WAVE, WAVE RUN-UP AND OVERTOPPING MEASUREMENTS IN THE FIELD USING LASER SCANNERS

This paper presents five years (2019 – 2024) of wave, wave run-up and overtopping measurements using two laser scanners (LIDARs) in the Eems-Dollard estuary in the north of the Netherlands during severe winter storms. The paper focuses mainly on the lessons learned: the improvements that have been made to the measurement system and analysis techniques during these five years and the interpretation and validation of the measured data. To this end, the paper describes the measured storms, the data analysis and results, which are validated with data from a radar, step gauge, ADCP, overtopping tanks in the dike, video recordings, numerical wave models and wave run-up and overtopping equations.
