This model type has been distinguished as most promising related to model application in practice. The approach integrates the differentiated description of sustainable urban drainage systems (SUDS) as polygon geometries overlaying the basic data of a catchment. These overlays are defined with an additional functionality to receive and redistribute water within the model net. The user interface (UI) of the model provides a work flow allowing the user to build up and maintain models containing various types of SUDS. The model has been applied to assess the efficiency of SUDS and retention spaces to mitigate the flood peak discharge in several case study areas summarised in this paper. The results demonstrate the potential of green infrastructures (e.g. SUDS) and multipurpose retention spaces for flood peak mitigation.enhttp://rightsstatements.org/vocab/InC/1.0/GeowissenschaftenLandschaftsgestaltung, RaumplanungResearch Report10.15480/882.343510.15480/882.3435Kuo li cheng kung-ta hsüehOther
