Dauphin Island

conference_logo_mashupIt’s been a busy couple of months around here. Our research group hit the conference trail in late October and didn’t stop until a couple of weeks ago. The tour started in late October with a trip to Tampa, Florida for the 2012 Restore America’s Estuaries conference. The RAE 2012 proceedings can be found here. We gave two poster presentations on our Mississippi-Alabama Sea Grant Consortium (MASGC) living shorelines research project: one on our living shorelines database effort with ASCE-COPRI [2], and another on the development of our decision support toolkit for the optimization of breakwaters [5].

 

Less than 24 hours later, my wheels touched down in Miami, Florida for the ATC-SEI Advances in Hurricane Engineering conference. This event brought together engineers from many fields for a two-day meeting on issues ranging from flood damage to wind failure. Here, we presented the results from our deployment of storm surge and wave gages on Dauphin Island, Alabama, during Hurricane Isaac [7]. The deployment is part of a long-term monitoring program funded by MASGC.

 

The late fall months of even-numbered years on the Gulf Coast brings with it not only empty, beautiful beaches but also the Bays & Bayous Symposium. This bi-state conference is a collaboration between the MASGC and Mobile Bay National Estuary Program, with each program taking turns hosting the event in their home state every four years. Our research group provided three presentations at this event: one poster presentation on laboratory experiments conducted to measure the wave attenuating capability of various living shoreline breakwater technologies [1]; an oral presentation on our MASGC-funded living shorelines project [4]; and another oral presentation on our MASGC-funded surge and wave monitoring program for Dauphin Island, Alabama [6].

 

Our (mostly) annual pilgrimage to the American Geophysical Union Fall Meeting in San Francisco, California concluded the fall conference tour in early December. I gave a poster presentation, and co-authored another, in the Nearshore Processes section of Ocean Sciences on some work that I did with my colleague and good friend Dr. Rob Weaver of the Florida Institute of Technology. You may recall a series of blog posts from the field in late July describing a three-day field experiment conducted in the Indian River Lagoon estuary of Florida using the South Alabama Jag Ski. Our complementary poster presentations [3,8] provided an overview of the experiment, as well as preliminary results. We hope that these posters rapidly evolved into manuscripts in the coming months, and we thank all of the constructive criticism we received during the meeting.

 

Normally I might try to link up all of our posters and presentations… but there are just too many to do that in one post. So, if you have a specific interest in something mentioned here, please just shoot me a message or leave a comment and I will send you the stuff. In order to make this process a bit easier please just refer to one of the specific citations listed below… these cover everything mentioned in this post. I will eventually link up everything in some revamped research pages coming in early 2013. Also of note… we will be moving to a new domain in the coming days. The new site address will be http://www.southce.org/bwebb. Hopefully you will receive an automatic redirect when accessing the site using the current domain name. More details to follow in a subsequent post.

These photos demonstrate the amount of sand erosion from the beach face of Dauphin Island during Hurricane Isaac.

Here’s a quick update for those of you following our research on storm surge and waves at Dauphin Island, Alabama. Four of the five gauges successfully recorded data. Fortunately, the one gauge that did not record was the one on the north side of the island, which likely did not see any water. Our gauge deployed on the beach definitely recorded waves, but I haven’t had a chance to perform any type of analysis yet. The photos at right show the same gauge location before and after the storm. Note the amount of erosion that occurred under this house. Check back often for more updates… or just subscribe to the RSS feed to get the updates automatically!

As part of an ongoing storm surge and wave monitoring project for Dauphin Island, Alabama, we recently deployed 5 surge/wave gauges and an atmospheric pressure gauge to record the effects of Hurricane Isaac as it passes south of our study area. The gauges were deployed early Monday morning (8/27/2012) with the help of USA CE graduate students Richard Allen and Chris Marr. A special thanks to LaDon Swann, Director of the Mississippi-Alabama Sea Grant Consortium, who is responsible for funding this ongoing project, for his help in the field installing the gauge shown at right. It’s not every day that your funding sponsor shows up in the field, before sunrise, to help you conduct your research!

 

Additional surge gauges are being deployed in the area by the USGS. When combined, all of the gauges should provide a very detailed record of water levels across the north-central gulf coast during Hurricane Isaac. If there is enough surge over Dauphin Island during the storm, we should also be able to generate a good record of wave characteristics across the island. Check back often for updates using the tag “Dauphin Island”… we should be retrieving the gauges later this week.
