Abstract

The landware slopes of sea dikes in the north of Vietnam are steep and solely constructed by soil covered with grass due to the budget constraints and also the out-of-date design guidelines.The resistance against erosion due to wave overtopping of several grass covered slopes were tested with the Wave Overtopping Simulator to show if a slope covered with grass could withstand a certain amount of overtopping. An analysis of all test results obtained in the Netherlands and Viet Nam is made as an attempt to establish a reference for empirically assessing the strength of grass covers. Slope classification should be based on its specifications whether it is a plain slope or a slope with existing damages and obstacles.
