore, of immediate interest to highway professionals responsible for planning, administrating, evaluating, designing, constructing, inspecting and maintaining bridges and other structures founded in erosive areas. The report is also of interest to those charged with specifying materials testing procedures and acceptable results, setting budget goals, and making policy.
