A flood barrier wall consisting of a flexible tubular flood chamber, skirts and an air-filled flotation collar. In its unexpanded and deflated mode the device is relegated to a substantially flattened condition which can be folded, rolled up or placed on a spindle for ease of transport and rapid deployment at a flood site. Deployment consists of placing the barrier on the anticipated flood site, weighting and fastening the skirts to the ground and inflating the collar. As rising flood water enters the flood chamber it expands said chamber, resulting in an effective flood barrier.

[ I claim:] [1.] A transportable flood barrier for use as a dam, dike seawall or the like comprising: a generally rectangular ground sheet made of a flexible, durable, water-tight material and capable of forming a seal against water intrusion when fastened to the ground and properly weighted; and, attached to its upper side, an expandable and collapsible tubular flood chamber extending the approximate length of the ground sheet, said flood chamber made of a flexible, durable water-tight material and fitted on one side with a plurality of ports permitting the flow of flood water in or out, said ports being adequately screened to prevent the entry of debris into the chamber; and attached to the upper portion of the flood chamber, above the ports, a flexible, durable inflatable tubular air chamber extending the approximate length of the flood chamber, which when inflated with air maintains a partial position above the water line, rising and falling as flood water dictates and raising and lowering the flood chamber in consequence; and the entire flood barrier being made of flexible and durable material so that it may be rolled up or folded up for ease of transport and deployment.
