영문 초록

Scour around subsea windfarm foundation is a threat to its stability and the cable’s functioning. Underwater scour is affected by waves, currents, bed material and water depth. Prediction of scour depth can be classified into empirical methods, numerical methods, and laboratory experiments. Recently time-evolution of scour depth has been described by a time-advancing computation with empirical formula. RANS-type modelling has been refined to simulate horse-shoe scour by including the jet effect. Recent scour protection methods include two-step protection: wait until scour hole develops and then put rock armour layer at the time.
