RUN-UP OF VERY LONG WAVES GENERATED BY BOTTOM-TILTING WAVE MAKER

【课程内容】

Motivated by the need to generate more realistic model tsunamis, a new wave maker has been developed at the University of Dundee. The wave tank is formed with an adjustable slope and a bottom flap hinged at the beginning of the slope. The new tank can generate both leading-elevation waves (LEW) and leading-depression waves (LDW), which are an order-of-magnitude longer than solitary waves for the same wave height-to-water depth ratio. In the present study, we report the maximum run-up heights of both LEWs and LDWs along a plane beach. While LEWs exhibit simple relationship between the maximum run-up height and the wave generation parameters, no such relation is found for LDWs. It was found that the maximum run-up heights for both types of waves can be described as a power function of the steepness of the accelerating phase of the wave at the point of wave generation.
