文摘The local scour around a large -scale vertical circular cylinder due tocombined wave-current action was experimentally and numerically studied in the present paper.Experiments were carried out to research the affect of the wave height, current velocity and thediameter of the cylinder on the scour process. The topography near the cylinder in various casesduring scour was measured. The cylinder diameter affects the distribution of scour and depositionarea. The maximum scour depth increases evidently when the current velocity increases. The maximumscour depth does not increase after the wave height retains a certain value. A numerical model usinga finite element method for simulating the scour process was established. And the numerical resultsagree well with the measured, data. The numerical model is more applicable in the case oflarge-scale cylinders.
