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…
