Influence of scour depth and type on p–y curves for monopiles in sand under monotonic lateral loading in a geotechnical centrifuge

open access: yesOcean Engineering, 2020
The influence of scour on the lateral response of monopile foundations for offshore wind turbines is investigated in this paper. Application of lateral load-displacement (p-y) curves to predict the lateral pile behaviour is subject to uncertainty as many

Quantification of Modelling Uncertainties in Bridge Scour Risk Assessment under Multiple Flood Events

open access: yesGeosciences, 2019
Local scour is a dynamic process evolving during the lifetime of bridges as a result of the changes in hydrologic and hydraulic conditions. Current approaches for scour risk assessment are generally based on the evaluation of the equilibrium scour depth ...

Analysis of Lateral Dynamic Response of Caisson Foundation in Layered Clayey Soils considering Scour-Hole Dimensions

open access: yesShock and Vibration, 2020
As a cross-sea or river deep-water foundation, it is clear that the caisson foundation will be subjected to significant lateral dynamic loads due to winds or waves and suffer from scouring under its long-term effect.

Morphology Evolution of Three-Dimensional Scours Under Submerged Jets

open access: yesFrontiers in Earth Science, 2022
Through physical model tests, the three-dimensional morphological features and their scale changes with time were measured and comparatively analyzed during the scouring of a homogeneous granular bed surface using submerged oblique jets.

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 ...

Three-dimensional scour simulations with a two-phase flow model

open access: yesAdvances in Water Resources, 2020
In this contribution, a three-dimensional sediment scour model based on the two-phase flow Eulerian-Eulerian solver, sedFoam, is developed within the framework of the open source platform OpenFOAM. The adoption of the Eulerian approach for both fluid and

Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour

open access: yesApplied Sciences, 2020
The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

Machine Learning Solutions for Bridge Scour Forecast Based on Monitoring Data

open access: yesTransportation Research Record, 2021
Bridge scour is a challenge throughout the U.S.A. and other countries. Despite the scale of the issue, there is still a substantial lack of robust methods for scour prediction to support reliable, risk-based management and decision making. Throughout the

Modal properties variation and collapse assessment of masonry arch bridges under scour action

open access: yesEngineering structures, 2019
This paper investigates the problem of flood-induced scour on masonry arch bridges through the analysis of a real case study, Rubbianello Bridge. This is a multi-span masonry arch bridge located in Central Italy, which suffered the collapse of two of the
