Effect of inflow channel aspect ratio on the plunging dynamics of an unconfined hyperpycnal plume over a sloping bed Open
Hyperpycnal (denser) river inflows into lakes bring sediments, nutrients, oxygen and contaminants, which are crucial for the water quality. Due to the higher densities of hyperpycnal inflows, they abruptly descend toward the lake bottom up…

Hydro-sedimentary processes of a lofting turbidity current revealed by gridded ADCP measurements in the field Open
Hyperpycnal (negatively buoyant) river inflows into lakes or reservoirs plunge upon entry, generating gravity-driven underflows near the bed. When the density excess of these underflows is primarily due to high sediment concentrations, the…

Characteristics of turbidity current events in Lake Geneva, Switzerland Open
Turbidity currents represent a distinctive type of subaqueous density currents, characterized by a density excess that is due to the sediment load. Turbidity currents are important in lakes, reservoirs and oceans and have implications on h…

Quantifying Turbulent Mixing in Plunging River Inflows: Insights from Field Measurements in Lake Geneva Open
Hyperpycnal river inflows discharging into lakes or reservoirs will plunge and trigger gravity-driven underflows near the bed. Such underflows are called turbidity currents if the density excess is mainly caused by a high sediment concentr…

Hydro‐Sedimentary Processes of a Plunging Hyperpycnal River Plume Revealed by Synchronized Remote Imagery and Gridded Current Measurements Open
The present knowledge of plunging hyperpycnal river plumes is mainly based on two‐dimensional (confined) laboratory experiments. Several hypotheses on three‐dimensional (unconfined) flow processes have been made, but not tested in situ. In…

Evidence and possible causes of velocity pulsing in a turbidity current in Lake Geneva Open
<p>Negatively buoyant riverine inflows plunge when entering lakes or reservoirs and form gravity-driven currents near the bed. When a high sediment load causes the density excess, such currents are called turbidity currents. They can…

From inflow to interflow, through plunging and lofting: uncovering the dominant flow processes of a sediment-rich negatively buoyant river inflow into a stratified lake Open
<p>Lake and reservoir water quality is impacted greatly by the input of momentum, heat, oxygen, sediment, nutrients and contaminants delivered to them by riverine inflows. When such an inflow is negatively buoyant, it will plunge upo…

Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva Open
<p>River inflows have a major influence on lake and reservoir water quality through their input of momentum, heat, oxygen, sediment, nutrients and contaminants. The fate of these components is controlled by the hydrodynamic processes…

Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva Open
Turbidity currents emanating from the Rhône River into Lake Geneva were first inferred by François-Alphonse Forel in the nineteenth century. This site remains attractive for several reasons. (1) Permanent measuring stations on the Rhône an…
