Abstract
The crown height of revetment is determined as the sum of freeboard and necessary height from the viewpoint of allowable wave overtopping quantity. However, there is no rational method for the determination of freeboard thus far and therefore the freeboard has been determined empirically. This paper presents the method of setting the crown height of revetment considering the estimation accuracy of wave overtopping quantity. Schematic chart for evaluating the crown height in accordance with the probability of exceedence of wave overtopping quantity is presented.
