[1] During the winters of 1998 and 1999, observations were made of the cascading of cold water from the nearshore, shallow "shelf'' zones and down the sloping sides of Lake Geneva. Cascading starts on the average 10 hours after the onset of surface cooling ...
Iron isotopes were used to investigate iron transformation processes during an in situ field experiment for removal of dissolved Fe from reduced groundwater. This experiment provided a unique setting for exploring Fe isotope fractionation in a natural syst ...
The gas push−pull test (GPPT) is a single-well gas-tracer method to quantify in situ rates of CH4 oxidation in soils. To improve the design and interpretation of GPPT field experiments, gas component transport during GPPTs was examined in abiotic porous me ...
Numerical simulations compared with field measurements are used to explain the effect of sea breezes on photochemical smog episodes in Athens during the Mediterranean Campaign of Photochemical Tracers on 12-14 September 1994. The numerical simulations, per ...
This thesis describes the development and selected applications of a global vegetation model, BIOME4. The model is applied to problems in high-latitude vegetation distribution and climate, trace gas production, and isotope biogeochemistry. It demonstrates ...
We present experimental results on the velocity statistics of a granular fluid with an effective stochastic thermostat, in a quasi-two-dimensional configuration. We find the base state, as measured by the single particle velocity distribution P(c) in the c ...
Observations made from vertical moorings of thermistors and current meters are used to analyze the relative contribution of the entrainment of overlying water and the cold plumes convecting from the surface to the cascade of dense shelf waters down the sid ...

The logarithmic layer of double-averaged (in time and space) streamwise velocity profiles obtained from field measurements made in the Swiss rivers, Venoge and Chamberonne is parameterized and discussed. Velocity measurements were made using a 3D Acoustic ...
The Arve River is the most important tributary of the Rhone River The Arve has a very high sediment transport capacity due to its steep slope in the Alpine Valley. These solid materials deposit in the Rhone River. Because of the high sedimentation rate in ...
Lake delta morphology is determined by fluvial input, waves, lake currents, lake-level fluctuations and lake-basin topography. The current-dominated Versoix delta (Petit-Lac of Lake Geneva, Switzerland), has been studied in order to determine the role of w ...
