A Review of Methods for Protecting Highway Embankments from Overtopping Flow

Highway overtopping due to floods is one of the critical causes of road damage in Central Vietnam because of the potential for rapid soil erosion and mass wasting resulting in partial or complete failure of the roadway embankment. This paper focuses on feature analysis of the hydraulic characteristics of water flowing over an embankment providing a basis for understanding the erosion process. The effectiveness and application conditions of several modern methods to protect road embankments from overtopping flow are also presented.
