A portable, water-filled barrier system includes a plurality of water-fillable modules, each module being internally divided into cells that emulate a section of a sandbag dike or wall. Automatic valves can seal openings between the filled cells, so that a punctured cell will not cause cells below and behind to deflate. A manifold can be used to simultaneously fill a plurality of modules. The barrier system further includes at least one anchoring support base having an underlying portion that extends under at least one of the modules. A vertical portion of the support base extends upward behind and abuts at least one of the modules, and an anchoring portion includes openings that enable attachment of the anchoring support base to the underlying ground by stakes and/or spikes. A flexible sheet can be installed beneath and in front of the assembled barrier to further inhibit horizontal displacement of the modules.

A bottom boom and method of use is disclosed for containing heavy or sinking oils which migrate on an underwater floor. The bottom boom is comprised of an upper wall, a lower wall that abuts an underwater floor, a support structure and a ballast section. The upper wall and lower wall when properly supported by support structure provides an upright barrier to guide or stop heavy non-floating oils on an underwater floor. The support structure is a series of chambers, longitudinally spaced between the upper and lower walls of the bottom boom, such that when each chamber is filled with water the chambers vertically support the upper wall at an angle above the lower wall and horizontally maintain the lower walls width thus forming said upright barrier. Additionally the chambers can be filled with air to expedite recovery of bottom boom from underwater floor.

Embodiments of an inflatable dam sized to be secured to a foundation structure with an anchor line. The inflatable dam includes a main bladder and an overlapping layer. The main bladder is moveable between deflated and inflated states such that, in the inflated state, the main bladder extends with a tubular configuration. The overlapping layer is sized and configured to extend over a portion of the main bladder and, in the inflated state, concentrically aligned with the portion of the main bladder. The overlapping layer is sized to extend with an overlapping length and to extend laterally between a first end portion and a second end portion along the overlapping length, the first end portion being coupled to the fin structure and the second end portion being configured to be coupled to the anchor line and the foundation structure.

The present invention provides a self-positioning system of a deepwater underwater robot of an irregular dam surface of a reservoir, including cross reflection metal plates arranged on the irregular dam surface, and an underwater robot provided with a control motherboard, a water level indicator and a sonar system, wherein the water level indicator and the sonar system are respectively connected with the control motherboard, and the control motherboard is connected with a computer via a cable. The cross reflection metal plate has known coordinates and has four quadrants. A sonar signal emitted by the sonar system is reflected by the cross reflection metal plate to generate sonar reflection signals of four quadrants, and the sonar signals in the effective quadrants correspond to known coordinate parameters of the cross reflection metal plate so as to obtain the horizontal distance between the underwater robot and the irregular dam surface. The water level indicator is used for calculating the vertical position of the underwater robot. The computer calculates accurate positioning of the underwater robot according to the horizontal position and the vertical position. The present invention has the beneficial effects of being able to accurately obtain the positioning coordinates of the underwater robot in the deepwater of the irregular dam surface of the reservoir.

The present disclosure relates to a method of using a feedback loop from sensors to manipulate sea waves by applying concepts from optics interference and lensing. The method includes capturing, by one or more sensors, environmental data of an aquatic environment, wherein the environmental data relates to one or more of a wind speed, a wind direction, a wave pattern, a wave spectra, and a wave direction. The method includes analyzing, by one or more processors of a controller, the environmental data to identify a sensed environmental condition. Further, the method includes determining an optimal configuration of a wave interference device in the sensed environmental condition, wherein the controller is communicatively coupled to the wave interference device; and configuring the wave interference device to occupy the optimal configuration.

A compressible liquid retaining berm having a plurality of linear wall members and right angle corner members composed of a compressible, resilient material such that the wall members and corner members will rebound to a neutral state after being compressed. A longitudinal slot is disposed in the top wall of the wall members and the corner members, with the corner member longitudinal slots communicating with a recess positioned in the corner member. A liquid impermeable liner member is disposed on the interior side of the wall members and corner members, the liner member extending across the wall members and corner members. The liner member is secured to the wall members and corner members by positioning elongated anchor members atop the liner member in alignment with the longitudinal slots, such that the weight of the anchor members results in the anchor members being received within the longitudinal slots.

A device prevents flooding under sliding patio doors by blocking the space between a bottom of a sliding door panel and the top of the sliding door track. The device includes a reshapeable base that fills an external portion of a track of the sliding door to prevent water from pooling in the track and then from being driven by wind under the door panel. The shapeable base is made of a heavy material such as a sandbag that prevents the shapeable base from being blown out of the track, even during hurricane force winds. The device further includes a declined portion that directs rainwater away from the outer surface of the door panel, beyond the outer rim of the track. The declined portion thereby prevents rainwater from collecting within the track by directing the rainwater outward, beyond the outer rim of the track. An assembly of a plurality of devices can be utilized to protect a sliding door that has multiple panels, In the case of the assembly, a respective device is provided for each of the door panels in the sliding door.
