Dynamics of a macrotidal estuary along 400 years based on historical maps and remote sensing: Araguari river, Amazon coast, Brazil

Revista Brasileira de Geomorfologia
Estuaries are environments subject to rapid morphological changes driven by variations in hydromorphological and climatic patterns. On the Amazon coast, these transformations have also been intensified by anthropogenic processes.

Impact of a large cylindrical roughness on tidal bore propagation [PDF]

, 2016
A tidal bore is a hydrodynamic shock, surging upstream in some shallow-water bays and estuaries during the flood tide under large tidal range. This study investigates experimentally the propagation of tidal bores over a large cylindrical roughness ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Listening to young children with disabilities: Experiences of quality in mainstream primary education

British Educational Research Journal, EarlyView.
Abstract All children should have access to quality education through a child‐centred pedagogy. An inclusive, child‐centred pedagogy uses a strength‐based view of children that recognises each child as unique and competent, providing children with multiple opportunities to explore and learn at their own pace.

Coupling between free-surface fluctuations, velocity fluctuations and turbulent Reynolds stresses during the upstream propagation of positive surges, bores and compression waves [PDF]

, 2016
In open channel, canals and rivers, a rapid increase in flow depth will induce a positive surge, also called bore or compression wave. The positive surge is a translating hydraulic jump.

A numerical study of tidal bores

Journal of Physics: Conference Series, 2019
Abstract A tidal bore is a natural phenomenon forming a positive surge upstream and it has a remarkable effect on estuary zones and river ecologies. The tidal bore formation controlled by channel properties, tidal characteristics, and river discharge remains a research challenge.

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 ...

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

Biological 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

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 ...

Shaping research in marine functional connectivity for integrated and effective marine science and management

Biological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...
