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 ...

Local Scour Mechanism of Offshore Wind Power Pile Foundation Based on CFD-DEM
Journal of Marine Science and Engineering, 2022 The local scour around offshore pile foundations often seriously affects the normal operation of offshore wind power. The most widely used numerical simulation method in the study of local scour is the Euler two-fluid model (TFM).

Characteristics and mechanism of local scour reduction around spur dike using the collar in clear water. [PDF]
Sci RepTo reduce the local scour around the spur dike, the U-shaped collar is proposed in this study. The influence of the collar's length, width, and porosity on the local scour reduction in clear water is studied by model tests and numerical simulations ...

Tidal Bore Scour around a Spur Dike
Journal of Marine Science and Engineering, 2022 Tidal bores are a natural phenomenon with high flow velocity and destructive potential. A spur dike is a widely used river regulation and embankment protection structure that minimizes erosion, promotes deposition, and protects riverbanks.

New flow relaxation mechanism explains scour fields at the end of submarine channels [PDF]
Nature Communications, 2019 AbstractParticle-laden gravity flows, called turbidity currents, flow through river-like channels across the ocean floor. These submarine channels funnel sediment, nutrients, pollutants and organic carbon into ocean basins and can extend for over 1000’s of kilometers.

Analysis on slope stability by anchorage based on soil creep with flood effect [PDF]
HeliyonIn order to analyze the adverse effect of flood affection on slope stability, the analytical expressions of buoyancy force and capillary force, hydrodynamic pressure and impact force, and scour erosion were proposed based on the aging characteristics of ...

Physical Mechanism for Seabed Scouring around a Breakwater—A Case Study in Mailiao Port
Journal of Marine Science and Engineering, 2022 According to a field survey in 2012, the bathymetry near Mailiao Port, located in central Taiwan’s west coast, has a scouring hole that extends approximately 500 m × 100 m with a maximum scour depth of 26 m (eroded from its design depth −22 m to −48 m ...
