Abstract: The application of blue and green infrastructure in urban stormwater management has attracted increasing interest in recent years. At the same time, one can observe a heavy modification of urban watercourses by land reclamation measures aiming at canalizing, straightening, and draining existing water systems at many places around the world. In the context of sustainable urban development, the question arises, whether the reactivation of former watercourses could be an additional option to support urban stormwater management. This article introduces a process to identify former watercourses and to pre-assess their suitability to support urban stormwater management considering different hydraulic functionalities and stormwater related criteria. To prove the practicability of the approach, it was applied in a case study. Our investigations revealed that the reactivation of former watercourses can provide additional opportunities towards more nature-based and sustainable stormwater management in the urban fabric.
