Abstract: In 1991, the Federal Highway Administration (FHWA) issued the Technical Advisory 5140.23 that required all bridge owners to evaluate existing bridges for potential failure due to scour. Scour is the engineering term used to describe the natural process that results in the removal of sediment from around a bridge’s structure, such as abutment walls and piers, and from the bottom and sides of the stream bed due to the flow of water. This project is an assessment of a U.S. Army bridge that crosses a waterway to determine the degree of scour vulnerability and scour depth. The purpose of this study is to develop analytical calculations using acquired data to determine scour depth based on a rapid scour assessment of an existing bridge at Milan Army Ammunition Plant at Milan, TN. The scour assessment was conducted by using the Rapid Estimation Method for Limited Site Data developed by the U.S. Geological Survey. This method allows an estimate of the scour depth to be made in a time-effective manner by using data that can be easily collected or estimated during a brief bridge site visit. This report provides an explanation of the method used to obtain scour-depth estimates and an analytical assessment for vulnerabilities and risk of failure due to scour caused by floods in the magnitude of a 100-year event with limited available data.
