- Abstract
- The project ProBACH deals with the renaturation potential of Viennese urban water streams and carries out a comprehensive impact analysis. In urban, climatologically and socially neuralgic areas of the city, a test flow route is designed for the sectional reactivation and recreation of an open watercourse accompanied by planting. Sections of the former river course that have been preserved in the urban morphology will be described in types and serve as a basis for identifying suitable locations. For this purpose, variants of optimized solutions as well as potential obstacles, chances and risks are identified and verified on the basis of the Ottakringer Bach and other Viennese urban water streams verified on a test flow section. The project ProBACH develops a concept for an effective urban climate moderation as well as for the relief of the sewage system by an appropriate water management through the use of the open flowing stretch, doped with the existing stream water as well as the roof waters accumulating in the vicinity.
