Abstract
A hydrostatic fluid containment system, or flood barrier, that is positioned underground in its open state consisting of a buoyant wall which floats up and above ground level when submerged in a fluid, creating a seal from both buoyant vertical and hydrostatic horizontal forces on the containment wall imposed by the contained fluid. The system will not open prematurely and restrict access of vehicles or pedestrians until containment is necessary. The system comprises a pivot seal which seals the barrier on the upstream side, as well as another sealing element that is positioned between the pivot seal and the buoyant wall. The pivot helps to tilt the barrier towards the upstream direction.
