海浪漫过海防设施对人员和基础设施构成危险。海平面上升和有限的资源意味着需要准确的预测工具来提供具有成本效益的海岸线管理计划。现场数据的缺乏意味着用于洪水预报和海岸方案设计的数值工具主要基于理想化水槽研究的数据，并且由此产生的漫顶预测对于复杂结构和某些环境条件可能具有数量级的不确定性。此外，这类研究通常只提供关于漫顶水总量的数据，而没有关于水流速度的数据。在这里，我们介绍了WireWall，一个基于电容的传感器阵列，可以逐波测量漫顶水的速度和体积。我们描述的成功验证WireWall对传统的水槽方法和目前的结果，从第一次试验部署在英国的海堤。WireWall的结果进行了比较，数值预测的基础上EurOtop的指导。WireWall技术提供了一种可靠获取开发弹性海岸保护计划所需数据的方法。
Wave overtopping of sea defences poses a hazard to people and infrastructure. Rising sea levels and limited resources mean accurate prediction tools are needed to deliver cost-effective shoreline management plans. A dearth of in-situ data means that the numerical tools used for flood forecasting and coastal scheme design are based largely on data from idealised flume studies, and the resulting overtopping predictions may have orders of magnitude uncertainty for complicated structures and some environmental conditions. Furthermore, such studies usually only provide data on the total volume of overtopping water, and no data on the speed of the water. Here we present WireWall, an array of capacitance-based sensors which measure the speed and volume of overtopping water on a wave-by-wave basis. We describe the successful validation of WireWall against traditional flume methods and present results from the first trial deployments at a sea wall in the UK. WireWall results are also compared with numerical predictions based on EurOtop guidance. WireWall technology offers an approach for reliable acquisition of the data needed to develop resilient coastal protections schemes.
