Modeling analysis of tidal bore formation in convergent estuaries [PDF]

European Journal of Mechanics - B/Fluids, 2019
Despite the recognized impact of tidal bores on estuarine ecosystems, the large scale mechanism of bore formation in convergent alluvial estuaries is still under investigation. So far, field data exist only for a small number of estuaries, while numerical simulations employ the shallow water equations mainly focusing on the small-scale and local ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

A global satellite survey of density plumes at river mouths and at other environments: Plume configurations, external controls, and implications for deep-water sedimentation

Petroleum Exploration and Development, 2018
The U. S. National Aeronautics and Space Administration (NASA) has archived thousands of satellite images of density plumes in its online publishing outlet called ‘Earth Observatory’ since 1999.

Hydrodynamic and sedimentary processes of tidal bores: Arcins Channel, Garonne River in August-September-October 2015 [PDF]

, 2016
A tidal bore is a compressive wave of tidal origin, propagating upstream as the tidal flow turns to rising. It might be observed when a macro-tidal flood flow enters a funnel shaped river mouth with shallow waters.

Physical Modelling of Breaking Tidal Bores: Comparison with Prototype Data [PDF]

, 2015
A tidal bore is a hydraulic jump in translation, propagating upstream as the tide turns to rising and the flood flow advances in a funnel-shaped river mouth under spring tide conditions. This study focused on the unsteady turbulence induced by a breaking

Turbulence and turbulent flux events in tidal bores: case study of the undular tidal bore of the Garonne River [PDF]

Environmental Fluid Mechanics, 2017
The tidal bore of the Garonne River (France) was investigated on 29 August, 31 August and 27 October 2015, during which instantaneous velocity measurements were performed continuously at high-frequency (200 Hz). The tidal bore occurrence had a marked effect on the flow field and turbulent Reynolds stress data, indicating large shear stresses, together ...

Transcranial Doppler ultrasound validation of BOLD-fMRI cerebral blood flow relationship. [PDF]

Magn Reson Med
Abstract Purpose A precise understanding of the interplay between cerebral blood flow (CBF) and blood oxygen level‐dependent (BOLD) fMRI signals is essential for advancing cerebrovascular research. Although calibrated BOLD approaches often rely on arterial spin labelling (ASL) to estimate CBF, alternative validation using transcranial Doppler ...

Tidal bore of the Sélune River, Baie du Mont Saint Michel (France) [PDF]

, 2009
On 7 April 2004, the tidal range in the Baie du Mont Saint Michel was nearly 14 m. A tidal bore was seen for nearly 2 hours in the Baie and later in the Sée and Sélune Rivers.
