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 ...

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.

Re-parameterization of equilibrium scour depths and time scales for monopiles
Coastal Engineering, 2023 Empirical formulations for the engineering prediction of equilibrium scour depths, as well as time scales (for both scour and backfilling), are re-visited for monopiles. Following prior work, it is argued on physical grounds that dimensionless time scales ought to scale proportionally to the Shields parameter raised to the −3/2 power, based on scaling ...

Scour Characteristics and Equilibrium Scour Depth Prediction around a Submarine Piggyback Pipeline [PDF]
Journal of Marine Science and Engineering, 2022 Local scour around a submarine piggyback pipeline in combined waves and current is investigated experimentally. Based on the experimental results, the scour evolution and scour morphology are firstly analyzed. Then, a comparison with the equilibrium scour depth Seq between the present experimental data and predicted results is conducted.
