<p>In a method for providing a portable flood barrier (1), flood barrier sections (2, 3, 4) comprising two parallel, spaced apart, inflatable, elongated tubes (5,6 or 5,7) which are joined by a waterproof web (8) are placed on the ground (9) with the side of one of the tubes (6 or 7) facing the flooded area (10), and the other tube (5) facing away from the flooded area (10). Both tubes (5,6 or 5,7) are inflated, and ballast water (13) is filled on the web (8), whereupon, when floodwater (14) rises, the tube (6 or 7) facing the flooded area (10) floats in the floodwater (14) and due to its buoyancy rises, thereby forming a flood barrier (1).</p> |
