The Carboniferous Southern Pennine Basin, UK [PDF]

open access: yes, 2014
Many of the Carboniferous outcrops located in the Derbyshire region of the Peak District National Park, UK, have provided sites for both significant and pioneering research relating to the clastic sedimentology of marine palaeoenvironments, particularly ...

Local Scour around Side-by-Side Double Piers in Channel Bends under Ice-Covered Conditions—An Experimental Study

open access: yesWater, 2023
The pier scour process is normally intensified in the presence of an ice cover, which poses risks to the longevity and safety of bridges. In the present study, the impact of the densimetric Froude number, locations, and pier spacing of side-by-side piers

3D Modeling and Mechanism Analysis of Breaking Wave-Induced Seabed Scour around Monopile

open access: yes, 2020
Breaking wave-induced scour is recognized as one of the major causes of coastal erosion and offshore structure failure, which involves in the full 3D water-air-sand interaction, raising a great challenge for the numerical simulation. To better understand

Local scour around complex pier groups and combined piles at semi-integral bridge

open access: yesJournal of Hydrology and Hydromechanics, 2014
This research presents an experimental study on the scouring mechanism at semi-integral bridge piers. Based on laboratory experiments, this study focuses on the relationship between scour depth in complex pier groups and combined piles bridge and various

Experimental study on scour at unpaved road shoulder [PDF]

open access: yesMATEC Web of Conferences
Scour is often found along the shoulder of the road, especially the shoulder without pavement in suburban and rural areas. This can reduce the function of the road shoulder and increase the risk of traffic accidents.

Estimation of the Maximum Scour Depth at Bridge Pier under Effects of Debris Accumulations using NF-GMDH Model and Evolutionary Algorithms [PDF]

open access: yesمحیط زیست و مهندسی آب, 2019
Rivers accumulate huge amounts of floating debris including the trunk, branches and leaves during the floods, leading to increase the depth of local scour around bridge piers.

Flow hydrodynamics across open channel flows with riparian zones: implications for riverbank stability [PDF]

open access: yes, 2017
Riverbank vegetation is of high importance both for preserving the form (morphology) and function (ecology) of natural river systems. Revegetation of riverbanks is commonly used as a means of stream rehabilitation and management of bank instability and ...

Developing empirical formulae for scour depth in front of Inclined bridge piers

open access: yesGrađevinar, 2023
Because of the complex flow mechanism around inclined bridge piers, previous studies have proposed different empirical correlations to predict the scouring depth in front of piers, which include regression analysis developed from laboratory measurements.

The influence of collar parameters on local scour mechanism around the circular pier at the bend

open access: yesApplied Water Science
Analysis of bridge failures due to scouring has been extensively studied by different researchers in recent years and as a result various methods of controlling local scour cavity have been given. Since most of the research in this field has been done on
