Flexible containment tubes form sections of a dike for fluid containment. For example, multiple vinyl-coated polyester tubes with a 19-inch diameter may be filled with water and stacked on top of each other to create a temporary diversion dike. Multiple sections of dike may be abutted together to form longer sections of dike. A vapor barrier or plastic membrane may wrap over dike sections and/or weaved through the flexible containment tubes as they are placed prior to filling. Configurations of the vapor barrier and associated anchoring mechanisms improve the utility of dike sections by reducing hydrostatic pressure of contained fluid on the dike, harnessing the weight of fluid columns, and mitigating seepage through the dike sections.

A flood barrier module that is light, easy to install, easy to remove or stow, and resistant to softening of underlying ground includes an inclined front wall penetrated by holes near a top thereof, as well as side walls, a rear wall, and a base wall, which together surround a substantially watertight interior. The module is initially anchored by its own weight and/or by stakes or similar means. When impacted by flood waters that rise higher than the holes, the module is filled with flood water that is retained within the interior, such that the weight of the retained water anchors it to the ground, even if the ground becomes softened. Embodiments can be folded or disassembled and stacked into a flat, stowed configuration. The module can be installed in a sump or pit, and can be at or below grade when stowed.

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 modular building block apparatus for the construction of a coastal or river bank erosion defence or protection structure includes a plurality of blocks arranged in stacked rows, the blocks in each row having cooperating formations whereby the blocks in each row are interconnected with one another. Apertures formed in each block extend perpendicular to the rows, and a plurality of connector members extend through aligned apertures in adjacent rows of the blocks to interlock the rows to one another.

A barrier structure for impeding erosion due to mudslides allows mud to enter through large holes in a barrier wall, and water separated from soil to drain out through smaller holes in a rear wall. An underlying reservoir can further stabilize the structure by rapidly collect water and/or mud. A backstop wall and/or an extension can be abutted to a top of the barrier wall to enhance mud collection during a mudslide. The structure can further include a penetrating passage enabling a fraction of impacting mud to flow through unimpeded, and/or a diverting wedge uphill of the apparatus diverts some impacting mud and debris while allowing a remainder thereof to pass through to the barrier wall. A plurality of the barrier structures can be installed such that mud flowing past an uphill structure impacts a downhill structure. The barrier structure can be constructed from biodegradable materials.

A system for impeding shore erosion includes a sea-facing barrier wall penetrated by large holes that allow water with entrained sand to enter the apparatus. Smaller holes provided in a rear wall allow the water to drain into an underlying reservoir after the entrained sand has settled. An extension can be abutted to a top of the barrier wall to enhance sand collection during a storm. Water that flows over the barrier wall is caused to flow over a top of the extension, whereby water with entrained sand falls through openings in the extension top. Sand collected by the extension remains on the shore when the extension is removed. The apparatus can include plywood, metal, or plastic. Embodiments can be disassembled and/or folded for transport and storage. Internal reinforcing partition walls can extend between the barrier and rear walls. The apparatus can be further anchored by stakes.
