Climate change enhances pluvial flood risk in many cities all over the world, especially in densely populated urban areas with high impervious surfaces that need to adapt to heavy precipitation. For this purpose, multifunctional stormwater infrastructures such as water plazas appear promising as there is a high competition for open space in most urban areas. Yet, to date only very few water plazas have been realized with at least one implementation hampered by a lack of public acceptance. In this study, semi-structured interviews are used to investigate how plans to build a water plaza in the city of Cologne are perceived by local residents. Factors crucial to public acceptance are identified. Experience with flooding, knowledge of the planned construction and awareness of benefits turned out to be important for acceptance, whereas social and personal norms were less relevant. The identified factors led to finding recommendations to promote public acceptance of innovative climate adaptation measures like water plazas.

了解多功能水广场的公众接受度：一个案例研究

气候变化增加了全世界许多城市的洪水泛滥风险，特别是在人口稠密，地表不透水，需要适应强降水的城市地区。为此，多功能雨水基础设施（例如水广场）似乎很有希望，因为大多数城市地区对开放空间的竞争非常激烈。但是，迄今为止，只有很少的水广场实现了，至少一项实施由于缺乏公众的接受而受到阻碍。在这项研究中，使用半结构化访谈来调查当地居民如何看待在科隆市建造水广场的计划。确定了对公众接受至关重要的因素。事实证明，对于洪水泛滥的经验，对计划中的建筑的了解以及对收益的认识对于接受而言非常重要，而社会和个人规范则没有那么重要。确定的因素导致找到建议，以促进公众接受创新的气候适应措施，例如水广场。
