Bald Head Island, North Carolina
Product: Geotube® Marine Structures Technology
Location: Bald Head Island, North Carolina
Bald Head Island has experienced serious beach erosion troubles since the mid-1970s. The island was losing the shoreline battle. A plan was needed to reclaim and protect the beach shoreline.
Geotube® marine containment technology was used for this shoreline project on the southernmost of North Carolina's cape islands. A series of 16 Geotube® containers (30' circumference x 300' long) were installed perpendicular to the coast [photos 1 and 5]. The units were hydraulically pumped with dredge material [photo 2]. One third of the Geotube® containers were buried back to the island's dune line [photo 3].
The width of the beach area increased after the Geotube® jetties were completed [photo 6]. Geotube® technology proved to be a cost-effective method of rebuilding the beach.
And in September 1996, only two days after the Geotube® installation, Hurricane Fran made landfall near Bald Head Island. No erosion occurred as a result of that Category 3 hurricane.
