Luong, N.Q. Verhagen, H.J. Schiereck, G.J. Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2011-09-05 Abstract The resistance of various grassed slopes against wave overtopping has been appraised by means of the Wave Overtopping Simulator in situ for a couple of years in Viet Nam. Destructive test results show that a dike slope covered with grass could suffer a certain overtopping discharge not smaller than 20 l/s per m. During testing it was difficult to predict when a slope starts to be damaged, however, damages tend to follow a more or less similar process of development. The concept of “erosional indices” and the method of “cumulative overload” (van der Meer et al., 2010) are applied to the simulator tests in Viet Nam. Critical velocities were then estimated for different kind of grassed slopes.
