A portable, water-filled barrier system includes a plurality of water-fillable modules, each module being internally divided into cells that emulates a section of a sandbag dike or wall. Adjacent modules are interconnected by fastening mechanisms, such as loops attached to fronts or sides of the modules and connected by straps or clamps. Automatic valves can seal openings between the filled cells, so that a punctured cell will not cause cells below and behind to deflate. In embodiments, the barrier can be initially filled with air, positioned, and then filled with water while the air escapes through a pressure valve. A manifold can be used to simultaneously fill a plurality of cells. A flexible sheet can be installed beneath and in front of the assembled barrier so as to inhibit leakage of water under or between the cells.

High-density bales for erosion control or for forming a flood barrier are made by the compaction of tree leave material. The bales are made substantially from tree leave material that retains at least a portion of the vein structure. The vein structure improves the structurally integrity of the bale. A baler may be used to form the bale and it may compact the leave material up to an 8:1 compaction ratio, forming bales with a density of 0.3 to 0.8g/cc or more. The bales may have a retainer wire or mesh configured around a portion of the bale to retain the bale shape. The bales may contain seeds for growing plants directly from the bales as the leave material degrades to provide the nutrients for plant growth. This plant growth from the bale provides an aesthetically appealing bale that blends into the natural environment.

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.

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.

The absorption device includes a hydrophilic powder and a casing which is permeable to a liquid, the casing being composed of an upper layer which is superimposed on a lower layer, the lower and upper layers being connected to each other by strong connections which delimit a confinement zone for the hydrophilic powder in the casing. Advantageously, the lower and upper layers are connected to each other by first weak connections. The first weak connections delimit a plurality of adjacent cells in the confinement zone, each cell enclosing a quantity of hydrophilic powder sufficient to bring about the breakage of the first weak connections which delimit the cell when the hydrophilic powder absorbs a liquid.

Provided is a multiplex water cutoff wall with a simple structure that can control water infiltration into an interior by way of being provided with multiple water cutoff walls and having a configuration to drain water having infiltrated between the water cutoff walls with a drainage means such as a pump. A plurality of water cutoff walls 1A, 1B, 1C, 1D are disposed in a multiplex configuration with gaps in the wall thickness direction. Drain pumps 4a, 4b, 4c are provided as the drainage means for discharging water having infiltrated between the water cutoff walls 1A, 1B, 1C, 1D to the outside. Water that has infiltrated between the water cutoff walls 1A and 1B when a rise in water level is caused outside the multiplex water cutoff wall during flooding is discharged to the outside of the multiplex water cutoff wall by the drain pump 4a. If necessary, the water cutoff wall can be arranged into a multiplex configuration with a third water cutoff wall 1C and a fourth water cutoff wall 1D, and water infiltrating therebetween is discharged with the drain pumps 4b, 4c. Thus, the level of infiltrating water is lower nearer the interior, and water flood damage can be prevented to a structure in the interior protected by the multiplex water cutoff wall.

Disclosed is a protective barrier segment for a temporary liquid-damming protective barrier configured for separating a flooded side from a protected side by abutting against a ground surface, the protective barrier segment including a liquid-damming member having a first surface facing the flooded side and a second surface facing the protected side. The protective barrier segment is characterized in that the liquid-damming member includes an opening connecting the flooded side and the protected side and in that the protective barrier segment further includes a pump arrangement, wherein the pump arrangement is located at the opening in sealed engagement with the liquid-damming member and wherein the pump arrangement, in use, pumps liquid from the protected side to the flooded side. Also disclosed is a protective barrier including such a protective barrier segment.

A flood barrier to protect an area of land from floodwaters, the flood barrier having a waterside to be placed adjacent a body of water and a protected side opposing the waterside, the flood barrier comprising a plurality of supports spaced apart from one another; at least one intermediate barrier section supported to extend between a pair of neighbouring supports when assembled, the intermediate barrier section comprising at least a first beam arrangeable such that it is supported to extend between the corresponding pair of neighbouring supports and a water impermeable membrane sheet attachable to said first beam via a mechanical connection to form a skirt extending from said first beam, outwardly from the waterside of the flood barrier onto the ground.

The present invention relates to a water barrier module system comprising a first (10) and a second (20) protective module configured to form at least a part of a water barrier. Each protective module comprises a side flange (12, 22) extending substantially perpendicular to a main plane and having an outer surface (18, 28) and an inner surface (16, 26). Each of the side flanges comprises at least one elongated opening (14, 24) having a width (W2) and a length (L2), wherein the length is larger than the width. A connection device (30) is configured to, in a connecting position, connect the side flanges (12, 22) by extending through the elongated openings when the outer surfaces of the two side flanges are arranged to each other. The connection device (30) comprises a first portion (31) configured to abut the inner surface of the first side flange, and a second portion (32) configured to abut the inner surface of the second side flange. The first portion (31) of the connection device has a width (W3) that is smaller or equal to the width (W2) of the elongated openings (14, 24) and a length (L3) that is larger than the width (W2) of the elongated openings and smaller than or equal to the length (L2) of the elongated openings.
