3D scour below pipelines under waves and combined waves and currents [PDF]
Coastal Engineering, 2014 This paper presents the results of an experimental investigation on three-dimensional local scour below a rigid pipeline subjected to wave only and combined wave and current conditions. The tests were conducted in a conventional wave flume. The major emphasis of the investigation was on the scour propagation speed (free span expansion rate) along the ...

Flow Structure in an Artificial Seagrass Meadow in Combined Wave-Current Conditions
Frontiers in Marine Science, 2022 Experiments were conducted in a laboratory flume using an artificial seagrass meadow, modeled after Zostera marina, to examine the impact of waves on the vertical structure of time-averaged current, Reynolds stress, and turbulent kinetic energy (TKE ...

Wave damping by seagrass meadows in combined wave‐current conditions
Limnology and Oceanography, 2022 AbstractLaboratory experiments using an artificial seagrass meadow modeled after Zostera marina measured the impact of following currents on meadow‐induced wave decay as a function of the imposed current velocity , wave velocity , and wave Cauchy number , which is the ratio of hydrodynamic drag force to restoring force due to blade stiffness. For small

Relationship between Three-Dimensional Radiation Stress and Vortex-Force Representations
Journal of Marine Science and Engineering, 2021 In numerical ocean models, the effect of waves on currents is usually expressed by either vortex-force or radiation stress representations. In this paper, the differences and similarities between those two representations are investigated in detail in ...

Shoaling Waves Interacting with an Orthogonal Current
Journal of Marine Science and Engineering, 2020 In the present work, an experimental investigation on the hydrodynamics of shoaling waves superposed on a steady orthogonal current is carried out. An experimental campaign in a wave tank has been performed, with waves and current interacting at a right ...

Wave Run-Ups and Overtopping Affected by Oblique Wave Approaches and Currents
Slovak Journal of Civil Engineering, 2022 To quantify the effect of a current on the height of a wave’s run-up and overtopping combined with an oblique wave approach, the “FlowDike” hydraulic research project was carried out. Tests were performed on two dike slopes of 1:3 and 1:6.

Onset of Motion of Sediment underneath Scour Protection around a Monopile
Journal of Marine Science and Engineering, 2018 The stability of scour protections is, potentially, an important issue during the design of fixed foundations for offshore wind turbines. One of the failure mechanisms observed at placed scour protection around offshore foundations is suction of sediment
