Abstract

This paper deals with the propagation of erosion wave in Cua Dai Beach in Central Vietnam under the influence of longshore sediment movement using analytical results from the simplified equation of the one-line model. In addition, measured shoreline positions obtained from Landsat images are utilized to validate the calculated results. Effects of the waves on the shapes of the erosion/accretion zones along the Cua Dai Beach are observed. Using the analytical solutions, the propagation speed of the erosion wave is estimated as 37 m/y while this value is 54 m/y in reality. Coastal structures such as seawalls located along the Cua Dai Beach is causing more severe erosion along Cua Dai Beach.
