Experimental study on local scour characteristics around an upstream inclined pile under combined wave and current action

Shui kexue jinzhan, 2022
In the context of wave-current, the characteristics of vortex structure and wave propagation around the upstream inclined pile differ significantly than around the vertical pile, which affects the local scour process of the pile foundation.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Does an Armor Layer Control Clear-Water Scour at Cylindrical Bridge Piers? A Comprehensive Experimental Assessment under Steady and Unsteady Flow Conditions

Journal of Hydrology and Hydromechanics
Local scour at bridge piers is a critical phenomenon jeopardizing structural integrity worldwide. This study presents a comprehensive physical modelling investigation into the evolution of local scour in the presence of a protective armor layer ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

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).

Clear-Water Experimental Scour Depths At Abutments

, 2018
Abstract—Laboratory experiments on local scour process at wing wall bridge abutments were conducted for different hydraulic conditions and compared with measurements on local scour depths around vertical wall abutments, under the same flow and sediment transport conditions.

Arthroscopic Repair of Radial Meniscal Tear Using Fibrin Clot Augmentation and “Hashtag” Style Inside‐Out Technique

Arthroscopy Techniques, EarlyView.
Abstract Significant meniscal injuries lead to pain and possible early osteoarthritis development. Fibrin clot augmentation represents an effective, cost‐efficient method for improving healing rates in poorly vascularized meniscal tears. This arthroscopic technique shows fibrin clot augmentation combined with horizontal and vertical mattress sutures in

Scour depth analysis beneath a submerged pipeline featuring a protective blade configuration

Results in Engineering
The primary objective of the current research extends beyond the examination of the impact of the protective blade on the geometric features, namely length (L) and depth (H), of the scour hole formed beneath the cylindrical submerged pipeline.

Local Scour at Complex Bridge Piers in Close Proximity under Clear-Water and Live-Bed Flow Regime

, 2019
In this study, we investigated the characteristics of scour at complex bridge piers in close proximity. The experiments were performed under both clear-water and live-bed flow regimes. We compare our results with those for a single complex pier. Further,
