Claim Text:
1. A self-actuating floodwater barrier unit for installation along a shoreline adjacent a place for a body of water, between a pair of walls transverse to the shoreline, comprising: a. a panel assembly comprising a flexible resilient panel and a plurality of rigid attachment members connected to said panel, said flexible resilient panel comprising one or more watertight chambers of size and arrangement to give said panel assembly water buoyancy; b. pivotation members comprising a stationary member for anchorage adjacent the shoreline and a moveable member connected to a said rigid attachment member on a lower portion of said panel assembly, the moveable member being moveably joined to said stationary member and pivotally rotatable upward from a normally horizontal disposition of the flexible resilient panel about an axis longitudinal with said shoreline under the influence of water buoyancy and hydrostatic pressure from a rise of said body of water; and c. a flexible tension member connected at one end to an anchorage lower than said panel assembly when the panel assembly is horizontally disposed and at the other end connected to a said rigid attachment member at a position on said panel assembly effective to limit upward rotation of the panel assembly to a predetermined extent.
