Tim Kana of Coastal Science & Engineering wrote: "The measurements in November 2011 suggest that if any sand has shifted to south Bodie Island since nourishment, an equal volume has shifted to Nags Head from Kill Devil Hills". Kana said, "the Nags Head nourishment project is performing better than expected, and the profile is adjusting to a shape and configuration which is indistinguishable from a natural beach."
Interestingly, Kana also said that "following normal adjustment and fall storms, 52 percent of the nourishment sand remains on the visible beach above mean low water and 48 percent is contained (in the ocean) between mean low water and the 12-foot (ft) depth contour (~800 ft offshore).
A copy of Kana's letter and report can be found here
It has been EOD's understanding all along, and certainly before nourishment took place, that the problem with Nags Head's beaches was that there was not enough sand on the beach. EOD doesn't recall anyone saying there was not enough sand in the ocean off the beach and EOD will wager no one thought that was a big problem. In fact, everyone was saying, "the sand's eroding off the beach and out into the ocean". So,the problem as EOD understood it was that everyone wanted more sand on the beach, not out in the ocean.
Furthermore, EOD assumed everyone thought we were getting 4.3 million cubic yards of new sand on the beach and it would stay there for 10 years. That's what the engineer said, isn't it?
So now, Kana is telling us that " after nourishment and after adjustment only 52% of the nourishment sand is now on the visible beach above mean low water and 48% is now (out in the ocean) in the water below mean low water and 12ft of water! IN OTHER WORDS, IN TWO MONTHS, WE HAVE LOST 48% OF $32+MILLION DOLLARS WORTH OF SAND TO THE OCEAN....AND THE PROJECT IS A SUCCESS??
Well, if EOD was a Nags Head taxpayer with a 16 cents tax increase, he wouldn't care if there were 2 million cubic yards more sand out in the ocean now than there was a year ago, because he doesn't think a 12 foot wave slamming the beach cares how much sand is down under it. If you were a wave, would you?
EOD thinks the people wanted more sand on the beach to protect their investments, not more sand in the ocean for the waves to ride over and wash upon the beach like they did before. Gee Whiz !
By the way, EOD was on the beach yesterday behind the Comfort Inn and the ocean there is chomping at the bit to roll over the so called "visible beach" and wash against their illegal sandbags just like it did last winter. There was a nice beach cut forming there...and if it doesn't fill in before a two day northeaster hits...it will definitely play heck there just like it always has....But, January and February will tell the tale.
