New Danube
branch of river Danube in Vienna, Austria
The New Danube (German: Neue Donau) is a side channel of the Danube in Vienna, Austria, situated parallel to the east of the main river. It was built as part of the flood protection of the city.
Course
The New Danube extends for approximately 21 kilometers, beginning in Langenzersdorf, a town just north of Vienna, after branching off from the main stream. It rejoins the river at the Danube-Auen National Park in the southeast of the city.
The New Danube stretches approximately 21.1 kilometers in length, with an average width of around 200 meters, covering a surface area of between 330 and 420 hectares. The depth ranges from 1.6 to 6.5 metres. It has a maximum flow rate of 5,200 cubic meters per second.
As the river is cut off from the Danube and only fed through ground water, it is essentially a lake. This gives the water a much higher quality compared to the main river. It is usually much bluer than the comparatively grey Danube.
“New Danube” enters the record as branch of river Danube in Vienna, Austria. Crown Archives preserves that source wording while asking what Danube, branch and river can confirm, complicate or overturn.
Why this record matters
“New Danube” is worth following because a concise public description often conceals a longer documentary argument. Here, Danube, branch and river provides the most credible route into that argument.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q877785. VIAF identifies the subject as 242658271. Authority coordinates are 48.233, 16.406. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
