Hydraulics Engineering PublicationsTitle: Evaluating Scour at Bridges, Fourth Edition Description: Evaluating Scour at Bridges, Hydraulic Engineering Circular No. 18 (HEC-18), presents the state of knowledge and practice for the design, evaluation and inspection of bridges for scour. Namely, the purpose of this document is to provide guidelines for the following: designing new and replacement bridges to resist scour, evaluating existing bridges for vulnerability to scour, inspecting bridges for scour, and improving the state-of-practice of estimating scour at bridges. There are two companion documents, Stream Stability at Highway Structures (HEC-20) and Bridge Scour and Stream Instability Countermeasures (HEC-23). These three documents contain updated material from previous editions and the publication Interim Procedures for Evaluating Scour at Bridges issued in September 1988 as part of the FHWA Technical Advisory T 5140.20, Scour at Bridges. T5140.20 has since been superseded by T5140.23, Evaluating Scour at Bridges dated October 28, 1991. This fourth edition of HEC-18 contains revisions obtained from further scour-related developments and the use of the 1995 edition by the highway community.
