A buoyant plume adjacent to a headland—Observations of the Elwha River plume
Continental Shelf Research, 2011Small rivers commonly discharge into coastal settings with topographic complexities – such as headlands and islands – but these settings are underrepresented in river plume studies compared to more simplified, straight coasts. The Elwha River provides a unique opportunity to study the effects of coastal topography on a buoyant plume, because it ...

Coastal river plumes: Collisions and coalescence
Progress in Oceanography, 2017Abstract Plumes of buoyant river water spread in the ocean from river mouths, and these plumes influence water quality, sediment dispersal, primary productivity, and circulation along the world’s coasts. Most investigations of river plumes have focused on large rivers in a coastal region, for which the physical spreading of the plume is assumed to be

The Level and Fate of Metals in the Danube River Plume
Estuarine, Coastal and Shelf Science, 2002Abstract Trace metal concentrations were measured in the Danube River at different locations along the three main branches of the delta. Results from a systematic delta survey in 1997 and those from the 1995 cruise indicate that the ranges of the total dissolved concentrations in the river end-member are: A1=211–445 nM, Cd=224–302 pM, Co=266–390 pM ...

Variability of river plume in the Gulf of Tonkin
2021<p>The quality of estuarine, coastal and marine environment in the Gulf of Tonkin, in the South China Sea, is an essential issue to the ecosystems&#8217; health and to the living conditions and economy of the Viet Nam population.

On the energetics of river plume entrainment
Geophysical & Astrophysical Fluid Dynamics, 1979Abstract There are fundamental differences between the mechanics of entrainment in river plumes and two-layer channel flow. Entrainment of seawater to a river plume is seen to occur predominantly in a frontal region. A simple theory for the energetics of frontal entrainment is applied to river discharge in a wide fjord with a seaward narrows.

Journal of Physical Oceanography, 1988
Abstract The development, maintenance, and dissipation of river-forced estuarine plumes with and without seaward sloping bottom are studied by use of a three-dimensional, primitive-equation model. Inside the estuary, discussion is focused on how the Coriolis force induces lateral asymmetries in the circulation.

Tidal influence on the Fraser River plume
2022The Fraser River plume in the Strait of Georgia, BC, is significantly influenced by the tide. Here we use 17 years of daily MODIS observations of suspended particulate matter to understand the tidal variability of the plume. Our results show a consistent negative correlation between the Fraser River plume area and the tidal elevation with a phase lag ...

Analysis of the Niagara River plume dynamics
Journal of Geophysical Research: Oceans, 1992The Niagara River discharges into Lake Ontario at a typical rate of 6500 m3/s, and is the lake's principal source of suspended and dissolved materials. The discharge plume is frequently warmer and thus more buoyant than the surrounding lake surface water.

Areas of the global major river plumes
Acta Oceanologica Sinica, 2013River plumes are the regions where the most intense river-sea-land interaction occurs, and they are characterized by complex material transport and biogeochemical processes. However, due to their highly dynamic nature, global river plume areas have not yet been determined for use in synthetic studies of global oceanography.

Mixing and Transport in Coastal River Plumes
Annual Review of Fluid Mechanics, 2015River plumes are generated by the flow of buoyant river water into the coastal ocean, where they significantly influence water properties and circulation. They comprise dynamically distinct regions spanning a large range of spatial and temporal scales, each contributing to the dilution and transport of freshwater as it is carried away from the source ...
