Alpine hydropower production and glacier retreat: the case of Switzerland

Pedro Filipe De Almeida Manso, Bettina Schaefli

Hydropower production (HP) in high mountainous areas relies on snow- and glacier melt influenced water resources and is thus highly sensitive to climate warming. Based on the case of Switzerland that produces over 50% of its electricity from hydropower, we ...

New Approach to Identifying Critical Initial Conditions for Extreme Flood Simulations in a Semicontinuous Simulation Framework

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme flood simulation with synthetic extreme precipitation events raises unavoidable questions about the choice of initial conditions. State-of-the-art extreme flood estimation frameworks propose to address these questions with the help of semicontinuou ...

Tapping hidden hydropower potential in Swiss Alpine catchments in the context of the planned nuclear power phase out

Anton Schleiss, Pedro Filipe De Almeida Manso, Bettina Schaefli, Ana Clara Pereira Barbosa Santos

In its Energy Strategy 2050, Switzerland is revising its energy perspectives with a strong focus on renewable sources of energy and in particular hydropower. In this context, the Swiss Government funded a number of competence centers for energy research (S ...

Relevance of the correlation between precipitation and the 0 C isothermal altitude for extreme flood estimation

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme floods are commonly estimated with the help of design storms and hydrological models. In this paper, we propose a new method to take into account the relationship between precipitation intensity (P) and air temperature (T) to account for potential ...

Snow hydrology signatures for model identification within a limits-of-acceptability approach

Bettina Schaefli

Discharge simulation from snow-dominated catchments seems to be an easy task. Any spatially explicit precipitation-runoff model coupled to a temperature-index snow model generally yields simulations that mimic well the observed daily discharges. The robust ...

Improving the theoretical underpinnings of process-based hydrologic models

Bettina Schaefli, Serena Ceola

In this Commentary, we argue that it is possible to improve the physical realism of hydrologic models by making better use of existing hydrologic theory. We address the following questions: (1) what are some key elements of current hydrologic theory; (2) h ...

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 ...
