Well... here is just a continuation of my findings (heh heh! Sounds like some kind of academician, eh?)
Interestingly, I wouldn't be surprised if the physical landscape of the East Coast beach undergoes many more changes. It is clear that the reclaimed land area is subjected to strong waves. The warning signs of danger to stay away from the unstable coastline is quite prevalent as you walk along the beach.
Hmmm... looks like the beach area might be reduced drastically sooner or later as a result of such natural processes...
