Abstract

The Simulator was applied to test the resistance against wave overtopping of grass covered dike slopes in Viet Nam. Observation and measurement during destructive tests were performed to investigate the development process of damage induced by overtopping flow. Damages were likely to be initiated at transition of either geometry or materials, at eroded holes and around objects existing on the slope. Grass cover could withstand a certain overtopping rate that varies widely and in order of 10 l/s per m.
