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). A buoyant flood protection barrier includes at least two such flotation structures and a plurality of flexible rods (25) extending between the end of one flotation structure and the end of an adjacent flotation structure for supporting the membrane (3) between the two flotation structures.
