Tubebarrier

The Tubebarrier is a temporary ood defence; quick and easy to deploy to prevent ooding of water in urban and rural environments As well in case of industrial leakage/seepage or temporary water storage.

Which hazard(s) is the innovation designed to mitigate?

Fluvial oods: resulting from discharges that exceed ood protection levels; the high-river discharges are caused by heavy precipitation in the river basin.

Heavy local precipitation (rainfall events): results in 1) (urban) oods due to exceedance of drainage capacity, and 2) ash oods, dened as rapid ooding of low-lying areas, generally within a few hours after heavy rainfall events such as thunderstorms.

How does the innovation work?

The Tubebarrier is an innovative temporary exible ood barrier that can be installed without the use of electricity, pumps, compressed air and / or a lot of manpower The Tubebarrier consists of elements of 10 meters that can easily be connected to each other, by a special design zipper, making the temporary dike as long as necessary

The principle is that we use the upcoming water from the ood to stop the same water So "Fighting water with water".

The Tube consists of a hollow tunnel that is held up by reinforcing slats, with a stability ap in front of it. When the water rises, the water runs on the ap and also in the Tube itself, because there are inlet holes at the bottom of the Tube. Due to the weight and therefore the pressure of the water, the Tubebarrier gets its stability The innovation works through so-called communicating vessels: when the water is high the tube lls up and as soon as the water is gone the tube empties itself

The Tubebarrier is capable for overow (not turning over once the water reaches a level higher than its capacity), which increases the safeguarding properties The Tubebarrier is stored like an accordion (compact) and installed quick with a short installation guideline. The barrier is xed into the ground with ground plates or anchors (depends on the surface), and operates independent from electricity After usage, the Tubebarrier can be folded back together in the box and easily be transported to a storage facility for reusing This way 100 meter Tubebarrier can fold back to 6 meter Added value / main differentiating element from conventional approach(es)

Quickly to deploy (100 m/hr with 4 people) and to remove. Cheap, efcient and secure. Alternatives are slower, more difcult to organize during times of oods and less exible for different surface conditions.

Critical success factors

Success factors: www.tubebarrier.com

- Quick to place; installation doesn't need much people and equipment.

- Relatively cheap; for installation of a permanent ood defence is more complex.

- Reusable; can be used more than once.

- Multi-use on different locations; one Tubebarrier can be used at multiple locations.
