CLASSIFICATION OF INTERNAL WAVE BREAKING OVER A SLOPE WITH THE CHANGE IN THE THICKNESS OF PYCNOCLINE

Abstract

 Internal solitary waves are likely to be excited when eternal forces are given, such as wind or tide. In the case where the thickness of pycnocline is very thin, the classification index is successfully proposed in the previous study. This study thus investigates whether the classification index can be applied or not even when the thickness of pycnocline becomes thicker by using a three-dimensional hydrodynamic model, Fantom. As a result, there are some differences due to the increase in the thickness of pycnocline. However, they don’t change their specific breaking forms, so it is concluded that the classification index can be applicable when the thickness of density interface changes.
