Problems with Traditionel Flood Protection Systems

The dramatic pictures of recent flooding disasters both in Europe and elsewhere are prominent in the minds of everyone concerned with the topic of rising water levels.

The response teams will remember the scenes for a long time.

When extended high levels occur,  either through periods of long and heavy rainfall, melting snow or weather catastrophes, the following problems exist:

  • The response teams usually have a warning time of maxium 48 hours to plan precautionary action.
  • The floods cover a large area so that preparations for protection need to be made in many places at the same time.
  • The final height of the high water isn't calculable.

 

The load on man-power as well as the material expense are  the greatest challenges facing the response teams in a catastrophe.

Previous Experience

 

Sandbagging, which requires a huge amount of man-power and materials, has been employed in an effort to keep back the flood waters. In the case of flooding of over 30 - 40 cm however, this system reaches its limits. The bags often get washed away and cannot be replaced quickly enough.

The preparations for flood measures are simply too time consuming and complicated.

The assembly of a protection system must usually be made in bad weather which poses an additional burden for the teams. The water level usually rises faster than the protection barriers can be assembled resulting in the flooding of the areas to be protected.
