Research

Alpine Hydroclimatology
Observations and modelling of spatial and temporal distribution of hydrological and climatological processes in Alpine and Arctic regions. Processes studied: snow accumulation and ablation, snow cover distribution in arctic and subalpine regions, topographic and vegetation effects on snow cover evolution and climatologic variables, snow redistribution, land surface energy balance during rain on snow conditions, runoff generation during rain on snow flood events, effect of future scenarios on snow accumulation and ablation and on arctic landscapes (permafrost processes), river and lake ice cover evolution, water balance assessments.

General Hydrology
Isotope Hydrology: Influence of the vegetation structure on isotope content of throughfall and soil water, isotopic composition of flood water related to runoff source.
Hydrology of extreme events: Assessment and improvement of flood forecast models, simulation of extreme floods caused by historic, intense, short duration rainfall events, flood mitigation and prevention adaptations.
