Local reactivation of Viennese urban streams supported by nature-based stormwater management (ProBACH)
Funded by
Austrian Research Promotion Agency, Sensengasse 1, 1090 Wien, Austria
he ProBACH project deals with the potential for renaturation and a comprehensive analysis of the impact of Wienerwald streams. 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 are described in types and serve as a basis for identifying suitable locations. For this purpose, variants of optimised solutions as well as potential obstacles, opportunities and risks are identified using the Ottakringer Bach and other Wienerwald streams as examples and verified on a test flow section. The ProBACH project is developing a concept for effective urban climate moderation and for relieving the burden on the sewage system through appropriate water management by using the open flow section, doped with the existing stream water and the roof water accumulating in the vicinity.
