ABSTRACT OF THE DISCLOSURE A hydraulic structure is provided in the form of a flexible, flat, corrugated plastic tube having a relatively oblongated cross-section, with apertures associated with the grooves of the corrugation. The tube is enclosed in a geotextile sheath. The two relatively flat sides or panels of the tube are separated from each other by a plurality of pairs of cuspations, which project inwardly from the panel surface. Cuspations from the opposing panels are secured to one another thereby providing increased structural integrity.
