Abstract
Submerged breakwaters are an important measure to protect the shore from the
destructive effects that high water waves might have. In a first step towards
understanding the action and transformation of these waves, a wave tank
experiment, containing a model of such structure was set up. The facility and the
measuring technique are described in which two-dimensional waves could be
studied by laser Doppler anemometry (LDA). Two-dimensional LDA
measurements were performed, yielding information on the complex interaction
between the waves and the structure. Phase average properties of the mean
velocity field were calculated as well as phase average r.m.s. values of the
velocity fluctuations, through the measured values. The results are presented at
33 x-locations. The data provide an insight into th
