Temporal variation of clear-water scour at compound Abutments

open access: yesAin Shams Engineering Journal, 2016
Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

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

open access: yesThe 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 ...

Impacts of coastal vegetation on tsunami-induced overtopping scour behind embankments and local scour around buildings

open access: yesApplied Ocean Research
This study experimentally investigates the role of coastal vegetation in adjusting tsunami-induced overtopping scour behind embankments and local scour around buildings.

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Hazards due to large wood accumulations: Local scour and backwater rise

open access: yesE3S Web of Conferences, 2018
Large wood (LW) in rivers increases the flow variability and provides habitats for various species. During flood events, transported logs can accumulate at river infrastructures and increase the flood hazard.

Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Investigating the effect of curved shape of bridge abutment provided with collar on local scour, experimentally and numerically

open access: yesAin Shams Engineering Journal, 2015
Scour around bridge supports such as abutments can result in structural collapse and loss of life and property, so there is a need to control and minimize the local scour depth.

Regulation Through Revelation: The Effect of Pollution Monitoring on Labour Demand

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates how manufacturing firms respond to a real‐time pollution monitoring programme, with a focus on the implication for employment. Contrary to the conventional expectation that environmental regulations negatively impact business, the findings reveal that enhanced pollution monitoring has a significant and robust positive ...
