A PREDICTION MODEL OF IRREGULAR WAVE RUN-UP HEIGHT ON COASTAL STRUCTURES

Cheong-Ro Ryu, Hong-Yoon Kang

Abstract


The characteristics of irregular wave run-up on coastal structures are discussed related with spectrum shape and grouping parameters of incident waves using the results of 200 cases of hydraulic model experiments. It is clarified that wave run-up is affected by the effects of the irregularity of incident waves and the slope configurations of structures. A statistical model to estimate the run-up height from the incident wave properties is proposed considering 90 % confidence intervals. Also, the simple probability distribution model of irregular wave run-up height is developed and proved to be useful to the design of coastal structures.
