Abstract

An investigation of the erosion of highway embankments caused by flood overtopping is presented. Data collected from a series of laboratory tests and field investigations were evaluated to develop a methodology for quantitatively determining embankment damage. A computer model, verified by using laboratory and field data, was developed to simulate the hydraulics of overtopping flow and to estimate the erosion rate of the embankment. The computer model was used to generate nomographs and to develop a step-by-step procedure for estimating damage to roadway embankments. The effectiveness of five embankment protection measures was evaluated during the laboratory tests. Critical velocities and failure criteria associated with each protective measure were qualitatively established.
