Depression internal solitary wave interaction with submerged obstacle.

The process of depression internal solitary wave interaction with submerged plate has been successfully stimulated in the present study. The characteristics of internal solitary wave interact with submerged plate have been reported. The results showed that both transformation and reflection were found in the wave-plate interaction. For reflected wave, the wave amplitude and wave energy obeyed logarithmic law with no dimensional blocking parameter. For transmitted wave, wave amplitude and wave energy followed exponential rule with the blocking parameter. The reflected and transmitted waves showed the same wave amplitude and wave energy, while the blocking parameter was nearly 0.8.
