Development of a New Tsunami Generator for Multiple Sources

Abstract

The medium-sized experimental wave gengineer7snerator implemented at the Ujikawa Open Laboratory of Kyoto University’s Disaster Prevention Research Institute consists of a piston wave maker, a head storage tank and a current generator for reproducing long waves such as tsunamis and storm surges. The experimental series we discuss predicts the generator’s applicability in testing models. These three operating systems are controlled by a single operating system, and start time iscontrolled separately based on target tsunami and storm surge profiles. A sharp tsunami profile is reproduced when the start timing of the piston wave maker and tank gate opening is adjusted. The generator reproduces different types of tsunami wave, making it a strong tool in the research engineer’s arsenal for predicting the effectiveness of hardware “resiliency.”
