Heavy precipitation events are expected to increase in frequency and intensity in many parts of Europe as a result of climate change. These events can affect regions located far from rivers that have never been affected before. As warning times are short, there are hardly any effective emergency measures to mitigate the severe damage caused by pluvial floods. Therefore, long‐term mitigation measures are necessary for sustainable urban flood management. However, people first need to realise their personal risk in order to become active and take private precautionary measures. To get a better understanding of the processes underlying public risk perception of pluvial floods, a questionnaire‐based telephone survey was conducted analysing two case studies in western Germany. Key findings reveal that risk perceptions need to be distinguished between personal and global perception. Personal risk perception was low among the participants, while their global risk perception was far higher. The determinants of global and personal risk perception on pluvial flooding were identified. The study also showed that mitigation behaviour is influenced by personal risk perception, knowledge, education, and housing conditions. These determinants should receive attention when future risk communication and flood management strategies are developed.

公共风险感知对有效管理城市小雨洪水的重要性：来自德国的案例研究

由于气候变化，预计欧洲许多地区的强降水事件的频率和强度都会增加。这些事件可能会影响远离从未受到过影响的河流的地区。由于预警时间很短，因此几乎没有有效的紧急措施来减轻小雨洪水造成的严重破坏。因此，长期缓解措施对于可持续的城市洪水管理是必要的。但是，人们首先需要意识到自己的个人风险，才能变得活跃并采取私人预防措施。为了更好地理解对小水灾的公共风险感知的潜在过程，进行了一项基于问卷的电话调查，分析了德国西部的两个案例研究。主要发现表明，需要将风险感知与个人感知和全球感知区分开。参与者的个人风险感知度较低，而其总体风险感知度较高。确定了对小水灾的全球和个人风险感知的决定因素。研究还表明，缓解行为受个人风险感知，知识，教育和居住条件的影响。在制定未来的风险沟通和洪水管理策略时，这些决定因素应引起注意。研究还表明，缓解行为受个人风险感知，知识，教育和居住条件的影响。在制定未来的风险沟通和洪水管理策略时，这些决定因素应引起注意。研究还表明，缓解行为受个人风险感知，知识，教育和居住条件的影响。在制定未来的风险沟通和洪水管理策略时，这些决定因素应引起注意。
