Three-dimensional woven geotextiles for containment dike construction
Every year, approximately 300 million m3 of sediment is dredged from the United States waterways. Although the primary purpose is to increase navigational capacities of channels, engineers are constantly seeking more effective and environmentally acceptable disposal methods for dredged materials. When the Port of Houston Authority faced this challenge, the Beneficial Uses Group (BUG) decided to utilize dredged material from the Houston Chip Channel to construct over 1720 ha of intertidial salt marshes. Starting in February 1994, three geosynthetic materials were installed along 1000 m of dredged material containment levee at a demonstration marsh. Proposed as cost-effective alternatives to conventional riprap, the three materials chosen included a cellular confinement system, fabricated geotextile tubes, and a three-dimensional woven geotextile for the shoreline protection. The three-dimensional woven geotextile was installed on 2H:1V slopes and secured using anchor trenches, hairpin-shaped reinforcing steel bar and duckbill anchors. To date, the product has helped to maintain a stable, nonerosive levee and promoted diversified aquatic vegetation. The project continues to be closely monitored by a number of official authorities. The paper describes the background, selection, installation, and performance of the three-dimensional woven geotextile used for erosion protection along 122 m of levee of this demonstration project. Chronological data, field observations and photographs are included to compliment the observations and conclusions made from the time of installation to present.
