A flood protection system and a method of using such a system. The system includes at least one elongated flexible tube arranged for being filled with and containing a fluid, wherein the at least one flexible tube comprises a number of positioning elements.

Flexible containment tubes form sections of a dike for fluid containment. Structural supports are inserted into the flexible contain tubes and the tube sealed to form structure supported dike sections. For example, a supporting structure may be configured with a given length and cross sectional diameter to provide structural support to a vinyl-coated polyester tube with a 12-36 inch diameter. The structure is sealed within the tube and, in turn, the tube may be filled with a fluid such as water to create structure supported containment dike. The length of the supporting structure may be selected based on the width of an entryway to create structure supported dike section of a give length that provide a seal across the entryways against floodwaters.

An erosion control apparatus is disclosed herein comprising a filtering member defining a looped portion; a guide member positioned within the looped portion of the filtering member; and a support member insertable in the looped portion of the filtering member. The guide member facilitates insertion of the support member into the looped portion of the filtering member.

The present invention is a rapidly deployable flood defense system and method that has at least one barrier cover, each comprising a plurality of laterally-extending crossbeam housing tubes stacked generally vertically and housing an inflatable crossbeam disposed within the tube, an end retaining tab at each end of the tube, and a plurality of rear support retaining tabs spaced along the lateral length of the crossbeam housing tube; and a front apron and a rear apron. The system also has a plurality of support tubes and a plurality of additional support tubes positioned along the lateral length of the crossbeam housing tube. Each support tube held in the generally vertical direction by a base post and each and additional support tube positioned along the lateral length of the crossbeam housing tube having an additional base post positioned rearwardly.

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 supported by a hollow frame including a base below the module and a rear wall behind the module. Holes allow flood water to enter the frame's interior. A peripheral base rim can surround and restrain the module. At least one brace can extend from behind the rear wall of the frame to underlying terrain, where it can be wedged or staked in place. The frame can be unitary or can comprise separate base and rear wall constructions that can be assembled to form the frame, for example by inserting a portion of one into a trough provided in the other. A fitting can extend between the assembled base and rear wall to allow water to flow between the hollow interiors.

A sack for realising civil engineering works, including a sack structure with two main faces defined by two respective equal main areas of cloth that are joined over most of their periphery. The main areas of cloth define an opening for introducing filling material into the sack structure when in use. The sack includes at least one area of protective cloth whose resistance characteristics differ from the main areas of cloth. The area of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.

A flood control system that is configured to be deployed so as to control floodwaters wherein the flood control system is provided in multi-cell configurations of modular receptacles. The flood control system includes a plurality of modular receptacles having four walls wherein the four walls are movably coupled so as to transition intermediate a folded position and a deployed position. The walls of the flood control system include a plurality of apertures and corner structures that are helical coil in shape. A locking pin is provided to be operably coupled intermediate modular receptacles so as to provide a mechanical connection therebetween. A liner is disposed within the interior volume of the modular receptacles and is mateable shaped therewith. A lid member is further included and is operable to cover the plurality of modular receptacles. The lid member further includes locking aperture rows so as to inhibit access.

An apparatus for impeding beach erosion includes a sea-facing barrier wall penetrated by large holes that allow water mixed with sand to enter the apparatus. Smaller holes provided in a rear wall allow the water to drain out after the entrained sand has settled. An underlying water reservoir fills with the drained water and gravitationally anchors the apparatus. The reservoir can be buried in the sand or placed on top thereof. The top of the barrier wall can be curved to direct water back toward the sea. The barrier wall can extend above the rear wall, and a backstop wall can form an additional sand-collecting chamber behind the rear wall. The walls can be made from 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.

A flood prevention device includes a gate device constituting a passage between a flood prevention area and an outside area, and a portable flood prevention material that separates the flood prevention area and the outside area with the gate device. The gate device has a side wall corresponding to one end of the portable flood prevention material.

A sand bag filling device comprises a trailer having a foldable post with a distribution head at a top of the vertical post. This distribution head is attached to a plurality of filling spouts which extend downwardly and outwardly from the head to positions surrounding the head. A rotatable chute is positioned at the top of the head for receiving sand from a conveyor and for supplying that sand to each in turn of the filling spouts. The post is formed in three portions each pivotally movable relative to the next, with an intermediate post portion pivotally hinged to a top and a bottom post portion at diametrically opposite sides of the post. The filling spouts are attached via readily releasable couplings to funnels communicating the rotatable chute in appropriate position therewith. There may be up to 18 to 24 spouts.
