Geotexile tubes have become widely used in coastal and riverine environments to minimize erosion and scour, provide enclosure, containment or buttress slopes and bulkheads. One of the most promising appications is the use of dredged materials in a continuous or semi continuous operation, where the excavated slurry fills the geotextile tube, drains and is immediately deposited in its final location on site or nearby. This project described herein focuses on use of geotextile tubes in connection with dredging operations along the Delaware River, where a wide variety of soil types are encountered. The key operational parameters are those of filters in general, turbidity of the drained water, and rate of drainage. The problem addressed is developing a rapid performance-based test to support selection of the appropriate geotextile material for the soil being retained. This project has developed a hanging-bag test that simultaneously indicates dewatering rate and particle retention of a candidate geotextile in a scaled prototype of the actual final product, the filled geotextile tube. The testing program included developing the test set-up, determining an appropriate mix design for the MH soil used, and performing full scale pilot testing. Two tapes of geotextile were tested. The soil mix design was based on a weight relationship of 10:1 between water and Delaware River soil. Full-scale pilot tests quantified flow rates and particle retention.
