Abstract: A portable barrier including an elongate hollow container providing a chamber for holding fluent material to increase its weight has a stabilizing toe projecting outwardly from one of its sidewalls with the upper surface of the toe disposed at an angle relative to the horizontal and angling downwardly on progressing away from sidewall. Hinged connectors are provide at opposite ends of the barrier for connecting to adjacent barriers, and angled endwalls accommodate angular orientation of adjacent connected barriers relative to each other. A plurality of bores permit fluid to flow pass the barrier as desired, or to be stopped by the insertion of plugs. A removable flexible cover is placed over the hinged interconnection between adjacent barriers. The cover may be of a water-proof or filtering medium as desired.
