Laboratory Study of Local Scour Around an Array of Pile Groups in Clear-Water Scour Conditions

Journal of Marine Science and Engineering
Current-induced local scour around pile groups weakens the capacity of structures. In this paper, experimental tests of local scour around an array of 5 × 5 pile groups were conducted in a steady current in a hydraulic flume.

Local Scour of Bridge Pier Sited on a Multi-Layered Sedimentary Bed in Rivers [PDF]

E3S Web of Conferences, 2020
The riverbeds or sea beds are usually composed of multi-layers of sediments. The scour around bridge piers sited on such beds is vital to the bridge safety, but is still very difficult to be predicated as its complicated interaction between the flow and ...

On local scouring downstream small water structures

PeerJ, 2020
Background In order to regulate water flow, hydraulic structures such as weirs or checks, frequently equipped with gates, are used. Water can flow below or over the gate or, simultaneously, over and below the gate.

Experimental and numerical investigation into the local scour of bridge cofferdam with anti-scour ribs

Advances in Bridge Engineering
Cofferdam is widely employed in the construction of underwater bridge foundations. Its crucial attribute lies in providing a dedicated platform for construction activities and enhancing the water resistance dimensions in structural design, consequently ...

Observations of River Topography and Flow Around Bridges [PDF]

, 2009
This investigation was motivated by the amount of river, estuarine, and coastal infrastructure that is susceptible to extreme wave and flooding events. The high velocities and resulting shear stresses associated with high flow velocities are capable of ...

Three‐Dimensional Hierarchical Nanowire‐Networks with Deep‐Focus Tolerance and Adhesion Robustness for Harsh‐Environment SERS Sensing

Advanced Functional Materials, EarlyView.
A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Studying the effect of partial blockage on multi-vents bridge pier scour experimentally and numerically

Ain Shams Engineering Journal, 2018
The local scour depth at bridge supports due to partial blockage on front of multi-vents bridge pier is studied experimentally and numerically. The existence of blockage such as debris and industrial wastes, leads to increase the local scour depth around

Analisis Susunan Tirai Optimal Sebagai Proteksi Pada Pilar Jembatan Dari Gerusan Lokal [PDF]

, 2008
Local scour frequently occurs in the downstream of energy muffler or around the bridge pillars. The bridge pillar function decreases due to the scour of soil material around it.

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

Advanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...
