Lane’s Relation in Local Scour Investigations [PDF]

open access: yesIEEE Access, 2020
Alluvial river channels undergo transformations due to fluvial processes such as water flow which invokes soil particles movement. Mentioned processes are interrelated and can be described as a feedback relation which means that hydraulic and morphological features adjust to each other during the process of obtaining the dynamic balance between water ...

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.

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.

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.

Simplified analysis of dynamic response of pile-supported bridge under local scour and verification by centrifugal shaking tests

open access: yesYantu gongcheng xuebao, 2021
Scour causes the erosion of soil, changes the seismic response of site, and also influences the seismic properties of bridge. To investigate the dynamic behavior and damage potential of pile-supported bridges at local scour site, the effects of scour on ...

Experimental study on local scour around the pile on the sandy seabed under wave action

open access: yesShui kexue jinzhan, 2018
The local scour caused by a pile on a slope differs to that at the flat sand bed. A 1:16 slope with sediment median size of 0.32 mm was set up, and an experimental study of local scour around the pile under the action of regular wave was conducted. Under

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low‐resource settings: a prospective quality improvement study

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...
