本文介绍了VOWS（海堤波浪剧烈越浪）项目下的新研究。允许越浪量的既定指南是基于平均流量值。在涉及对行人/车辆的危害的情况下，显然，容许的漫顶水平更适合基于单个漫顶事件的量。此外，所造成的危险不仅是越浪量的函数，而且也是射流速度和轨迹的函数。存在预测最大单个越浪量的方法。本文提出了新的数据和第一个预测工具的越浪“抛出速度”，第一个数据从一个装置设计直接测量的轨迹越浪射流。
This paper describes new research under the VOWS (Violent Overtopping of Waves at Seawalls) project. Established guidance on admissible overtopping volumes is based upon values of mean discharge. In cases where hazard to pedestrians / vehicles are concerned, it is clear that an admissible level of overtopping would be more appropriately based upon the volume of an individual overtopping event. Further, the hazard presented is not only a function of the volume of that overtopping wave, but also of the speed and trajectory of the jet. Methods exist to predict maximum individual overtopping volumes. This paper presents new data and a first predictive tool for overtopping “throw velocities”, and first data from a device designed to measure directly the trajectories of overtopping jets.
