The effective communication of flood risk offers the opportunity to ensure communities can adapt and respond appropriately to changing local conditions. At a time of diminishing resources, such local responses, which can empower communities and make them more resilient to uncertain future flood events, are vital. The most general and accessible type of flood communication are flood risk visualisations, i.e. pre-prepared emergency flood maps. However, evidence suggests there is much we can do to improve their ability to communicate the complexities of flood risk to a range of stakeholders. This paper considers the development of flood risk visualisation approaches in the UK, presenting findings from a series of targeted workshops over twelve months, where the needs and criteria of stakeholder groups for effective flood risk visualisation were assessed via co-creative processes. Key stakeholders included local authorities, emergency responders, vulnerable homeowners, Environment Agency, business owners and, crucially, communities. These users need certain requirements to be considered in order for future flood risk visualisation to be effective, in particular simplicity, a central hub of information, different visuals available for the same data sets/problems, different maps available for different users, consistent terminology and integrated community knowledge (e.g. local flood groups/help).

有效的洪水风险沟通为确保社区能够适应变化的当地条件并做出适当反应提供了机会。在资源日益减少的时刻，这种能够增强社区能力并使其对未来不确定的洪灾事件更具抵抗力的当地应对措施至关重要。洪水通信中最通用，最易访问的类型是洪水风险可视化，即预先准备的紧急洪水地图。但是，有证据表明，我们可以采取许多措施来提高他们向一系列利益相关者传达洪水风险的复杂性的能力。本文考虑了英国洪水风险可视化方法的发展，并介绍了过去十二个月中一系列针对性研讨会的发现，通过共同创作过程评估了利益相关者团体对有效洪水风险可视化的需求和标准。主要利益相关者包括地方当局，紧急响应者，脆弱的房主，环境署，企业主，以及至关重要的社区。这些用户需要考虑某些要求，以使未来的洪水风险可视化变得有效，尤其是简单性，中央信息枢纽，可用于相同数据集/问题的不同视觉效果，可用于不同用户的不同地图，一致的术语以及综合社区知识（例如当地的洪水小组/帮助）。
