The paper presents an experimental study of local scour around truncated vertical piles subject to oscillatory flow. The experiments were conducted with six height-to-diameter ratios (h/D =0.25-3.5) and three KC numbers (33, 52 and 80). The development of scour depth around the pile was reported. It was found that the effect of h/D on the scour depth reduces with increasing KC, and h/D does not affect the finial scour depth anymore when h/D ≥ 2.5. For the three KC numbers tested here, the scour time scale reduces with the increase of h/D when h/D ≤ 0.5. The finial scour profiles were scanned through a three-dimensional scanner. The slope angle of the scour hole was extracted from the three-dimensional scan.
