Stream Temperature Evolution in Switzerland: Recent past and future

Bettina Schaefli, Tristan Jonas Brauchli, Michael Lehning, Wolf Hendrik Huwald, Nander Wever, Adrien Michel

Climate change has already affected many components of our natural environment which are well described in the literature. Water temperature has received less interest despite the fact that it is recognized as key variable for assessing water quality of fr ...

Stream temperature and discharge evolution in Switzerland over the last 50 years: annual and seasonal behaviour

Bettina Schaefli, Tristan Jonas Brauchli, Michael Lehning, Wolf Hendrik Huwald, Adrien Michel

Stream temperature and discharge are key hydro- logical variables for ecosystem and water resource management and are particularly sensitive to climate warming. Despite the wealth of meteorological and hydrological data, few studies have quantified observe ...

Small-scale spatio-temporal dynamics of snowmelt and its influence on runoff generation in a high Alpine catchment

Tristan Jonas Brauchli

Snow is one of the most complex materials occurring in nature. In clouds, it can be seen either as a crystal with various shapes or as a freshwater resource that will fall down to the Earth's surface. Once on the ground, it can be described as a thermodyna ...

Influence of slope-scale snowmelt on catchment response simulated with the Alpine3D model

Tristan Jonas Brauchli, Michael Lehning, Wolf Hendrik Huwald, Ernesto Trujillo Gomez

Snow and hydrological modeling in alpine environments remains challenging because of the complexity of the processes affecting the mass and energy balance. This study examines the influence of snowmelt on the hydrological response of a high-alpine catchmen ...

StreamFlow 1.0: an extension to the spatially distributed snow model Alpine3D for hydrological modelling and deterministic stream temperature prediction

Tristan Jonas Brauchli, Michael Lehning, Wolf Hendrik Huwald, Aurélien Gallice, Francesco Comola, Mathias Thierry Pierre Bavay

Climate change is expected to strongly impact the hydrological and thermal regimes of Alpine rivers within the coming decades. In this context, the development of hydrological models accounting for the specific dynamics of Alpine catchments appears as one ...
