Videos on constructive and destructive interference in wave dynamics and how waves breakup in shallow areas

Briefly, the result of constructive interference is a higher wave front while that of destructive interference is a trough. The concept can be visualized in the above video taken at Labrador Park, Singapore.

In addition to the concept of constructive and destructive interference, the video also features another facet of water waves: its interaction with land. Specifically, it can be clearly observed that as a complete wave front approaches shallow areas, specific segments interacting with the area would breakup into foamy water. This is the underlying mechanism leading to the formation of large waves common in tsunami, where a water column is forced upwards by shallow land.
