Others concentrated on the flow field around the cylinder, via experimental measurements (Dey and Raikar, 2007;Graf and Istiarto, 2002;Graf and Yulistiyanto, 1998;Unger and Hager, 2007) and numerical experiments (Gobert et al, 2010;Kirkil et al, 2008Kirkil et al, , 2009Rolound et al, 2005). Link et al (2008) and Diab et al (2010) presented detailed measurements of developing and equilibrium scour holes around cylinders in fine sand and gravel, respectively.…”
