Interaction between internal waves and surface waves over a slope-shelf

Abstract

In order to study the interaction between the internal waves (IWs) and the surface waves (SWs) with different periods over a slope-shelf, laboratory experiments and numerical simulations by using plunger wave maker are conducted in the paper. Laboratory results reveal that the wave period of IWs shows significant decrease during this process at long incident; at short incident, the wave period of IWs and SWs keep the same value. The results of the numerical simulation show that the short interaction time causes the weak internal hydraulic jump on front slope when IWs propagates over a slope-shelf. ? 2019 by the International Society of Offshore and Polar Engineers (ISOPE).
