Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Experimental investigations of local scour around piles in a single-column and three-columns with multiple rows in steady current

Applied Ocean Research
Local scour around pile groups is a common phenomenon in fluvial and coastal engineering, leading to a reduction in the bearing capacity of pile foundations frequently.

Study of the time-dependent clear water scour around circular bridge piers

Journal of Hydrology and Hydromechanics, 2017
The local scour around bridge piers influences their stabilities and plays a key role in the bridge failures. The estimation of the maximum possible scour depth around bridge piers is an important step in the design of the bridge pier foundations.

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.

Influence Mechanisms of Spatial Optimization of the “Terraced Fields‐Gully Land Reclamation Project (GLRP)” Cascades on Erosion‐Transportation Processes in Watershed in the Loess Hilly‐Gully Region of China

Land Degradation &Development, EarlyView.
ABSTRACT Terraced fields and the Gully Land Reclamation Project (GLRP) are important soil and water conservation measures, widely constructed in China's Loess Plateau and other ecologically fragile areas in the world. However, under large‐scale governance scenarios, the impacts of the “terraced fields‐GLRP” cascade system on water and sediment ...

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, EarlyView.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...

Local scour at group of bridge piers founded in gravel bed in staggered arrangement

Results in Engineering
Local scour around bridge piers is the common cause of undermining of bridge foundation. Many researchers have studied local scour around bridge pier in finer sediment bed.

Scour depth beneath a pipeline undergoing forced vibration

Theoretical and Applied Mechanics Letters, 2015
This paper studies the coupling effect of the pipeline vibration on the seabed scour. A vertical two-dimensional model is applied to numerically investigate the local scour below a vibrating pipeline with different amplitudes and periods. Using the scour

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Experimental study on local scour around the submerged vertical circular cylinder under solitary wave action

Shui kexue jinzhan, 2019
Solitary waves can cause intense sediment movement in the coastal area,resulting in local scour around the offshore structures that use submerged pile foundations,and seriously affecting the stability of offshore structures.
