Visualization of the Onset of Scour under a Pipeline in Waves [PDF]
Applied Sciences, 2020 This paper visualizes the onset of scour under a pipeline in regular waves and studies the mechanism in this process. After the test started, the sand particles near the downstream mudline began to oscillate periodically, probably due to the distribution

Scour patterns below pipelines and scour hole expansion rate [PDF]
Scour and Erosion, 2016 This paper presents the results of an experimental study on the onset of scour and the propagation of scour hole on the cross-section of a partially buried pipeline under a unidirectional current with uniform sediment. A specially designed device including a transparent pipeline with a mini underwater camera installed inside it is utilized to observe ...
