【 摘 要 】

Wave run-up, wave set-up and wave run-down are determined by using the residence time in the form of a duration curve. This method introduced by FUHRBOTER and WITTE (1991) considers the totality of a run-up series without considering individual run-up events separately. By using the residence time concept, wave run-up is not any more a timeless event but can be described as a time dependent variable. The results obtained by using this concept are in good agreement with previous studies based on other methods for defining wave run-up, wave set-up and wave run-down. The residence time concept has been used for regular and random waves. This concept is particularly useful for random waves, because there is no need to count the number of waves loading a dike.
