A flood control barrier for separating water in a wet area from an area to be maintained substantially dry comprises a flexible exterior membrane made of liquid impervious material and including elongated upper and lower membrane sections joined at a closed longitudinal downstream end of the exterior membrane opposed to an open longitudinal upstream end thereof. The upper and lower membrane sections are connected by internal partition walls and are displaceable between expanded and collapsed positions, wherein in the expanded position, the upper membrane section is spaced from the lower membrane section at the open end of the exterior membrane such that water may flow through the open end and be received between the upper and lower membrane sections such as to be trapped therein, i.e. by the closed downstream end thereof which prevents the water from flowing past the barrier.
A barrier for retaining a liquid upstream thereof, comprising liquid impervious elongated upper and lower walls joined at a closed longitudinal end of said barrier opposed to an open longitudinal end thereof, said upper and lower walls being displaceable between expanded and collapsed positions, said lower wall being adapted to be positioned on a supporting surface, at least one deployment limiting member being provided to limit a deployment of said barrier to said expanded position, wherein in said expanded position, said upper wall is spaced from said lower wall at said open end of said barrier, whereby a liquid may flow into said barrier through said open end while being restricted from flowing downstream past said barrier by said closed end thereof.
A water barrier for separating a wet area from an area to be maintained substantially dry, comprising a liquid impervious flexible wall adapted to define in an expanded position thereof an upstanding curved profile, said curved profile defining a closed downstream end and an opposed open upstream end, said barrier being adapted to be positioned on a supporting surface, said flexible wall being adapted to receive water through said open end in said expanded position, whereby water is restricted from flowing downstream past said barrier by said closed end of said flexible wall.
A water barrier for separating a wet area from an area to be maintained substantially dry, comprising liquid impervious elongated upper and lower walls joined at a closed longitudinal end of said barrier opposed to an open longitudinal end thereof, said upper and lower walls being displaceable between expanded and collapsed positions, said lower wall being laid on a supporting surface, wherein from said collapsed position, said upper wall raises with a level of water up to said expanded position with said upper wall being spaced from said lower wall at said open end of said barrier, water in said barrier being restricted from flowing downstream past said barrier by said closed end thereof.
