Numerical investigation of wave-induced local scour around a submarine pipeline
, 2014 A two-dimensional numerical model is developed in this work to predict the local scour around subsea pipelines induced by the orbital fluid motion due to free-surface water waves. Instead of being simplified as an oscillatory flow, the motion of the wave

On local scouring downstream small water structures
PeerJ, 2020 Background In order to regulate water flow, hydraulic structures such as weirs or checks, frequently equipped with gates, are used. Water can flow below or over the gate or, simultaneously, over and below the gate.

Local Scour at Bridge Abutments
Journal of King Abdulaziz University-Engineering Sciences, 1998 This paper presents the results of an experilnental investigation of local scour at bridge abutment models of three common shapes placed in laboratory flume with uniform sand with d)l) =0.775 mm. The 1l1uximum scour depths and extent of scour were determined corresponding to clear water conditions.

Study on the Mechanism of Local Scour Around Bridge Piers
Journal of Marine Science and EngineeringLocal scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour
Applied Sciences, 2020 The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...
