Device design

Dryup has created a device to protect people, their property and the infrastructures. It operates without energy or human intervention and with minimal maintenance.

It is a dike hidden in the ground between the area to be protected and the flooded river. By the principle of Archimedes, the rising waters deploy it above the natural terrain; this consists of a temporary protective structure.

In addition, the height of the device would be adapted according to the configuration of the site and the flood scenarios.

The advantages of the device:

• Its geometry and its mechanism not vulnerable to sand, gravel, and floating debris.
• It has no visual impact, except during flooding, and is not an obstacle to mobility.
• It can be used for other purposes; for example, cycle paths.
• It remains stable, even in the event of exceptional water spillage.
• Its foundations would not suffer any erosion or scour.
• It can moderate rising waters, if placed far from the banks, by allowing an expansion of the flood surface.
• If connected to other systems, it can form a coherent protection system, especially in urban areas.
• It can use, after a flood, the circulation of water from the river in its channel, to facilitate the evacuation of deposits.
• It has top access if manual removal is required.
• It requires little maintenance.
