Fragmentation of wind-blown snow crystals

Michael Lehning, Johan Alexandre Philippe Gaume, Francesco Comola, Enrico Paterna

Understanding the dynamics driving the transformation of snowfall crystals into blowing snow particles is critical to correctly account for the energy and mass balances in polar and alpine regions. Here we propose a fragmentation theory of fractal snow cry ...

Energy- and momentum-conserving model of splash entrainment in sand and snow saltation

Michael Lehning, Francesco Comola

Despite being the main sediment entrainment mechanism in aeolian transport, granular splash is still poorly understood. We provide a deeper insight into the dynamics of sand and snow ejection with a stochastic model derived from the energy and momentum con ...

Simulating the influence of snow surface processes on soil moisture dynamics and streamflow generation in an alpine catchment

Michael Lehning, Nander Wever, Francesco Comola, Mathias Thierry Pierre Bavay

The assessment of flood risks in alpine, snow-covered catchments requires an understanding of the linkage between the snow cover, soil and discharge in the stream network. Here, we apply the comprehensive, distributed model Alpine3D to investigate the role ...

Stochastic modeling of snow transport and hydrologic response in alpine terrain

Francesco Comola

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 ...

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

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

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 ...

Efficient global optimization of reservoir geomechanical parameters based on synthetic aperture radar-derived ground displacements

Francesco Comola

When large volumes of fluids are removed from or injected into underground formations for, e.g., hydrocarbon and water production, CO_2 storage, gas storage, and geothermal energy exploitation, monitoring of surface deformations coupled to numerical modeli ...

Scale-dependent effects of solar radiation patterns on the snow-dominated hydrologic response

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola, Mathias Thierry Pierre Bavay, Gianluca Botter, Pierfrancesco Da Ronco

Solar radiation is a dominant driver of snowmelt dynamics and streamflow generation in alpine catchments. A better understanding of how solar radiation patterns affect the hydrologic response is needed to assess when calibrated temperature-index models are ...

Thermodynamics in the hydrologic response: Travel time formulation and application to Alpine catchments

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

This paper presents a spatially-explicit model for hydro-thermal response simulations of Alpine catchments, accounting for advective and non-advective energy fluxes in stream networks characterized by arbitrary degrees of geomorphological complexity. The r ...

Damage pattern and damage progression on breakwater roundheads under multidirectional waves

Francesco Comola, Lorenzo Martinelli

An experimental model test study is carried out to investigate damage pattern and progression on a rock armoured breakwater roundhead subjected to multidirectional waves. Concerning damage pattern, the most critical sector is observed to shift leeward with ...
