The production of pluval flood hazard maps have became increasingly important in recent years. In contrast to fluvial flood hazard modelling a more detailed consideration of small surface structures and permeable structures have large relevance for pluvial hazard simulation, because they have a significant influence to runoff processes. Additionally, infrastructure facilities like bridges, tunnels and even large individual buildings are of particular importance, when drainage take place on several height levels which might be connected with each other. Commonly, hydraulic 2D models only allow one level of flow, therefore individual solution approaches have to be developed. Three examples will be elaborated in this paper how model design can meet such requirements in practice. The examples are taken from pluvial flood risk management projects in different regions of Germany, also considering various data availability and quality.
