Sediment transfer in the Rhône River Basin, Switzerland: the role of localized severe Alpine storm events on triggering turbidity currents in Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert, François Mettra

In Lake Geneva, a deep peri-Alpine lake in Switzerland, the sublacustrine Rhône River delta presents a deep canyon, the Rhône Canyon. Previous studies and recent observations show that low-velocity underflows and high-velocity turbidity currents pass frequ ...

Spatial and temporal changes of primary production in a deep peri-alpine lake

Alfred Johny Wüest, Damien Bouffard, Tiit Kutser

Lake productivity is fundamental to biogeochemical budgets as well as estimating ecological state and predicting future development. Combining modelling with Earth Observation data facilitates a new perspective for studying lake primary production. In this ...

Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert

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 and Lake Geneva pro ...

The role of mass-transport deposits and turbidites in shaping modern lacustrine deepwater channels

Nicolas Le Dantec

Subaquatic canyons are an important pathway for sediment transport into oceanic and lacustrine basins. Understanding the mechanisms governing their geomorphological evolution is a key to predict the sediment distribution patterns through these sediment con ...

Atmospheric new particle formation as a source of CCN in the eastern Mediterranean marine boundary layer

Athanasios Nenes

While cloud condensation nuclei (CCN) production associated with atmospheric new particle formation (NPF) is thought to be frequent throughout the continental boundary layers, few studies on this phenomenon in marine air exist. Here, based on simultaneous ...

Peracetic Acid Oxidation of Saline Waters in the Absence and Presence of H2O2: Secondary Oxidant and Disinfection Byproduct Formation

Urs von Gunten

Peracetic acid (PAA) is a disinfectant considered for use in ballast water treatment, but its chemical behavior in such systems (i.e., saline waters) is largely unknown. In this study, the reactivity of PAA with halide ions (chloride and bromide) to form s ...

HYMEX-SOPI The Field Campaign Dedicated to Heavy Precipitation and Flash Flooding in the Northwestern Mediterranean

Alexis Berne

The Mediterranean region is frequently affected by heavy precipitation events associated with flash floods, landslides, and mudslides that cause hundreds of millions of euros in damages per year and, often, casualties. A major field campaign was devoted to ...

Precipitation, soil moisture and runoff variability in a small river catchment (Ardeche, France) during HyMeX Special Observation Period 1

Jacopo Grazioli, Timothy Hugh Raupach

Flash flooding is a potentially destructive natural hazard known to occur in the Cevennes-Vivarais region in southern France. HyMeX (Hydrological Cycle in the Mediterranean Experiment) is an international program focused on understanding the hydrological c ...

Evaporation from a shallow water table: Diurnal dynamics of water and heat at the surface of drying sand

Marc Parlange, Ivan Lunati, Chad Higgins, Scott W. Tyler

Accurate estimates of water losses by evaporation from shallow water tables are important for hydrological, agricultural, and climatic purposes. An experiment was conducted in a weighing lysimeter to characterize the diurnal dynamics of evaporation under n ...

Lessons from a lost technology: The secrets of Roman concrete

Ruben Anton Snellings

Roman concrete was used as building material during Roman Imperial times for a great number of famous constructions with different functions. Well-known examples are aqueducts, for example the Pont du Gard in France and the Aqua Alexandrina in Rome, and nu ...
