The beach in front of tree house

[Rob]

As I posted originally back about 2 years ago, as an interesting side note, a global map showing the actual world sea level from 1993 to 2010 taken from satellite data was released earlier in 2012. This study is the first of its kind and shows that Jamaica has actually seen a sea level decrease for that 17 year time period. (Please note the light and darker blue colors surrounding the Negril - this denotes about a 1-3 mm decrease in the sea level)

I am sure all those numerous storms we had in mid 2000's (that one year they ran out of names!??!) led to more than its share of the "erosion" stories did that occurred back then at the Treehouse and any other properties being talked about. The whole beach was different at that time and has taken time to return.

But out of curiosity, should something really be called "erosion" if it can come back?

Can things "un-erode"? Or would that be like something "un-rusting" once that something has become rusted and ruined? (grin)

If it can "un-erode", did it actually "erode" in the first place? Or just get misplaced and put back?

More food for thought...

Well, erosion isn't quite the same as 'rusting' since erosion does not involve a chemical reaction. In a sense, yes, the beach can 'un-erode', although it's usually referred to as deposition or accretion. Happens all the time in a dynamic system like this.

That you for the response, in dynamic beach ecosystems, erosion is not a permanent thing. The sand gets repositioned and then can be restored by nature.

I feel that most people think of beach erosion as a one-way event. Not enough is mentioned about deposition or accretion. Erosion is not permanent.

And with that first of its kind study that shows the sea level DECREASE around Negril along with the fact that accretion can and does occur, it should not be a surprise to anyone that the beach at the Tree House and other areas is increasing.

But I think when people hear "erosion" they think more of the "rusting" concept than accretion bringing back what eroded...
