Study on the Mechanism of Local Scour Around Bridge Piers

open access: yesJournal of Marine Science and Engineering
Local scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Experimental reintroduction of woody debris on the Williams River, NSW: geomorphic and ecological responses [PDF]

open access: yes, 2004
A total of 436 logs were used to create 20 engineered log jams (ELJs) in a 1.1 km reach of the Williams River, NSW, Australia, a gravel-bed river that has been desnagged and had most of its riparian vegetation removed over the last 200 years.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

open access: yesJournal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Estimation of Scour Depth at Bridge Piers by Using FASTER Model and Experimental Formulas [PDF]

open access: yesمهندسی منابع آب, 2017
Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors.

Bridge pier flow interaction and its effect on the process of scouring [PDF]

open access: yes, 2015
University of Technology Sydney. Faculty of Engineering and Information Technology.Previous investigations indicate that scour around bridge piers is a contributor in the failure of waterway bridges. Hence, it is essential to determine the accurate scour

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

open access: yesDroplet, 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.

Interplay Between Green Investment and Market Price Premia in Global Shipping

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT Existing research emphasises that the driver of green investment is its future profitability. This paper shows that other investors' decisions also influence green investment. We take the example of scrubber installation in shipping, which is optional by regulation but has an established market for trading its underlying asset.
