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
