Evolution of local scour downstream of Type A PK weir in non-cohesive sediments
Journal of Hydrology and Hydromechanics, 2022 A large-scale piano key weir laboratory study was conducted to investigate the evolution of the scour process occurring in the downstream basin for two non-cohesive granular bed materials, including the analysis of scour-hole geometry and patterns at ...

The Science behind Scour at Bridge Foundations: A Review
Water, 2020 Foundation scour is among the main causes of bridge collapse worldwide, resulting in significant direct and indirect losses. A vast amount of research has been carried out during the last decades on the physics and modelling of this phenomenon.

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

Proceedings of the 39th IAHR World Congress, 2022 Monitoring system is essential for improving the understanding of scour processes next to structures built in the riverine environment. State-of-the-art review shows a lack of field scour measurements due to expensive specialized equipment, time-consuming surveys, and difficulties in data acquirement during floods.

Visualization Tests on Variation of Scour Front under a Pipeline in Steady Currents
Journal of Marine Science and Engineering, 2019 The intersection of the span shoulder and the scour hole under a pipeline, also called the scour front, can affect the scour hole extension rate and the bearing capacity of the span shoulder, which is associated with pipeline spanning and failure ...
