A two-layer canopy model with thermal inertia for an improved snowpack energy balance below needleleaf forest (model SNOWPACK, version 3.2.1, revision 741)
Michael Lehning, Isabelle Amandine Gouttevin, Tobias Jonas
A new, two-layer canopy module with thermal inertia as part of the detailed snow model SNOWPACK (version 3.2.1) is presented and evaluated. As a by-product of these new developments, an exhaustive description of the canopy module of the SNOWPACK model is p ...
Copernicus Gesellschaft Mbh2015Liquid water flow in snow and hydrological implications
The presence of a snow cover has a strong impact on hydrological processes. In this thesis, the role of the snow cover as an interface between the atmosphere and the soil is assessed. An implementation of a solver for Richards Equation (RE) for water flow ...
EPFL2015Influence of snow cover properties on avalanche dynamics
Snow avalanches are a direct thread to many mountain communities around the world and already small avalanches can endanger traffic routes and result in loss of life or property. Their destructive power depends, among other things, on the overall mass and ...
EPFL2015Evaluating snow models with varying process representations for hydrological applications
Much effort has been invested in developing snow models over several decades, resulting in a wide variety of empirical and physically based snow models. For the most part, these models are built on similar principles. The greatest differences are found in ...
American Geophysical Union2015Verification of the multi-layer SNOWPACK model with different water transport schemes
Michael Lehning, Nander Wever, Charles Fierz
The widely used detailed SNOWPACK model has undergone constant development over the years. A notable recent extension is the introduction of a Richards equation (RE) solver as an alternative for the bucket-type approach for describing water transport in th ...
2015Snowmelt as a driver of ecosystem response in water limited mountain forests of the Western U.S.
Recent large-scale changes in snow cover over Western North America associated with climate warming may have widespread impacts on water availability. These changes have potentially varied impacts on water availability as snowmelt influences, soil moisture ...
2015Model simulations of the modulating effect of the snow cover in a rain-on-snow event
Michael Lehning, Nander Wever, Charles Fierz, Tobias Jonas
In October 2011, the Swiss Alps underwent a marked rain-on-snow (ROS) event when a large snowfall on 8 and 9 October was followed by intense rain on 10 October. This resulted in severe flooding in some parts of Switzerland. Model simulations were carried o ...
European Geosciences Union2014Solving Richards Equation for snow improves snowpack meltwater runoff estimations in detailed multi-layer snowpack model
Michael Lehning, Nander Wever, Charles Fierz
The runoff from a snow cover during spring snowmelt or rain-on-snow events is an important factor in the hydrological cycle. In this study, three water balance schemes for the 1 dimensional physically-based snowpack model SNOWPACK are compared to lysimeter ...
European Geosciences Union2014Record-setting forest stress in the Rocky Mountains caused by low snowfall and high potential evapotranspiration, consistent with expected future conditions
Projections of future climate for the Southwestern U.S. and other semi-arid regions globally include reductions in mountain snow accumulation and increased summer potential evapotranspiration. These changes may significantly alter runoff production, evapot ...
2014Comparison between open-site and below-canopy climatic conditions in Switzerland for different types of forests over 10 years (1998-2007)
Martine Rebetez, Valentine Renaud
We compared below-canopy and open-site climatic conditions for 14 different forest sites in Switzerland and analysed the forest influence on local summer and winter climate according to the forest type (coniferous, mixed, deciduous), soil type, slope orien ...
