Wave Reflection from Typical Sloping Dike in the North of Vietnam

The sloping revetment and the crest configurations appear to have important effect on wave reflection, especially the presence of crown walls may cause higher reflected wave and might modify the cross-shore current, and eventually affect the sea dike toe scour during storms. In this paper, the degree of wave reflection as well as the distribution of reflected wave are investigated through a series of fix-bed flume model experiments. Based on previous studies, a new spatial autocorrelation function that described the distribution of reflection coefficient in the vicinity of sea-dike structure, has been developed for sloping dike in the north of Vietnam.
