Scour evolution around a vibrating monopile in cohesive beds

, 2017
With the advent of Offshore Wind Farms (OWF), energy security of many countries has the potential to progress towards self-sustainability. Early stages of offshore turbine installation took place in nearby post transgressional shallow sands. These locations were preferentially developed given their relative ease of installation, maintenance and ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Scour evolution for steady and unsteady flow conditions downstream of Type A piano key weirs

Journal of Hydrology and Hydromechanics
For the first time a comprehensive analysis for steady and unsteady flow conditions was performed of timedependent scour processes in non-cohesive sediment downstream of a Type A piano key weir.

Separation and Valorization of Chlorine From Tail Gas Streams

Angewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Equilibrium scour morphology downstream of rock sills under unsteady flow conditions

E3S Web of Conferences, 2018
The present study aims to analyze the equilibrium scour morphology occurring downstream of rock-made sills with different shapes, under different inflow conditions. Namely, experimental tests were conducted under both steady and unsteady flow conditions.

Multi-approach analysis of maximum riverbed scour depth above subway tunnel

Water Science and Engineering, 2010
When subway tunnels are routed underneath rivers, riverbed scour may expose the structure, with potentially severe consequences. Thus, it is important to identify the maximum scour depth to ensure that the designed buried depth is adequate.

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Experimental Comparison of Sacrificial Piles and Submerged Vanes as Scour Countermeasures around Bridge Pier [PDF]

Journal of Rehabilitation in Civil Engineering, 2019
An experimental study has been conducted on the effectiveness of two types of flow-altering countermeasures placed around a cylindrical pier under clear water condition, which consists of sacrificial piles and submerged vanes.

Heuristic assessment of bridge scour sensitivity using differential evolution: case study for linking floodplain encroachment and bridge scour [PDF]

Environmental Systems Research, 2016
Stakeholders are often required to make judgments and decisions about the tradeoffs between multiple competing objectives inherent in any engineering design. Design optimization can provide decision support for such situations, but often prescribes that only a single design solution be selected for a given set of preferences.

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 ...
