Abstract
<p> This study describes an efficient ultra-high-resolution topographic measurement method to obtain hydraulic experimental data that should serve as a benchmark for the numerical fluid dynamics analysis of local scouring. In this study, small-scale model experiments were conducted to measure a scour hole's topography around a monopile of an offshore wind turbine foundation in combined waves and current, a current-alone, and a waves-alone. Using two types of synchronized laser displacements mounted on a self-propelled cart, we could quickly measure the scour holes with the ultra-high resolution with a grid spacing of less than 1/20 of the diameter of the monopile.</p>
