Abstract

A number of different methods for the 3D measurement of the water surface in previous termwave fieldsnext term have been proposed in the literature, based mostly on refraction, photogrammetry and/or reflected light intensity. Although these methods can map the distorted water surface, they appear to be difficult in practical applications in hydraulic engineering laboratories. A novel previous termwave mappingnext term technique using previous termparticle image velocimetrynext term to measure surface flow velocities, and linear previous termwavenext term theory to determine previous termwavenext term heights from the measured velocities, has been developed and validated for regular previous termwaves.next term The method allows for the previous termmappingnext term even of complex previous termwave fieldsnext term with simple means and appears robust enough for application in the laboratory.
