Dana Trierweiler, P.E., Executive Vice-President of Infrastructure Alternatives, Inc., presented his paper, “Slowing the Swelling Seas: An In-Depth Look at the Geotextiles Installed in the Grand Isle, LA Hurricane Rehabilitation Project,” at the 30th Annual Western Hemisphere Dredging Conference and Texas A&M 41st Annual Dredging Seminar. The conference was held at the RIO Mar Wyndham Resort and Spa in San Juan, Puerto Rico, June 6 – 9, 2010.
Dana’s paper is a case study of the Grand Isle Hurricanes Ike & Gustav Rehabilitation Project, which was performed in Grand Isle, Louisiana during 2009. Infrastructure Alternatives installed 30,100 lineal feet of geotextile tubes over the course of the project, which involved using geotextile tubes filled with dredged sand slurry to create an artificial dune structure. The geotextile tube dune is designed to limit erosion of the beach during a storm event by absorbing the forward momentum of the surf and holding the sand that makes up the dune in place, within the geotextile fabric skin of the tubes.Share this:
