This paper reports on people's preparedness, perception and behaviour of flood risk as well as their trust and attitude towards public authorities in the flood context. Two areas were studied: Catcliffe, situated near Sheffield in the United Kingdom, which was severely flooded in 2007, and Passau in Bavaria, Germany, which was hit by an extreme flood in 2013. We conducted a survey in both study areas and collected data on risk perception, people's perceptions of their own preparedness, their use of information, trust in the authorities and evacuation behaviour. We found that although there were few significant differences between the two case studies, risk perception and risk preparedness was significantly higher in Catcliffe than in Passau and during the flood emergency people in Catcliffe see themselves acting more self-protectively (78%) than in Passau (42%). In both places, people who had direct experience of floods had a higher level of risk perception and preparedness compared to those with no previous experience. In both Catcliffe and Passau, trust in government was fairly low. Nevertheless, when people were asked the hypothetical question how they would react to a public evacuation order, almost 70% in Catcliffe and 80% of respondents in Passau would take immediate action to evacuate. Interestingly, the answer was similar when we asked the conflicting question whether the respondents would follow a public evacuation order although their family recommended not doing so.

本文报道了人们对洪水风险的防范，感知和行为，以及他们在洪水环境中对公共机构的信任和态度。研究了两个区域：位于英国谢菲尔德附近的卡特克利夫（Catcliffe），在2007年遭受严重洪灾；在德国巴伐利亚州的帕绍（Passau），在2013年遭受特大洪灾。我们在两个研究区域进行了调查，并收集了数据在风险感知，人们对自己的准备，信息使用，对当局的信任以及疏散行为方面的感知。我们发现，尽管两个案例研究之间几乎没有显着差异，卡特克利夫（Catcliffe）的风险感知和风险防范能力明显高于帕绍（Passau），在洪灾期间，卡特克利夫（Catcliffe）的人们发现自己的自我保护作用（78％）比帕绍（42％）高。在这两个地方，与没有洪水经验的人相比，直接经历洪水的人对风险的了解和准备水平更高。在卡特克利夫（Catcliffe）和帕绍（Passau），对政府的信任度都很低。但是，当人们被问到假设的问题时，他们将如何对公共疏散命令作出反应，卡特克利夫（Catcliffe）中将近70％的人和帕绍（Passau）中的80％的被调查者将立即采取行动撤离。有趣的是，当我们问这个有冲突的问题时，尽管他们的家人建议不要这样做，但回答者是否会遵循公共疏散命令，答案也差不多。
