Fuvahmulah is a natural wonder. Its secrets and thrills are unending. One of the most thrilling phenomenon is the strange wave movements in the reef of the island’s southern end.
Wave movements are a mystery here. You can witness all kinds of wave movements in just one location – spilling, collapsing and surging. The wave movements also occur in all directions. It is a spectacle to see waves moving away from the shore and waves travelling parallel to the island. Normally wave movements do not vary in shoe of the islands. But this variation is a mystery.
Waves are actually energy passing through the water, causing it to move in a circular motion, much like a buoy or seabird floating on the surface. The winds cause waves on the surface of the ocean. The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. Factors that affect wave movements are wind, depth, fetch and duration according to fluid dynamics.
As the different types of ocean waves reach the shallow waters near the shore, they begin to interact with the ocean floor, causing the waves to slow down and increase in height. As the waves continue towards shore, they become less stable and eventually break.
There must be some reasons behind the variation in wave movements occurring here?
According to scientists there are four basic types of breaking waves: spilling, plunging, collapsing, and surging. Spilling waves are gentle waves with crests that break softly towards the shore. These waves break when the ocean floor has a gradual slope. Plunging waves break when the ocean floor is steep or has sudden depth changes.
Therefore, it is obvious that the reef’s depth, matrix and other characteristics may vary immensely resulting in this natural phenomenon to occur. The tremendous ocean current beneath and above the surface could also be a factor for this mysterious wave movements. Perhaps there could be other hidden factors and forces behind this phenomenon. It would be a great idea to explore the hidden secrets of this reef for intellectual and ecological purposes. But it is an impossible dream as the whole country is plagued in poisonous politics.
