This paper presents an experimental study, which concerns about scour around the pile supported wharf under progressive waves and pressure variations on the pile around the scour hole. In this context, rigid bed and actual scour bed experiments were conducted. The cylinder was flush mounted to the flume wall and flume base, water seepage was prevented in these regions. Pressure measurements were obtained by five pressure transducers, which were flush mounted on the surface of the cylinder above the flume bottom. The pressure measurements were made also for actual scour bed at the same low Keulegan-Carpenter number (KC 1). In order to determine the scour and deposition regions around the cylinder, the sediment pit located on the flume bottom was scanned with a laser scanner before and after the experiments and the final bed topography was visualized and contour maps were sketched. The results are indicated scour hole near the cylinder is more than 4 times than the wall free pile cases.
