Numerical Investigation of Local Scour Around Bridge Pile-Group Foundations Under Steady Flows

Infrastructures
Local scour around pile-group foundations is a predominant cause of hydraulic instability in bridge engineering. This study employs a fully coupled three-dimensional computational fluid dynamics model to investigate local scour around a 2 × 2 inline pile

Local scour of composite cylindrical wind turbine foundation on fine sand seabed under combined waves and current

Energy Informatics
The composite cylindrical wind turbine foundation is characterized by its large-diameter cylindrical base, which offers superior anti-overturning capability, and it is widely used in the soft soil seabed of Jiangsu, China.

Long-term scouring effects on the lateral loading behaviour of monopiles using field monitoring data and finite element modelling

Applied Ocean Research
Scour of the seabed induced by currents and waves poses a critical threat to the serviceability and lifespan of offshore wind turbines. Despite its significance, the mechanisms and temporal evolution of offshore scour remain insufficiently understood ...

Experimental Scours by Impinging Twin-Propeller Jets at Quay Wall

Journal of Marine Science and Engineering, 2020
Experiments were conducted to investigate the seabed scour holes due to the interaction between the twin-propeller jet and quay wall. Vertical quay wall was modelled by using a polyvinyl chloride (PVC) plastic plate in a water tank.

Influence of scour depth and flow velocity field on large-diameter pier group pile foundations

Frontiers in Marine Science
Sea-crossing bridges face critical challenges due to scour, which can destabilize foundations. This study investigates the scour characteristics of the large-diameter main pier of the Haiwen Bridge, with a pile diameter of 4.3 meters. Seabed changes were

Internal parasites and association with diarrhoea in sheep at an abattoir in Western Australia [PDF]

, 2005
Diarrhoea (scouring) is an important issue for the sheep meat industry. Scouring is a major risk factor for fleece soiling and consequential carcase contamination with microbes that cause meat spoilage and potential dangers for humans (2).

Modeling of local scour depth downstream hydraulic structures in trapezoidal channel using GEP and ANNs

Ain Shams Engineering Journal, 2013
Local scour downstream stilling basins is so complex that it makes it difficult to establish a general empirical model to provide accurate estimation for scour depth. Lack estimation of local scour can endanger to stability of hydraulic structure and can
