Numerical simulation of foundation scour for offshore wind turbines with large-diameter suction buckets

Shuili Shuiyun Gongcheng Xuebao
In order to investigate the scour crater morphology and maximum scour crater depth of a large-diameter suction bucket foundation under different working conditions with wave-current coupling effects, and to compare and analyze them with typical working ...

Equilibrium scour pattern around tandem piers at an intermediate below-critical inflow velocity

Journal of Hydrology and Hydromechanics
Scouring around bridge piers is one of the major reasons for bridge failure. A total of 20 experiments of scour around tandem piers were conducted in an open channel, at a subcritical inflow velocity (U/Uc=0.67) by placing an equal or smaller diameter ...

Artificial Neural Network Model for Predicting Local Equilibrium Scour Depth at Pile Groups in Steady Currents

Journal of Marine Science and Engineering
Piles are common support elements for marine and coastal structures. The scour around pile foundations caused by currents is a major threat to the stability and safety of these structures. The empirical equations commonly used for estimating the equilibrium scour depth around pile groups are limited in their predicative capability, especially when the ...

A Model sor Equilibrium Contraction Scour Depth at Bridges on Catchment Scale

Lokal erosion vid broar till följd av kontraktion uppstår när flödestvärsnittet minskar på grund av brokonstruktionen. I denna studie utvecklades en modell för att förutsäga jämviktsdjupet av kontraktionserosion vid en bro med hjälp av lättillgängliga data.

Effect of relative sediment size on clear-water equilibrium scour depth at single cylindrical piers

, 2011
Experiments on local scouring around cylindrical piers were performed in steady clear-water conditions to investigate the effect of sediment size, D50, on equilibrium scour depth, dse. Thirteen experiments, run for 7 to 13 days, were carried out. The dependence of the normalized equilibrium scour depth, dse/Dp, on the relative sediment size, Dp/D50 ...
