Abstract
A flexible water-permeable geotextile tube having flat ends when filled with fill material. The tube has separate end panels that are attached to a tube body at the tube body's opposing ends. In one embodiment of this invention, the separate end panels are configured to have the same shape as that of a cross-section of the tube body when the tube body is filled and installed. The cross section of the tube body may be determined before installation by determining the relationship between the height, circumference, the fill material, and the surrounding environment into which the tube is planned to be installed.
