Abstract: Flood barrier assemblies in land near a water frontage shoreline have next adjacent panels actively erectable into a continuous barrier preventing flooding of the land. In one configuration one lateral side of a panel is a contact surface and the other lateral side carries a gasket. The panels are sequentially raised with a first to raise panel presenting a contact surface to the gasket of the next adjacent second to raise panel. In another configuration, a contact surface is on opposing lateral sides of two panels separated by a next adjacent panel between them having gaskets on both its lateral sides. The spaced first panels raise before the second panel. The raised panels may be in a linear or curved array or a combination of linear and curved arrays. Either configuration and order of raising erects a flood barrier wall sealed panel to panel by the gasket between adjacent panels.

Abstract: A system is provided for automatic operation and status indication of a marine barrier gate. Embodiments include a system having a buoyant barrier gate that is movable between a closed position and an open position. An actuator moves the gate between the open and closed positions, and a sensor is operably connected to the actuator to generate data relating to a position of the barrier gate between the open and closed positions. A processor receives the data from the sensor and processes the data to move the gate between the open and closed positions, and detect the position of the gate. A human-machine interface is operably connected to the processor for communicating the detected position of the barrier gate to a user.

Abstract: Flexible containment tubes form sections of a dike for fluid containment. For example, multiple vinyl-coated polyester tubes with a 19-inch diameter may be filled with water and stacked on top of each other to create a temporary diversion dike. Multiple sections of dike may be abutted together to form longer sections of dike. A vapor barrier or plastic membrane may wrap over dike sections and/or weaved through the flexible containment tubes as they are placed prior to filling. Configurations of the vapor barrier and associated anchoring mechanisms improve the utility of dike sections by reducing hydrostatic pressure of contained fluid on the dike, harnessing the weight of fluid columns, and mitigating seepage through the dike sections.

Abstract: A marine barrier system is provided with two elongate buoyant members, a net support member between and above the two buoyant members, an elongate load bearing member spaced from and between the buoyant members, and a lower ballast member between the two buoyant members and below the buoyant members. Stanchions extend between the members to support them and maintain the spacing between them. An impact net is attached to the net support member and the load bearing member. When a moving vessel impacts the impact net, the net deflects to transfer a force of the impact to the net support member, the stanchions, the load bearing member and the buoyant members, which engage the water to transfer the impact force to the water and arrest the motion of the vessel. The ballast member provides a force to restore the barrier to an upright position when the barrier rotates from vertical.
