Turbulent advances of a breaking bore: preliminary physical experiments [PDF]

open access: yes, 2015
In an estuary, a tidal bore may be generated at the leading edge of the flood tidal wave during the early flood tide under spring tide conditions into a narrow funnelled channel.

‘I, Me, Myself’: Selfhood and Melancholy in the Journals of Gertrude Savile (1697–1758)

open access: yesJournal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines the journals of Gertrude Savile from 1727 in light of recent scholarship on early modern and eighteenth‐century melancholy. The concept had myriad associations with medicine, physiology, the imagination, and feeling, but questions remain about how melancholy during this period was considered by those outside the narrow ...

Breaking tidal bore: comparison between field data and laboratory experiments [PDF]

open access: yes, 2013
A tidal bore is a surge of waters propagating upstream as the tidal flow turns to rising and the flood tide rushes into a funnel shaped river mouth with shallow waters. The present study focused on the unsteady turbulence induced by a breaking tidal bore

Positive Surge Propagation in Sloping Channels [PDF]

open access: yes, 2017
A simplified model for the upstream propagation of a positive surge in a sloping, rectangular channel is presented. The model is based on the assumptions of a flat water surface and negligible energy dissipation downstream of the surge, which is ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

open access: yesBoreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

A Numerical Study of Tidal Bore and Dam-break Flows Using CIP Method [PDF]

open access: yes, 2008
A numerical model was developed based upon the C-CUP method equipped with LES model and a re-initialisation method. The model was validated and applied to the laminar dam-break flow, the turbulent dam-break flow and the tidal bore flow with a weak ...

Digital Publishing, Ethics and Hydraulic Engineering: The Elusive or "Boring" Bore? [PDF]

open access: yes, 2008
From the "boring boar" of Astérix and Obélix, to the tidal bore of the Indus River that wiped out the fleet of Alexander the Great, the English word "bore" has been used for a broad range of meanings.

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Life‐stage and environmental influences on the recruitment of African freshwater eels into the uThukela River, South Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anguillid eel recruitment into east‐flowing rivers along the east coast of Africa is poorly understood. The few harvest records of anguillid eels from South Africa have highlighted anthropogenically derived environmental stressors as risks for further decline.
