现在人们普遍认识到，多学科利益相关者之间的良好沟通是有效的洪水风险管理的核心。地理信息系统的最新发展、从遥感数据源获得的精确数字地形模型的增加以及图形计算机界面的改进，使利益攸关方很容易获得洪水淹没计算机模型的结果。因此，这些模型的预测现在被常规地用作工程师和洪水风险管理其他利益相关者之间的沟通手段。本文提供了一个审查的建模方法最适合洪水风险沟通。这些模型是一维模型，适用于在集水区或次集水区规模模拟洪水风险，并适用于传达战略洪水管理决策的影响;二维模型可在一系列规模上应用，但目前正定期应用于相对较小的规模，小于10平方公里，在这些规模上，它们有可能为灾害管理决策提供信息和传达。这种模型的作用，在建模者和非建模者之间的沟通，提供了一种手段，立即可视化的“未来”的讨论和说明应用到两个案例研究。
It is now widely recognised that good communication between multi-disciplinary stakeholders is central to effective flood risk management. Recent developments in Geographical Information Systems, increased availability of accurate digital terrain models from remotely sensed data sources and improved graphical computer interfaces have made the outputs from computer models of flood inundation easily accessible to the stakeholder community. As a consequence, predictions from such models are now being used routinely as a means of communication between engineers and other stakeholders in flood risk management. This paper provides a review of the modelling methods most appropriate for flood risk communication. These are one-dimensional models which are suitable for simulating flood risk at a catchment or sub-catchment scale and appropriate for communicating the impact of strategic flood management decisions and two-dimensional models which can be applied across a range of scales but, are now being regularly applied at the relatively small scale, less than 10 km2, where they have the potential to inform and communicate disaster management decisions. The role of such models in communicating between modellers and non-modellers by providing a means for immediate visualisation of “the future” is discussed and illustrated by application to two case studies.
