Abstract:This TechBrief provides the most recent research product in scour formation and offers an interim support for foundation design of bridges vulnerable to scour caused by tsunamis. This research supplements the product from the Transportation Pooled Fund study TPF5-(307), Validation of Tsunami Design Guidelines for Coastal Bridges, which developed an evaluation method for tsunami loading for bridge design (Lynett et al. 2021). The formulas developed in this study, which can be used to assess tsunami-related scour depths at bridge foundations, are derived from a small number of experimental and numerical tests with a limited scope. More research with a broader parametric variation is underway.
