Tsunami induced sediment cloud: An experimental study

Abstract

Researches about tsunamis showed that a huge mass of water movement caused not only life and property losses on coastal areas, but also caused severe damages on ocean ecosystem due to huge mass of sand movements and tsunami backwash flow. In this study, it is aimed to understand the horizontal changes in suspended sediment concentration in water, originated from the tsunami run up and backwash flow with an experimental setup. This study has showed that the tsunami induced sediment transport has two layer sediment clouds as it is observed and the empirical equations have verified this fact.
