ABSTRACT:
A multiple bladder flood control system, for preventing flood waters from reaching a protected area from a flooding area, comprising a bladder assembly. A trough is dug between the protected area and the flooding area, having a trough bottom, a trough first side, and a trough second side which are all preferably surfaced with concrete. The trough first side faces the protected area, and the trough second side faces the flooding area. The bladder assembly is anchored to the trough bottom with an anchor plate. The bladder assembly comprises at least a lowermost bladder and at least one upper bladder. The bladders are attached with a common connecting surface which faces the flooding area. The bladder assembly is normally deflated, is stored fully within the trough, and the trough is covered with a cover plate. When flood waters are advancing, the cover plate is removed and the bladder assembly is inflated. The lowermost bladder remains in the trough and is pressed against the first wall by water entering at the second wall. The upper bladders extend above the trough to prevent the flood waters from reaching the protected area.
