N2 - Hydraulic model tests were carried out in a closed-circuit flume in order to investigate the progression of scour at a monopile under tidal currents in clear-water conditions. The tidal currents were based on field measurements and were simulated by a quasi-continuous approach. In addition, as a result of scour measurements at multiple positions around the pile and a high temporal resolution novel insights on the intrinsic progression of sediment displacement and time scale of the scour process around a monopile under tidal currents are presented. Based on infilling and sediment displacement, the time development of the maximum scour depth under tidal flow is unsteady and characterized by periods of stagnating and decreasing scour depth. This leads to a significant slower progression of the scour depth compared to unidirectional currents with a flow velocity based on the maximum peak velocity of the tidal signal. Furthermore, large variations of scour depth at the upstream and downstream side of the pile result in altering positions of maximum scour depth over time.
