According to the present invention there is provided a liquid retention device comprising: a braced frame mountable on foundations in a plurality of locations, in which said device comprises a base section and at least one upstanding support, and in which said brace further comprises height-adjusting means for adjusting the height of said frame, and in which said device further comprises a face supported by said frame, in which said face is inclined at an angle to the at least one upstanding support, wherein said face is covered by a least one detachable mat.

The present invention provides a panel, a flood control assembly, a flood control device and a flood control barrier.

The invention relates to improved water control gates and related inflatable actuators, and associated sealing, manufacture and operation apparatus and methods. Advancements in technologies related to air fitting design, inflated bladder stress relief, inflatable bladder strength enhancement, water gate related slide friction mitigation, abutment and other impounded water seals, gate panel fabrication, traffic accommodating water impoundment structures, and water gate panel system operation efficiency, as well as nappe aeration, hinges, and bladder manufacture technology are disclosed herein.

This disclosure provides methods, systems, and kits for building seawalls using mechanically interlocking blocks. The interlocking blocks have interiors that can be filled with sand, gravel, or cementitious material after formation of a wall. The interlocking blocks that can be connected on any side to form a structure, wall, foundation, floor, building, flotation device, gardening structure, or toy. The interlocking blocks typically comprise center openings and connecting openings on each side and can be connected with hardware through the connecting openings. The center openings allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked blocks. Connected blocks can also be filled with fortifying material to strengthen the structure. Sides of connected blocks can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connectors for connecting sides of the interlocking blocks.

A multi-part reusable retaining wall and levee bag. The reusable levee bag includes a top bag section and a bottom bag portion removably affixed to the top bag portion. The combined top bag section and bottom bag portion define an interior space within which fillable material may be received to form a levee bag for use in flooding and other installations. The bottom bag section includes a receiving cell for receiving an end of another levee bag to connect multiple levee bags end to end to form a retaining wall with minimal gaps between levee bags. The bottom bag section is made of a biodegradable material while the top bag section is made of an alternative material. The reusable levee bag, once filled, may be disassembled and the top bag section reused while the bottom bag section may remain in place to biodegrade.

A portable, water-filled barrier system includes a water-fillable module that is internally divided into cells that emulate a section of a sandbag dike or wall, the module being fixed to an underlying base having front and rear boundaries that extend up from base and horizontally restrain the module. The base can be flexible and water filled, or rigid, and can be installed at or below grade. A lid can extend between the front and rear boundaries of a rigid base to cover the unfilled module, enabling the assemblies to be stacked when stored and transported. The lid can be hinged and, when open, can be supported by at least one brace extending from behind the lid to underlying terrain, where it can be wedged or staked in place. Adjacent bases can be joined at the front and rear to maintain contact between adjacent modules.

A walkway for use between a shoreline of a body of water and at least a portion of a building exposed to the body of water, the walkway including: a base adjacent to the building; a plank having a surface for use by pedestrians to walk upon when the plank is in a first position at least indirectly disposed on the base, the plank having a first end rotatably connected to the base and having a second end extending from the first end away from the building along a length of the plank, the surface being exposed for use by the pedestrians to walk upon when the plank is in the first position; and a lifting mechanism operatively connected to the plank to rotate the plank from the first position to a second position where the length of the plank is oriented adjacent to a wall of the building to impede a rising height of the body of water.

A ground-anchored foundation for a mobile flood protection arrangement is provided, wherein the ground-anchored foundation comprises at least one bottom anchor cylinder, wherein the at least one cylinder is attached to a plate, the plate being centered to the at least one cylinder, wherein the plate comprises a mounting hole adapted for pivotally attaching a receiver part to the mobile flood protection arrangement.

A flood barrier component comprising a base; a plurality of wall extending upwardly from the base; a top coupled to an upper edge of said plurality of walls and defining a cavity between said base, plurality of walls and said top; the top or the at least one of said plurality of sides to be placed in contact with the flood waters being capable of allowing the flood waters to pass through the top or the at least one of said plurality of sides into the interior of the flood barrier component and being retained therein.
