Effect of ice cover roughness on local scour around bridge piers [PDF]

open access: yesScientific Reports
In cold-region rivers, the formation of ice cover during winter markedly modifies the hydraulic conditions, leading to enhanced local scour around in-stream infrastructures such as bridge piers. To analyze the flow characteristics and maximum local scour

Characteristics and mechanism of local scour reduction around spur dike using the collar in clear water [PDF]

open access: yesScientific Reports
To reduce the local scour around the spur dike, the U-shaped collar is proposed in this study. The influence of the collar's length, width, and porosity on the local scour reduction in clear water is studied by model tests and numerical simulations ...

Effect of Porosity on Local Scour Around Circular Array of Cylinders in Steady Currents

open access: yesShanghai Jiaotong Daxue xuebao, 2022
The local scour around a circular array of cylindrical piles through physical model was studied under the live-bed condition, concerning the effect of porosity of the structure on the local scour development.

Local Scour Mechanism of Offshore Wind Power Pile Foundation Based on CFD-DEM

open access: yesJournal of Marine Science and Engineering, 2022
The local scour around offshore pile foundations often seriously affects the normal operation of offshore wind power. The most widely used numerical simulation method in the study of local scour is the Euler two-fluid model (TFM).

Experimental study on local scour characteristics around an upstream inclined pile under combined wave and current action

open access: yesShui kexue jinzhan, 2022
In the context of wave-current, the characteristics of vortex structure and wave propagation around the upstream inclined pile differ significantly than around the vertical pile, which affects the local scour process of the pile foundation.

Large-scale experimental study on scour around offshore wind monopiles under irregular waves

open access: yesWater Science and Engineering, 2022
The Keulegan-Carpenter (KC) number is the main dimensionless parameter that affects the local scour of offshore wind power monopile foundations. This study conducted large-scale (1:13) physical model tests to study the local scour shape, equilibrium ...

Experimental study on local scour depth around pile groups

open access: yesEnergy Reports, 2022
An accurate prediction of local scour depth at piles is essential for bridge safety. In order to obtain the prediction formula of local scour around pile groups, a series of local scour experiments of pile groups were carried out.

Checking the Accuracy of Selected Formulae for both Clear Water and Live Bed Bridge Scour

open access: yesJournal of Engineering, 2023
Due to severe scouring, many bridges failed worldwide. Therefore, the safety of the existing bridge (after contrition) mainly depends on the continuous monitoring of local scour at the substructure.

On Local Scouring at Single Piers

open access: yesScientific Research Communications, 2021
The paper mostly summarizes disperse contributions of the authors published during the last fifteen years on the scour depth at single piers. These contributions rely on unique experiments in the sense that they are systematically longer than most of those found in the literature.
