To provide a floating flap gate that requires an auxiliary force of a counterweight or the like, and in which bending does not occur in a forward end portion of a door body, even in cases in which an installation site has a wide span. A floating flap gate 1 having a forward end portion 2c of a door body 2 that is configured to rotate around a base end portion serving as a fulcrum at a time of a rising water, so as to float upwards, and provided with an upper beam 2d attached to the forward end portion 2c of the door body 2 and a door body suspension member 3 contained within the upper beam 2d, and having two ends each being connected to one end of a wire rope 4. A counterweight 5 is connected to the other end side of the wire rope 4 as a pulling device. Bolts 6b are used as adjusting members interposed between the upper beam 2d and the door suspension member 3, and are inserted into bolt holes 6a provided on an upper surface of the upper beam 2d, so as to exert an opposing force to the tension of the wire rope 4 resulting from the weight of the counterweight 5 acting on the door body suspension member 3, the opposing force being applied uniformly to the upper beam 2d during ordinary use.

A deck board assembly is disclosed for constructing a deck board with drainage and storm surge damage prevention features. The assembly includes a plurality of deck board panels, each comprising an extruded or pultruded panel body with an internal screw boss, an overhang, a ledge, drainage openings on the topside, and underside openings. The panels also have a chemically bonded use surface with corresponding drainage openings. A finishing feature is provided to engage with the overhang and straddle at least two deck board panels. This innovative design allows for easy assembly and provides enhanced protection against storm surges and water damage, making it an ideal solution for outdoor decking applications.

A buoy and mooring system provides a robust buoy protective of markings thereon, easily retrieved for inspection and service, weighted and levered for maintaining self-righting, vertical orientation and anchored with a non-corroding system of connectors and links running from surface to sea floor. A mid-line float resists entanglement, and can be installed or uninstalled by operation of various worm grip mechanisms. A slack line region accommodates changing tides. An upright tube, weighted at a lower end and flanged at an upper end thereof, secures a buoy in place but pulls up through the buoy for easy retrieval by boat crews. Embedding an anchor is by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.

The present invention relates to means for substantially reducing evaporation from an open body of water comprising a plurality of domes which cover the surface of the water. The domes are hollow with a predetermined buoyancy for maximum surface coverage and self-stabilization without added weight, and are preferably made of transparent or translucent polycarbonate, high-density polyethylene, or acrylonitrile styrene acrylate, and also having a minimum light intensity of 2700 lux through the dome to sustain organisms living in the open body of water.

An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.

Self filling flood-protection bag consists of two enclosed chambers (1), that are interconnected by terminal yoke (2) in form of letter T and that are made of polyester fabric with high water absorbing capacity. Chambers (1) are filled up with granular or jelly mixture of water superabsorbents (3) based on cross-linked polyacrylate (SAP). Terminal yoke (2) contains two handling metal eyelets (4).

The present invention provides a system and method for detecting underground tunnels by using bentonite-slurry.

A dock coupling assembly that connects multiple dock segments to one another, wherein the dock coupling assembly comprising a female attachment bracket having a base portion and an offset portion that is connected to the base portion and is out of alignment with the base portion. The female attachment bracket further comprises a vertical flange on an inner surface that travels from a top edge to a bottom edge, and wherein the dock coupling assembly also comprises a male attachment bracket comprising a first outwardly extending engagement member and a second outwardly extending engagement member located on the base plate outer surface along the proximal edge, and wherein the male attachment bracket further comprises a base plate vertical flange that travels from a base plate top edge to a base plate bottom edge.

A panel for a seawall has a frame. The frame has a first area and forms front surface which is substantially planar. A typographical member disposed on the frame has a second area, less than the first area. The typographical portion extends in a direction away from the frame and forms an uneven surface, the surface having at least one depression therein having a depth of at least three inches.
