The effect of hydrostatic water level on the local scour downstream of plunging aerated jets [PDF]
Scientific ReportsThis paper reports an experimental study on the effect of hydrostatic water level on local scour downstream of plunge aerated jets. To examine the shape of the scour for non-cohesive bed material, different flow and air rates, and different aeration ...

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 ...

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

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.
