Issue

Flood hazard

An increased flood hazard because the flood defence does not meet the requirements and/or due to extreme conditions.

Climate change and its effects, such as sea level rise, cause an increasing threat of floods. Due to lack of space, conventional flood barriers can not be implemented.

Solution

eXtra

eXtra is a self-closing flood barrier, powered by water pressure. Rising water will make the barriers panels float up creating a wall that blocks the water. The barrier exists of multiple modules that will float up in succession, depending on the water level. With each extra module the height of the barrier increases. This process continues depending on the number of modules and/or the water level.

eXTRa

Pros

  • Completely automatic.
  • By using multiple modules, a relatively high wall can be created from a relatively shallow basin.
