Scour Characteristics and Equilibrium Scour Depth Prediction around Umbrella Suction Anchor Foundation under Random Waves [PDF]
Journal of Marine Science and Engineering, 2021 A series of numerical simulation were conducted to study the local scour around umbrella suction anchor foundation (USAF) under random waves. In this study, the validation was carried out firstly to verify the accuracy of the present model. Furthermore, the scour evolution and scour mechanism were analyzed respectively.

The equilibrium depth of wave scour around both slender and large piles
Ocean Engineering, 2021 Abstract The equilibrium stage of the scour caused by the wave effect around the marine piles was investigated experimentally for both slender and large piles. Unlike the experimental studies in the literature, some of the experiments were carried out under clear water scour condition, since the coarse bed material was used in the present study ...

An Examination of the Dependency between Maximum Equilibrium Local Scour Depth and the Grain Size/Structure Size Ratio [PDF]
Water (Switzerland), 2020 This paper begins by demonstrating how the Florida Department of Transportation (FDOT) local scour equations take the ratio between grain size and structure size into account when computing equilibrium local scour depth and contrasts this with the well-known Colorado State University (CSU) equation that does not take sediment information into account ...

Effect of Transversal Bed Slope on the Equilibrium Scour Depth at Bridge Piers
Journal of Hydraulic EngineeringThis study focused on the effect of the transversal bed slope on scouring at bridge piers. Twenty-four experiments were conducted, half of them being on a horizontal bed and the other half on inclined beds. Three inclination angles, three flow intensities, and three pier diameters were combined within the degrees of freedom of the available ...
