New Danube

The New Danube is a side channel built in 1972–88 on the eastern side of the Danube in Vienna, Austria. It was created to provide flood relief by containing excess water. The Donauinsel, made out of the removed material, separates the new waterway from the main channel of the river. The project was referred to by the United Nations Human Settlements Programme as "the first truly multipurpose fully sustainable flood protection scheme."The New Danube flows parallel to the river for approximately 21 kilometres through the Vienna metropolitan area.
