The role of mass-transport deposits and turbidites in shaping modern lacustrine deepwater channels
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 ...
Elsevier2016Sediment dynamics in the subaquatic channel of the Rhone delta (Lake Geneva, France/Switzerland)
With its smaller size, well-known boundary conditions, and the availability of detailed bathymetric data, Lake Geneva's subaquatic canyon in the Rhone Delta is an excellent analogue to understand sedimentary processes in deep-water submarine channels. A mu ...
Springer Verlag2014Morphological analysis of the upper reaches of the Kukuy Canyon derived from shallow bathymetry
Yosef Akhtman, Nicolas Le Dantec
We present preliminary results on the morphology of the upper reaches of the Kukuy Canyon and Selenga shelf in front of Proval Bay (Lake Baikal), derived from newly acquired, high-resolution bathymetry. Numerous and varied erosional and transport features ...
2014Current variability in a wide and open lacustrine embayment in Lake Geneva (Switzerland)
David Andrew Barry, Alfred Johny Wüest, Ulrich Lemmin, Roham Bakhtyar, Amir Mehdi Razmi, Nicolas Le Dantec
Field measurements and numerical simulations were used to determine the effects of dominant meteorological conditions on the hydrodynamics of a wide (aspect ratio ~2), relatively deep (seasonally stratified) and open lake embayment (Vidy Bay, Lake Geneva). ...
Elsevier Sci Ltd2013Gyre formation within embayments of a large lake (Lake Geneva, Switzerland)
David Andrew Barry, Alfred Johny Wüest, Ulrich Lemmin, Damien Bouffard, Amir Mehdi Razmi, Nicolas Le Dantec
Numerical simulations were carried out to examine gyre formation within open, wide lacustrine embayments. The present study was motivated by observed differences in gyre formation within two open and wide embayments (located at Vidy and Morges in Lake Gene ...
2013Morphology of pillow-hollow and quilted-cover bedforms in Lake Geneva, Switzerland
David Andrew Barry, Ulrich Lemmin, Yosef Akhtman, Nicolas Le Dantec, Dragos Constantin
Extensive areas of the bottom of Lake Geneva are covered with bedforms that have been referred to as pillow-hollows and quilted-cover pattern by prior observers, as well as with sediment waves and trenches. These structures are decimeter to meter scale. A ...
Flanders Marine Institute (VLIZ), Royal Belgian Institute of Natural Sciences and SHOM2013Deployment of a dynamic penetrometer from manned submersibles for fine-scale geomorphology studies
David Andrew Barry, Ulrich Lemmin, Nicolas Le Dantec
Dynamic penetrometers reveal information about seafloor strength, stratification, stability, and sediment remobilization. However, positioning is often limited to a range of meters making it difficult to target small-scale geomorphologic features. Deployme ...
Association for the Sciences of Limnology and Oceanography2013Triggering mechanisms and geomorphological implications of debris flows in subaquatic canyons: The Rhone delta (Lake Geneva, Switzerland, France)
Subaquatic canyons in deltas are major pathways for the transport of particles from rivers / the upper delta slops to the deep basins. They represent active environments with frequent deltaic failures and massmovements potentially bearing hazard-related (t ...
2012Sedimentary processes and triggering mechanisms of debris flows in subaquatic canyons in Rhone delta (Lake Geneva, Switzerland, France)
Subaquatic canyons in deltas are major pathways for the transport of particles from land to the deep basins. They represent active environments with frequent deltaic failures and mass-movement deposits potentially leading to hazardous (tsunami waves) and e ...
2012Sedimentological processes in the Rhone Delta subaquatic canyons (France-Switzerland)
Deltas are very sensitive environments and highly vulnerable to variations in water discharge and the amount of suspended sediment load provided by the delta-forming currents. Human activities in the watershed, such as building of dams and irrigation ditch ...
