Exponential expression for time evolution in local scour

Journal of Hydraulic Research/De Recherches Hydrauliques, 2004
Some properties of the exponential expression for time evolution in local scour processes are presented in this work. Using the exponential expression, it is shown that it may not be possible to find an equilibrium scour depth in the case of “short” tests, in spite of a good fitting of the data. The results are supported with real data.

Processes and evolution of scour around a monopile induced by tidal currents

Coastal Engineering, 2018
Abstract Despite offshore wind farms being mostly situated in tidally dominated waters, only limited research on the effects of tidal flow on the scour process around offshore foundation structures has been carried out so far. To further improve the prediction of scour around those structures, systematic laboratory tests were conducted in a closed ...

Temporal Evolution of Scour at Submerged Circular Cylinders

Journal of Marine Science and Application, 2021
Temporal evolutions of scour at submerged circular cylinders were investigated. Flow visualization was carried out around the cylinders over plane, under developed and equilibrium scour holes. Video analysis technique was used to formulate the equations for determining the diameter of the horseshoe vortex around the submerged cylinders, which is also ...

Equilibrium morphology and scour evolution at blunt nosed chevrons

River Research and Applications, 2021
AbstractBlunt nosed chevrons are low‐head river restoration structures commonly used in large rivers to enhance the navigation and aquatic habitat. These structures usually create scour regions in their vicinity, which provides habitat for various aquatic organisms. Furthermore, the scour pools represent suitable locations for fish nursery.

Time evolution of scouring downstream of bed sills

Journal of Hydraulic Research, 2003
Results of laboratory experiments conducted on time evolution of the scouring phenomenon at bed sills are presented. Starting from previous findings on long-term depth and length of the local scour hole downstream of bed sills, 12 long-duration tests were designed and performed in the Sloping Sediment Duct at HR Wallingford Ltd, using uniform sand.
