Stochastic modeling of snow transport and hydrologic response in alpine terrain

The scientific community has developed a keen interest in the processes driving the hydrologic cycle in alpine regions. The concern mainly stems from the vulnerability of snow-covered environments to the warming temperatures, such that entire ecological an ...

Development of a methodology for extreme flood estimations in alpine catchments for the verification of dam safety

Fränz Zeimetz

Dams are critical infrastructures which may be endangered by natural hazards as extreme foods. The water release structures especially the spillways must be designed in such a way that they can ensure the safe passage of extreme floods. Uncontrolled overto ...

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

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

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 ...

Snowmelt observations at the slope scale and implications for the catchment response using the Alpine3D model

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

Snowpack and especially its melt during spring is a crucial resource for water availability in mountainous regions. A better understanding of the processes and their representation in hydrological models is therefore necessary for different purposes, such ...

Field study on drainage densities and rescaled width functions in a high‐altitude alpine catchment

Andrea Rinaldo, Marc Parlange, Raphaël Mutzner

This paper addresses the effect of accurately mapping spatially heterogeneous drainage densities in high-altitude alpine basins on Rescaled Width Functions (RWFs), used in some applications as a minimalist model of the hydrologic response. The channel netw ...

Transit times-the link between hydrology and water quality at the catchment scale

Paolo Benettin

In spite of trying to understand processes in the same spatial domain, the catchment hydrology and water quality scientific communities are relatively disconnected and so are their respective models. This is emphasized by an inadequate representation of tr ...

Sensitivity of Alpine3D modeled snow cover to modifications in DEM resolution, station coverage and meteorological input quantities

Michael Lehning, Mathias Thierry Pierre Bavay, Sebastian Schlögl

This study presents a comprehensive sensitivity and uncertainty assessment of important input parameters on the Alpine3D modeled snow water equivalent (SWE) for two different alpine catchments. Horizontal resolution of the DEM grid, station coverage and se ...

Local tributary widening for river rehabilitation

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

The hydro-morpho-sedimentary processes in confluence hydrodynamic zones (CHZ) subject to a local widening of the tributary were investigated in a series of laboratory experiments that were representative of the 20 major confluences of the Upper Rhone River ...

Controls on the diurnal streamflow cycles in two subbasins of an alpine headwater catchment

Marc Parlange, Steven Vincent Weijs, Marc Calaf Bracons, Holly Jayne Oldroyd, Raphaël Mutzner

In high-altitude alpine catchments, diurnal streamflow cycles are typically dominated by snowmelt or ice melt. Evapotranspiration-induced diurnal streamflow cycles are less observed in these catchments but might happen simultaneously. During a field campai ...
