A moored profiling platform to study turbulent mixing in density currents in a large lake
David Andrew Barry, Ulrich Lemmin, François Mettra, Rafael Sebastian Reiss, Valentin Kindschi, Benjamin Daniel Graf
During calm cooling periods, differential cooling can induce winter cascading which is an important process for littoral-pelagic exchange and deep water renewal in large, deep lakes (Fer et al., 2001; Peeters et al., 2003). Generated in the shallow near-sh ...
2023One possible future for Grande Dixence
Sarah Catherine Amélie Planchamp
IPCC reports stop their predictions in 2100. An abrupt line in eighty years from now. Yet infrastructure, including buildings last for longer than that: what we build now is the heritage we will have to deal with when we reach that line. As such, engineers ...
2023Modeling Compact Intracloud Discharge (CID) as a Streamer Burst
Narrow Bipolar Pulses are generated by bursts of electrical activity in the cloud and these are referred to as Compact Intracloud Discharges (CID) or Narrow Bipolar Events in the current literature. These discharges usually occur in isolation without much ...
2020An Assessment of the State-of-the-Art from the 2019 ARO Dynamic Stall Workshop
Karen Ann J Mulleners, Fatma Ayancik Cinoglu
Dynamic stall has been a limiting factor in design and operation on rotating systems within the rotorcraft, propulsion, and sustainable energy disciplines for more than forty years, impacting operational performance and component fatigue. In the last decad ...
2020Tracking Lagrangian transport in Lake Geneva: A 3D numerical modeling investigation
David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus
Lake Geneva, the largest freshwater lake in Western Europe, is subject to important environmental pressures from its densely populated shores and watershed. To maintain and improve water quality in this lake, as well as in other enclosed or semi‐enclosed b ...
2019Experimental results of gravity currents travelling over a fissured bed
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Gravity currents are geophysical flows having large impact on human life and on the environment. The need to prevent and mitigate their negative consequences justifies the multitude of studies carried out to understand their physics. However little has bee ...
2019Mass loss of density currents travelling over pourous bed
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Polluted liquids leaking from their storages over the surrounding gravel beds or oil spilling into aquifers, are examples of gravity currents moving over a porous terrain. Density-driven flows provoked by saline or temperature differences or turbidity curr ...
2019Geomorphic work by gravity currents with varying initial conditions
Gravity currents are density-driven flows that are able to transport high amounts of sediment and are responsible of great geomorphic changes. Moreover they can have severe repercussions on the environment since they are conveyors of substances, e.g. pollu ...
EPFL2018Structure of a dense release produced by varying initial conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan
Buoyancy driven flows such as gravity currents, present in nature and human made applications, are conveyors of particles or dissolved substances for long distances with clear implications for the environment. This transport depends on the triggering condi ...
2018Large Eddy Simulations of sediment entrainment induced by a lock-exchange gravity current
Carmelo Juez Jiménez, Jessica Zordan, Foteini Kyrousi, Alessandro Leonardi
Large Eddy simulations of lock-exchange gravity currents propagating over a mobile reach are presented. The numerical setting allows to investigate the sediment pick up induced by the currents and to study the underlying mechanisms leading to sediment entr ...
