Fixing the Estuary: The Tidal Elbe ConceptFixing the Estuary: The Tidal Elbe Concept
Three Cornerstones for a Future Action Plan:
1. Attenuation of Tidal Energythrough River Engineering i th M thin the Mouth,
2. More Room for the River (Tidal2006 Volume) in the upper Part
3. Optimisation of the Sediment-

Advanced intention of the project
T i l t l ti th tTo implement a solution that
• includes all needs on-site (residents, nature and water conservation, recreational uses tidal river development and consequences of climaterecreational uses, tidal river development and consequences of climatechange, etc.),
• brings out a macroeconomicly reasonable and ecological handling of theupcoming soil
• makes the interaction of tidal action and nature visible for the broaderpublic in a positive way
• is suitable for the communication of the tidal Elbe concept in general.
