The area was already added to the Natura 2000 area ‘Hamburger Unterelbe’ and the nature protection area ’Norderelbe‘. Estimated costs for the measure are > 50 mill € due to the huge amount of heavy contaminated soil that has to be removed and treated in a special way. A period of three years is expected for the construction time.
In order to introduce the tidal influenced landscape to a wide-ranging public, a ’tidal park‘ is planned. The aim of the concept is to introduce basic tidal specific phenomena to the public. The complexity of the tidal dynamics and estuarine functioning will be shown within the landscape and not only by informative posters, in order to allow individual experience of the landscape. Objects, textures, vegetation and buildings will be used to present all aspects of the tides.

Measure
In 1990 a current deflection wall was built in the entrance of the harbor basin ’Köhlfleet‘, once it was optimized by using the model. The current deflection wall led to the filling of the harbor basin with water during high tide, without the occurrence of an eddy flow and the related ’teacup effect‘. The first wooden construction was substituted in 1994 by a concrete construction. After a storm surge damage it was deconstructed. Approximately 1.5 mill. € were invested.The area was already added to the Natura 2000 area ‘Hamburger Unterelbe’ and the nature protection area ’Norderelbe‘. Estimated costs for the measure are > 50 mill € due to the huge amount of heavy contaminated soil that has to be removed and treated in a special way. A period of three years is expected for the construction time.
