Sediment Transport Circulation Pattern through Mesotidal Channels System
TL;DR: In this article, the authors focus on the bed sediment transport pointing to the pathway migration rather than the sediment transport rate itself, and estimate the transport of non-cohesive sediments, mobilized by the channel floor.

Multibeam investigation of an artificial reef settlement in the Adriatic sea (Italy) 33 years after its deployment
TL;DR: In this article, the EM3002 multibeam echosounder was used to investigate the first scientifically planned artificial reef in Italy deployed during 1974-75 during which a considerable scouring around the structures and some vertical/horizontal movements of the single units have occurred.

Causes and Treatment Measures of Submarine Pipeline Free-Spanning
TL;DR: A review of the causes and treatment measures for the free span of submarine pipeline is provided in this paper, which provides a convenient resource for understanding the causes of submarine free-spanning pipelines and choosing suitable treatment measures.

Exploring 3D Wave-Induced Scouring Patterns around Subsea Pipelines with Artificial Intelligence Techniques
TL;DR: In this article, Artificial Intelligent (AI) techniques are employed to present new equations for predicting three dimensional current-and wave-induced scour rates around subsea pipelines, among which are the Shields' parameter, the Keulegan-Carpenter number, relative embedment depth, and wave/current angle of attach.

Experimental investigation of the equilibrium scour depth below submerged pipes both in live-bed and clear-water regimes under the wave effect
TL;DR: In this article, the equilibrium scour depth below submerged pipes due to regular waves was investigated experimentally during the experiments various pipe diameters, bed material grain sizes and wave characteristics were used The experiments were performed both in live-bed and clear-water regime conditions.

Erosion of mud/sand mixtures
Helen Mitchener,Hilde Torfs +1 more
TL;DR: In this article, the authors investigated the relationship between the erosional properties of combined mud and sand sediments, and found that adding sand to mud, or vice versa, increases the erosion resistance and reduces the erosion rates when the critical shear stress for erosion is exceeded.

Cohesive Material Erosion by Unidirectional Current
TL;DR: In this paper, the initiation of motion of consolidated cohesive sediments under a unidirectional flow of clear water was studied in a flume-tunnel capable of providing a bed shear stress up to 26 Pa and a velocity of 3.5 m/s, 3 mm above the bed.

Seepage force on a pipeline buried in a poroelastic seabed under wave loadings
TL;DR: The water wave induced seepage force on a pipeline buried in the seabed is investigated in this paper, where the pipeline is assumed to be rigid and not supported by any anchoring force.

Wave-induced uplift force on a submarine pipeline buried in a compressible seabed
TL;DR: In this paper, a finite element simulation of the wave-induced hydrodynamic uplift force acting on a submarine pipeline buried in sandy seabed sediments subject to continuous loading of sinusoidal surface waves is presented.
