Coupling Effects of Flow Regimes and Pulsation Frequencies on the Spatio-Temporal Evolution of Monopile Scour Through Experimental Study

Journal of Marine Science and Engineering
Scour around monopile foundations is a pivotal challenge in nearshore engineering, as it undermines sediment support and threatens structural stability.

Temporal Evolution of Plunge Pool Scour

, 2008
The temporal development of plunge pool scour was investigated using a novel experimental approach. Longitudinal profiles along the scour hole were recorded with an optical method to allow its definition at any time, from the initiation of scour to ...

Numerical Investigation of Coupled Vortex-Induced Vibration and Scour of Subsea Pipelines under Ocean Currents

Journal of Marine Science and Engineering
Sediment transport beneath subsea pipelines is essentially a highly complex multiphase flow problem, involving strong coupling between hydrodynamics, structural response, and sediment transfer.

Hydro-morphological investigations on local scour around inclined piles under wave conditions

Water Science
Scouring is a problem that should be considered while designing bridges; scour around inclined piles in the presence of waves has rarely been researched.

Scour Near Offshore Structures—Part 2: Practical Scour Model

Journal of Marine Science and Engineering
Scour near various offshore structures has been studied by performing numerical model runs with the modified (Fortran) SEDTUBE model, as a follow-up of an earlier paper on scour near marine offshore structures. A fairly simple 1D numerical model (SEDTUBE

Scour at coastal structures [PDF]

, 2006
The subject of scour (and siltation) at coastal structures continues to receive much interest in the consulting and research fields. Coastal structures can be categorised as having four functions, either (1) to provide permanent protection against ...

Temporal Pier Scour Evolution under Stepped Hydrographs

, 2011
The present study was aimed at measuring the scour hole profile at bridge piers under clear water scour. Scour tests were performed under both steady state flow and under stepped hydrographs.

Experimental Study of the Scour Regimes Downstream of an Apron for Intermediate Tailwater Depth Conditions

Journal of Applied Fluid Mechanics, 2014
The local scour of a non-cohesive bed due to a 2-D submerged horizontal jet is investigated experimentally in presence of a protection apron. Previous researches conducted without protection apron demonstrate that, when the tailwater depth is either deep
