Conventional methods to measure wave height, e.g. resitance type of wave probes, are considered an intrusive measuring method limited to 1 dimension only.
With several linescans retrieved with a laser scanner a temporally and spatially high resolution measurement of the wave is obtained. Allowing for detailed study of the wave shape, wave breaking or run- up characteristics...
Still this is a relativeley new approach and research concerning the influencing parameters on the scanning, accuracy and validation of the measurements as well as optimum set- up is under progress.
Hence in a first step a complete list of parameters influencing the scanning of water waves is necessary. Since the scanning of water is a relativley new approach no such list is available yet.
Based on experiments conducted in the Deltares Deltagoot, TU Delft Flume and Deltares Scheldegoot, test data from several scan experiments
is analyzed and several, the quality of the scan influencing parameters (incident angle, wavelength, measurement principle, water turbidity, wave characteristics, SNR, ...), are researched.
Finally an optimum scanner is chosen and an optimum set- up for the new Deltares Deltaflume facility given.
