Abstract
A temporary flood control barrier system comprising elongated flexible, inflatable, tubular ballast members secured to each other and adapted to be disposed on the earth's surface for anchoring a generally sheetlike vertically extendable barrier wall or an inflatable tubular barrier member disposed above and connected to the ballast members. The ballast members are at least partially fillable with a dense ballast liquid, such as water, and may be inflated with pressure air to add rigidity and increase the height of the flood control barrier system. The sheetlike barrier wall is held erect by spaced apart support poles and sets of flexible retaining lines also attachable to the barrier wall at spaced apart points. An elongated skirt or liner is attached to one side of one of the ballast members and is deployable on the floodwater side of the barrier system to minimize saturation and erosion of the earth's surface adjacent to the ballast members. The liner may be secured by elongated plate retainers and spiral auger type anchors. Substantially rigid connectors are adapted to connect the barrier sections end to end.
