Abstract

A unique water containment wall or barrier employs a flexible envelope that is extendable in a longitudinal direction from a collapsed condition for storage and transport into an expanded position for use. Support ribs disposed at spaced apart positions along the longitudinal direction provide support and shape retention to the envelope, the interior of which is fillable with water to weigh down the envelope down against oncoming or expanding waters. A unique fastening mechanism attaches a pair of wail or barrier sections together by using an inflatable member to force apart a pair of profiled ribs on the two sections into engagement with matching-profile walls of a channel member that bridges together the two sections over the ribs. A bumper mechanism rises and falls with water levels to protect the wail or barrier against impact by floating debris.
