A STUDY ON SPLASH GENERATED BY BREAKING WAVE ACTING ON A VERTICAL WALL

Abstract

 In order to take countermeasures against salt damage of pier superstructure economically and efficiently, it is indispensable to clarify the wave conditions of splash generation at the vertical wall, and to grasp the characteristics of the splash. Using a series of images capturing splash generation process by a high speed camera, characteristices of splash such as the number of droplet, diameter and splashing velocity of each splashing speed, and so on are measured by the PIV and PTV technique and the relationship between splash and wave characteristics was investigated.
