Branch channel

from Wikipedia, the free encyclopedia

The term branch duct generally refers to a branch from an existing duct system. Traditionally, both branches from an above-ground sewer (branch sewer ) and from an underground (sewer) sewer are referred to equally.

Waterways

Britzer Zweigkanal (January 1950)

Above-ground branch canals are being built to expand the inland shipping routes . For example, the Linden branch canal connects the Linden harbor with the Mittelland Canal . Further examples of branch canals are the branch canal (Dortmund-Ems canal) , the Magdeburg canal , the Osnabrück canal , the canal III3b and canal III C , the Britzer canal and the Kembs-Niffer canal . (→ for further examples see also branch sewer and list of branch sewers in Germany )

Boundary marking

Branch channels, like natural waters, can also mark boundaries. One example is the Britzer Zweigkanal , which was built before the division of Germany (in the German Empire 1900–1906) and which later marked part of the border between the former east and west of Berlin.

Sewerage

Branch channels of underground channels are used, for example, to discharge sewage or to ventilate the sewer system.

Water supply

The term is used both for above-ground canals to improve an existing irrigation system, as well as for (at least partially underground) pipes for water supply. Both the Incas and the Romans used this technique in historical times .
