Hohenwischer Brack
The Hohenwischer Brack is a brackish in the Hamburg district of Francop . It was created when the dam broke during the storm surge in 1962 . The official name of the geotope is Flutbrack Hohenwisch .
Location and description
The Hohenwischer Brack is a water-filled scouring area on the banks of the Alte Süderelbe . It is located on the corner of Hohenwischer Strasse and Hinterdeich in Hamburg-Francop. The brackish is 0.7 hectares and is 2 meters above sea level . Its subsoil consists of Holocene sand, above which is a three-meter-high layer of peat and clay .
The area at Brack is used as a park and memorial.
history
The Hohenwischer Brack is the youngest brack in the Elbmarsch created by a dike breach . It was created by the storm surge on February 17, 1962 , whereby a dike over 80 meters wide was destroyed and a 10.7 meter deep scour formed. 26,900 cubic meters of soil was eroded and mostly deposited in an alluvial fan 800 meters long and 400 meters wide .
In March 1962 a working group of the Institute for Geography at the University of Hamburg mapped the Hohenwischer Brack.
In 2002, on the occasion of the 40th anniversary of the flood disaster, a wave-like memorial created by the Moorburg sculptor Winni Schaak was erected.
meaning
A special feature of the Hohenwischer Brack is that its formation and original form, unlike many others, is precisely documented. It is one of the eight geotopes of a total of 32 geotopes in Hamburg that are classified as nationally significant .
