A flood mitigation system comprises a number of barrier units connected end-to-end to form a flood barrier wall wherein each individual barrier unit includes gripping structure along a bottom wall to resist dislocation when impacted by flood water and floating debris and a seal is placed on an end wall of each barrier unit so that the barrier wall resists leakage of flood water between adjacent units.

A portable, water-filled barrier system includes a plurality of water-fillable modules, each module being internally divided into cells that emulate a section of a sandbag dike or wall. Automatic valves can seal openings between the filled cells, so that a punctured cell will not cause cells below and behind to deflate. A manifold can be used to simultaneously fill a plurality of modules. The barrier system further includes at least one anchoring support base having an underlying portion that extends under at least one of the modules. A vertical portion of the support base extends upward behind and abuts at least one of the modules, and an anchoring portion includes openings that enable attachment of the anchoring support base to the underlying ground by stakes and/or spikes. A flexible sheet can be installed beneath and in front of the assembled barrier to further inhibit horizontal displacement of the modules.

Methods, systems, and computer programs are presented for a flood-recovery analysis tool. One method includes operations for generating a prediction of water depth in a geographical region based on weather data for the geographical region and topography data for the geographical region, and causing presentation of a flood inundation map showing the prediction of water depth in a user interface of a display device. The user interface includes an option for entering flood mitigation measures. Further, the method includes operations for receiving the flood mitigation measures via the user interface, updating the topography data to include the received flood mitigation measures, and generating an updated prediction of the water depth in the geographical region based on the updated topography data. An updated flood inundation map is presented in the user interface showing the updated prediction of the water depth and a geographical location of the flood mitigation measures.

An inflatable water barrier assembly includes a plurality of boundary units. Each of the boundary units can be linked together on a support surface to define a boundary around a selected area to inhibit flood water from entering the selected area. Each of the boundary units has a lower portion that is fluidly discrete from an upper portion. The lower portion is fillable with water to weighing down the boundary units. The upper portion of each of the boundary units is inflatable with air to inhibit the flood water from passing thereover. A plurality of anchors is engages a respective one of the boundary units. Each of the anchors penetrates a support surface to inhibit the respective boundary unit from being moved by flood water.

A bottom boom and method of use is disclosed for containing heavy or sinking oils which migrate on an underwater floor. The bottom boom is comprised of an upper wall, a lower wall that abuts an underwater floor, a support structure and a ballast section. The upper wall and lower wall when properly supported by support structure provides an upright barrier to guide or stop heavy non-floating oils on an underwater floor. The support structure is a series of chambers, longitudinally spaced between the upper and lower walls of the bottom boom, such that when each chamber is filled with water the chambers vertically support the upper wall at an angle above the lower wall and horizontally maintain the lower walls width thus forming said upright barrier. Additionally the chambers can be filled with air to expedite recovery of bottom boom from underwater floor.

A ground sealing arrangement for a portable flood barrier to be positioned on the ground includes a vertical wall and a main sealing layer forming a main body. The main sealing layer is impermeable to water. The ground sealing arrangement further includes a bottom sealing layer arranged on a ground-facing underside of the main sealing layer. The bottom sealing layer is attached to the main sealing layer at a distance from a peripheral edge of the main sealing layer that is most distal from the first edge of the ground sealing arrangement such that the bottom sealing layer has a free end extending from the point where the bottom sealing layer attaches to the main sealing layer towards the peripheral edge of the main sealing layer, and comprises a highly flexible and/or glutinous material which is stretchable and sticks to the ground when the material is soaked with water.

A reservoir bag and method of use and implementation is disclosed herein. The reservoir bag may be configured for controlling surface water run-off and may include a plurality of cells with at least two adjacent cells in fluid communication with each other to allow water to communicate between the adjacent cells. To aid in the mobility of water, the bag may include one or more perforated pipes therein to direct flow of water through the cells and to an outlet.

A flood control system is provided that allows an unobstructed view of the surrounding area when not in use. The flood control system comprises a base and at least one foundation coupled to the base. The base is positioned below a grade to protect an area from the encroachment of fluid or semi-solids. An expandable barrier is removably coupled to a channel in the base. The expandable barrier is inflated with a source of pressurized fluid to form a barrier to prevent the encroachment of fluid or semi-solids to the protected area.

A system and method for deployable barrier, deployed along a surface that can include: a receptacle that includes a set of walls that are at least partially made of a flexible material and that define at least one sub-channel extending along a length of the receptacle, and the receptacle comprising an inlet to the at least one sub-channel; wherein the receptacle can be arranged in a collapsed configuration; and a filler material that when introduced into the at least one sub-channel through the inlet expands the receptacle into a deployed configuration and thereby forming a barrier with an expanded form. The deployable barrier can have applications and customized features for fire containment and mitigation, flood containment, and/or other applications.

A bio-friendly water flow control system can include a portable structure adapted to contain organic waste material. The water flow control system can be configured for deployment outdoors to guide water flow to limit erosion. A portable structure of such a system can include a sheath that is configured to contain waste material within an interior of the sheath. The portable structure may be configured to allow a flow of water into the interior of the sheath. The portable structure may include a waste material that includes processed palm frond particles. The portable structure may be configured to absorb a weight of water at least 50% greater than a dry weight of the portable structure.
