There has been much discussion about why there are so many rocks on Arthur/Patricia this year.  As well as King Edward and Alexandra.

Where have they all come from everyone is wondering?

Well, after a discussion with Peter Zuzek with Baird we got an interesting answer.

The state of the beaches is likely  the result of both a low activity weather year as well as the revetment on Arthur and sandbags on King Edward and Alexandra.

It was offered that the rocks are actually not “coming” from anywhere but rather, they are being “revealed”.

They have always been there.

But now that the existing revetment and sandbags are there — and the sand replenishment has thus decreased — these rocks are slowly being revealed.

They used to be covered by sand.

The stones we are seeing are not typically moved by waves nor are they stray pieces from the revetment,

It is the scouring we are now seeing.

As Peter stated:  “While the events like the storm in 2010 are terrible for the land owners, they are events that are the sand makers,  They put the sand on the beach.”

He did point out there is a fair amount of vegetation now growing again, to help stabilize the banks and it shows there has not been any recent big event to draw sand from the bank to the shores again.  That is part of the reason there may be less sand as well.

“There is a “pulse” to the beaches…some years lots of sand, some not as much.  Dependant on the waves and weather activity.”

But he also pointed out one can’t deny that this is also likely the result of less sand being accessed and less material being accessed from the banks — because of the man made erosion efforts.

It gets clearer and clearer what we should not be doing at VB and that other means such as sand replenishment and groins should become the new focus.
