Abstract
Oosterlo et al. (2019) developed a system using two terrestrial laser scanners, which can measure run-up heights, depths and velocities of waves on a dike in field situations. The system has now been placed next to two overtopping tanks on a dike in the Eems-Dollard estuary in the Netherlands to measure during actual severe winter storms. The goal of the present paper is to further validate this innovative system with data obtained during storm Ciara (10 - 12 February 2020), a severe winter storm with very oblique wave attack. Furthermore, the data gathered during storm Ciara will be compared to the current knowledge on wave overtopping, to possibly gain new insights in the influence of very oblique wave attack on wave overtopping.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/TwSwJuxb-Yo
Highlights
The goal of the paper is to further validate this innovative system for measuring wave run-up heights, depths and front velocities, and for determining the wave overtopping, (peak) wave period and angle of incidence during an actual severe winter storm with very oblique wave attack

The laser scanner system of Oosterlo et al (2019) has since been upgraded and has been placed next to two of the overtopping tanks on the dike in the Eems-Dollard estuary to measure during actual severe winter storms, see Figure 2
Summary
The goal of the paper is to further validate this innovative system for measuring wave run-up heights, depths and front velocities, and for determining the wave overtopping, (peak) wave period and angle of incidence during an actual severe winter storm with very oblique wave attack. These validation tests showed that the system can measure the run-up heights, depths and velocities of waves on a dike in field situations. The measurements started in 2018, measuring wind, water levels, waves and wave run-up and overtopping.
