Atmospheric boundary layers in complex terrain and over ice, snow and vegetated surfaces

Michael Lehning, Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Marc Diebold, Andreas Christen

Recent field campaigns held at the Val Ferret watershed in 2012 provided turbulent measurements in the atmospheric surface layer with and without snow cover. The turbulent kinetic energy (TKE) over the snow was reduced in comparison to the measurements obt ...

Impact of snow variability on the Swiss winter tourism sector: implications in an era of climate change

Camille Gonseth

With its numerous mountain regions and its well developed winter tourism infrastructures, Switzerland is a country whose tourism sector is known to be sensitive to snowpack variability. With climate change—which is predicted to have negative impacts on sno ...

Simulating melt crust and ice lens formation in a physically based snowpack model

Michael Lehning, Nander Wever, Charles Fierz

Water flow in a natural snow cover is generally a complex process because of the strongly stratified and changing structure of the snowpack. Important differences in, for example, density and grain size between layers cause sometimes very sharp transitions ...

A comparison between two statistical and a physically-based model in snow water equivalent mapping

Michael Lehning, Mathias Thierry Pierre Bavay, Tobias Jonas

Snow water equivalent (SWE) estimates at the end of the winter season have been compared for the 2002–2006 period in a 200 km2 mountainous area in Switzerland, using three different models. The first model, ALPINE3D, is a physically based process-oriented ...

Analytic probability distributions for snow-dominated streamflow

Andrea Rinaldo, Bettina Schaefli, Gianluca Botter

We propose a novel analytical description of the streamflow probability distribution functions (pdfs) in Alpine catchments characterized by pronounced, snow-dominated winter low flows. Knowledge about such hydrological regimes is crucial for water resource ...

Improved snowmelt simulations with a canopy model forced with photo-derived direct beam canopy transmissivity

Michael Lehning

The predictive capacity of a physically based snow model to simulate point-scale, subcanopy snowmelt dynamics is evaluated in a mixed conifer forest, southern Sierra Nevada, California. Three model scenarios each providing varying levels of canopy structur ...

Développement d'un modèle précipitation-débit géomorphologique pour les zones tempérées : Application au bassin versant de la Chamberonne

Cédric Imfeld

The goal of this master thesis was to improve an existing rainfall-runoff model to better represent the dynamics of runoff generation at the catchment scale. The used model is a so-called geomorphological model, which is a spatially explicit hydrological m ...

Hydrologic response of an alpine watershed: Application of a meteorological wireless sensor network to understand streamflow generation

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Marc Diebold, François Ingelrest, Simone Padoan, Silvia Simoni

A field measurement campaign was conducted from June to October 2009 in a 20 km2 catchment of the Swiss Alps with a wireless network of 12 weather stations and river discharge monitoring. The objective was to investigate the spatial variability of meteorol ...

Rainfall thresholds for shallow landslides based on a numerical analysis

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Shallow landslides in Alpine regions frequently occur during heavy precipitation events or extremely fast snow melting processes. Early-warning is mostly based on simple empirical rainfall intensity and duration curves indicating probable critical climatic ...

Spatial and temporal variability of snow depth and SWE in a small mountain catchment

Michael Lehning, Thomas Grünewald

The spatio-temporal variability of the mountain snow cover determines the avalanche danger, snow water storage, permafrost distribution and the local distribution of fauna and flora. Using a new type of terrestrial laser scanner (TLS), which is particularl ...
