Multiple pressures as urbanization, densification and climate change lead to the need for adaptation of sewer systems within urban environments. To increase the adaptive capacity of stormwater management systems, there is a shift towards decentralized nature-based solutions (NBS). Especially in densely built areas the availability of land can be a limiting factor for the implementation of NBS. To consider the spatial framework conditions in planning we developed an integrated modelling framework for prioritizing sites for NBS implementation for stormwater management within built urban structures. The implementation potential of NBS from a settlement structure model and a street typology model are combined with the discharge reduction potential from a sewer model. In effectiveness matrices priorities for stormwater management sites for individual NBS are identified. This modelling framework offers a transparent and flexible approach to decision making for the implementation of NBS.
城市化、人口密集化和气候变化带来的多重压力，导致城市环境中的下水道系统需要适应。为了提高雨水管理系统的适应能力，人们正在转向分散的基于自然的解决方案（NBS）。特别是在人口密集的地区，土地的可用性可能成为实施 NBS 的限制因素。为了在规划中考虑空间框架条件，我们开发了一个综合建模框架，用于为城市建筑结构内的雨水管理确定 NBS 实施的优先地点。从一个住区结构模型和街道类型模型中获取 NBS 的实施潜力，并结合下水道模型中的减排潜力。在有效性矩阵中，确定了各个 NBS 的雨水管理地点的优先级。该建模框架为 NBS 的实施提供了一种透明和灵活的决策方法。
