Bridge Scour Analysis for Rocks: Classification, Method Selection, and Practical Case Studies
HydrologyDespite the availability of several scour calculation methods, bridge scour analysis for scour susceptible rocks is much less understood than its counterpart for sands, because scour calculation equations were traditionally obtained using flume tests ...

Morphology Evolution of Three-Dimensional Scours Under Submerged Jets
Frontiers in Earth Science, 2022 Through physical model tests, the three-dimensional morphological features and their scale changes with time were measured and comparatively analyzed during the scouring of a homogeneous granular bed surface using submerged oblique jets.

Scour‐control and scour‐resistant design for hydraulic structures [PDF]
Eos, Transactions American Geophysical Union, 1942 There now exists in theoretical analyses, in laboratory findings, and in conventional engineering‐design practice, a skeleton of facts on which a rational scour‐control procedure can be based. The writer has assembled these facts and stated them in as straightforward a manner as he believes, in consistent with current knowledge.

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 ...

Monopile response to scour and scour protection
, 2020 Scour of seabed sediments can occur around offshore structures, the resultant reduction in strength and stiffness of the structure’s foundations presents operational challenges for monopile-supported offshore wind turbine structures. Turbines are at risk of reduced operation or even premature decommissioning if scour causes the natural frequency of a ...

Scour near Offshore Monopiles, Jacket-Type and Caisson-Type Structures
Journal of Marine Science and EngineeringScour near various offshore structures (monopile, caisson foundation and jacket structure) was studied by performing laboratory flume tests and numerical solutions with a semi-empirical model (SEDSCOUR) and a sophisticated 2DV model (SUSTIM2DV).

Shui kexue jinzhan, 2019 The characteristics of local scour around large-diameter submerged cylinders are quite different from the non-submerged ones under combined wave and current conditions. Local scour model tests are carried out in a wave-current flume. A submerged cylinder
