A geotextile container and system for constructing a water barrier or dam is disclosed. A system for maintaining fill material solids in position to form a barrier comprises an elongated sheet of geotextile material capable of coiling upon itself to form a helical structure. Further, a means for seaming the first elongated sheet into a tubular container and filling the container with solids is presented. Fill material solids may be held in position by a tubular shaped container that forms a barrier or dam. An inner liner also may be employed in the tubular container. Cradle tubes may be deployed on either side to hold the container in position, such as when the container is struck by high energy waves.

A caisson breakwater provided with vertical duct 2″, room 3″, air-duct 4″, self-rectifying turbine 5″. Under the fluctuations of wave pressure on the outer opening 6, the water, alternately, enters and exits, so that the air in room 3″, alternately, is compressed and expands, and an alternate air flow is produced in the air-duct 4″. The vertical duct 2″ and the room 3′, form a U-conduit, and the air in the room 3″ acts as a spring. The eigenperiod of oscillations in said U-conduit grows as the width of the vertical duct 2″ is reduced and / or the length of said vertical duct is increased, and / or the width and height of the room 3″ is increased. The eigenperiod is fixed close to the wave period of the waves which convey the largest amount of wave energy in a year, so as to absorb a very large quantity of wave energy.

A device is provided for preventing shoreline erosion and for rebuilding the sand beach along the shoreline of a large body of water. A series of the devices are placed in side-by-side relation essentially parallel to the shoreline. The device includes a hollow plastic structure fillable with a heavy material, such as cement. The structure has a trapezoidal configuration to lower the center of gravity of the device and includes inclining front and rear walls converging toward each other to the top wall. The hollow plastic structure includes a plurality of tubular members extending from the front wall to the rear wall. The front and rear walls have access apertures opening to the tubular members. The tubular members gradually taper from a predetermined diameter at the access apertures in the front wall to half of the predetermined diameter at the access apertures in the rear wall to reduce the velocity of the flow of water to the large body of water.

A modular flood wall assembly having a relatively flat base member having a plurality of ribs extending therefrom. The assembly further comprises a plurality of interconnectable blocks, with each block having a top surface with at least one hollow protuberance, at least one side wall, a hollow interior, and a bottom surface having at least one hollow cavity. The cavities on the bottom surface of the blocks are matable with the ribs on the base member. The protuberances on the top surface of the blocks are matable with the receptacles on the bottom surface of a corresponding block.

A levee and barrier module for fluid control and containment is provided including an outer module shell and a module-to-module connection system to attach adjacent outer shells. The outer module shell, being in the general shape of a prism or prism with curvilinear section, is formed by opposing side walls and two opposing end walls, and is configured to enclose or support filler material. The two opposing end walls are configured with end apertures. The outer module shell defines a top aperture and a bottom aperture. When modules are placed end to end in a levee structure the end apertures allow filler material communication horizontally between adjacent modules. The bottom aperture allows filler material communication with the earth below the module. The top aperture allows filler material to be added to the module, as well as visual observation of, and maintenance of, the amount of contained filler material.

A portable, inflatable flood wall is characterized by a sheet of synthetic plastic material which is folded back on itself to define a chamber between bottom, rear and front portions of the sheet and within which at least one inflatable bladder is secured. When the bladder is inflated, the rear portion of the sheet is erected to a vertical position which prevents water from passing beyond the sheet. The front portion preferably contains a plurality of openings to allow water to enter the chamber. The weight of the water on the bottom portion of the sheet serves to hold the wall in place. A plurality of such walls may be connected in end-to-end relation to construct a wall of a desired length.

The invention discloses an energy dissipation type debris flow check dam combined draining and guiding and blocking. The check dam comprises a dam body foundation and a dam body main body arranged above the dam body foundation, wherein the dam body main body comprises a plurality of buttresses distributed at intervals, a horizontal grille is arranged between each two buttresses, the buttresses extend towards upstream compared with the horizontal grilles, and the height H of the horizontal grilles above ground is in the range of from 0.5 to 1.0 m. The horizontal grilles are hollow, and drain holes are formed in the horizontal grilles and provided with transverse beams and longitudinal beams for supporting. Compared with the prior art, the buttresses are used for supporting the dam body and blocking coarse grain; drain holes are used for draining and guiding water of debris flow passing through the check dam, destroying constitutive property of the debris flow, and avoiding clogging of constitutive property; the horizontal grilles are used for conducting energy dissipation type debris draining and guiding, improving discharge capacity of the dam body, enabling the whole check dam not prone to clogging, improving capacity of resisting secondary debris flow after debris flow discharging once, and meanwhile safety of downstream can be endangered.

A portable, water-filled barrier emulates a sandbag dike or wall without requiring sand or intensive labor to install. The barrier is made of a light, flexible material that can include nanofiber. Some embodiments are formed from a plurality of interlocked water-filled cells, with a forward-facing water barrier sheet. Other embodiments are unitary shells that are internally divided into cells, with internal openings that permit water to flow between cells. Automatic valves can seal the filled cells, so that a punctured cell will not cause cells below and behind to deflate. A row or rows of cells can project below the base into a stabilizing trench. Cells can include internal or external rods or plates that support the horizontal structure. Embodiments can be initially filled with air, positioned, and then filled with water while the air escapes through a pressure valve. Barrier end structures can enable interlocking of adjacent units.

A flood barrier comprises hollow self-filling units (10, 12, 14, 16) placed end-to-end and connected at their ends by downwardly tapered bilobal (46) keys inserted into sockets (26, 28) at the ends of the units, wherein the keys incorporate concrete or other ballast for negative buoyancy.

A modular dike or barrier assembly includes straight and curved members that may be interconnected to form a barrier or dike wall surrounding a primary container. The members are hollow and include opposed side walls having integrally formed reinforcing ribs. The side walls extend at an acute angle relative to the base of the barrier to contain and redirect a surge flow directed toward the dike or barrier assembly. The interior surfaces of the side walls are closely spaced at locations spaced from the ribs and tend to abut for added wall reinforcement upon application of wall deflecting loads.
