Abstract: A flotation structure for a buoyant flood protection barrier includes a flotation body (1) adapted to rise and fall with flood water. A flexible membrane (3) is sealed at an upper region to the flotation body and sealed at a lower region. A plurality of panels (5) are hinged by means of hinge pins about substantially parallel horizontal axes, a topmost panel being hinged to the flotation body, a lowermost panel being hinged substantially at ground level, and intervening panels being hinged to each other. A scissor arrangement (9) is pivotably mounted at an upper end to the flotation body and pivotably mounted at a lower end and provided with a pivot pin (17) at a crossing point of arms (11, 13) of the scissor arrangement, the pivot pin being secured to a member (19) provided on at least one of the hinge pins (23).
