A connection system for connecting at least one membrane to a rigid support, the connection system comprising: at least one elongated clamping profile, at least one locking unit configured for attaching the at least one elongated clamping profile to the rigid support, thereby clamping a portion of the at least one membrane between the at least one elongated clamping profile and the rigid support so as to achieve a sealing between the at least one membrane and the rigid support, wherein the at least one locking unit is a discrete state locking unit movable between several predetermined locking unit states, each locking unit state corresponding to a connection system stage, the predetermined locking unit states including: an Open locking unit state in which the locking unit is configured to provide a gap between the elongated clamping profile and the rigid support, allowing the portion of the at least one membrane to be inserted between the elongated clamping profile and the rigid support, the Open locking unit state corresponding to an Open stage of the connection system, a Closed locking unit state in which the locking unit is configured to press the clamping profile toward the rigid support so that the at least one membrane is clamped between the elongated clamping profile and the rigid support, the Closed locking unit state corresponding to a Closed stage of the connection system in which a sealing is provided between the at least one membrane and the rigid support, and an Intermediate locking unit state between the Open locking unit state and the Closed locking unit state, in which Intermediate state the at least one membrane is allowed to slide along the elongated clamping profile without disengaging therefrom, corresponding to an Adjustment stage of the connection system.

Provided is a flood barrier for use with HAZMAT materials. The barrier includes a first wall and a second wall joined together at a first end, tape for securing the barrier to a surface to prevent leaks, multiple flexible ribs attached between the first wall and second walls, one or more holes for filling, and a rod that separates an open end of the first and second wall to form a chamber with an open end. Several insulating floats are evenly spaced between the ribs on a bottom surface of the first wall to prevent overflow. A gap filler, such as uncured silicone and tape is used in the transition from a terminal rib to an exposed corner of the barrier. The barrier can withstand high heat for a sustained period of time, is leak-proof, and includes an improved method of sealing corners.

An interlocking modular smart seawall diversion and recreation system provides step-shaped diverter sections arranged side-by-side along a shoreline. The diverter sections slope from a base end up towards an upper end. To break kinetic energy of waves, and divert waves, the diverter sections form steps with curved risers and horizontal treads. The system forms a diversion path for the waves that reach the upper end of the modular walls and recirculate the wave energy back to divertor chamber and natural environment. Foundation pilings project into the ground and extend up to support the wall sections. The bottom end of foundation pilings terminates at sheared attachments having a tapered cross section and an edge for securely anchoring into the ground. A platform atop the diverter sections provides a pathway; a lighted platform for recreational activities; and transparent skylight portals for observing aquatic wildlife in water below and creating an indigenous ecosystem.

A water flow control device is provided that opens to allow water to leave a basin and pour into another pool of water. The water flow control device closes when the level in the pool of water is such that an influx of water could be returned to the basin. The water flow control device has a buoyancy apparatus that opens and closes the water flow control device based upon the level in the pool of water. The water flow control device also has a conveyance channel apparatus that directs water from the basin through the water flow control device in the event the buoyancy apparatus provides an opening to do so.

Embodiments herein relate to a ground sealing arrangement for a portable flood barrier further comprising a vertical wall. The ground sealing arrangement is arranged to be positioned on the ground. The ground sealing arrangement comprises a main sealing layer forming a main body of the ground sealing arrangement. The main sealing layer is impermeable to water. The ground sealing arrangement further comprises 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 L from a peripheral edge of the main sealing layer which 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 flood mitigation barrier comprising a line of central structures wrapped in a flexible heat shrinkable polymer material. The polymer material is configured such that when heat is applied to the material, shrinks to conform around the central structures.

Systems and methods are disclosed for coastal resiliency amelioration or other flooding amelioration, comprising adding a layer of foamed glass aggregates to a property to raise its elevation, wherein the surcharge on an underlying soil of the property is not increased. In some embodiments, the surcharge on an underlying soil of the property is decreased (e.g., a negative surcharge). Systems and methods are also disclosed for increasing the stormwater storage capacity of a property, comprising, adding a layer of foamed glass aggregates to the property.

This invention provides a method and system for abating flooding that uses retention or detention ponds that require less surface area than prior art methods. The invention comprises at least one deep but narrow pond or water storage basin that can be pumped down during non-flood periods to an adjacent or remote water body. In one embodiment, the invention further comprises a levee to forms part or all of the water storage basin. The water levels in the water storage basin are controlled through a series of sensors, gauges, and/or valves either manually or automatically both for flow coming into the water storage basin during peak levels in an adjacent or remote water body and after peak elevations.

A flood barrier for protecting the environment having a venturi type effect pumping means not requiring external power, the flood barrier comprising a wall and a pump for drawing water across the barrier from a first side to a second side. The wall configured to provide a barrier preventing movement of water from the first, drain, side to the second, tributary, side, of that wall. The barrier further comprising a pipe traversing the wall for transferring water between the two sides of the wall the pipe being terminated in the first side of the wall at a venturi effect pump, the pump being feedable with water from the drain through a conduit inlet so as to create suction in the pipe for drawing water through the pipe from the second side of the wall to drain water from the second to the first side of the wall.
