What can we learn by transposing the calibration – validation paradigm into a multi-objective context ?

André Musy, Bettina Schaefli

The classical single-objective model calibration and validation approach using different time periods for each of them is known not to be sufficient to judge whether the model predictions are consistent or to detect model structural deficiencies. It is how ...

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 ...

An analytical model for soil-atmosphere feedback

Bettina Schaefli

Soil-atmosphere feedback is a key for understanding the hydrological cycle and the direction of potential system changes. This paper presents an analytical framework to study the interplay between soil and atmospheric moisture, using as input only the boun ...

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 ...

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

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

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 ...

Projecting hydropower production under future climates: a guide for decision-makers and modelers to interpret and design climate change impact assessments

Bettina Schaefli

Hydropower is a key energy source in almost all world regions. It fuels social and economic development, ensures electricity security, and is a pillar for renewable electricity production. But hydropower and its environmental impacts are vulnerable to clim ...

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 ...

SEHR-ECHO v1.0: a Spatially Explicit Hydrologic Response model for ecohydrologic applications

Andrea Rinaldo, Enrico Bertuzzo, Bettina Schaefli, Ludovico Nicotina

This paper presents the Spatially Explicit Hydrologic Response (SEHR) model developed at the Laboratory of Ecohydrology of the Ecole Polytechnique Fédérale de Lausanne for the simulation of hydrological processes at the catchment scale. The key concept of ...

Swiss Rainfall Mass Curves and their Influence on Extreme Flood Simulation

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

Extreme flood estimates for dam safety are routinely obtained from hydrologic simulations driven by selected design storms. The temporal structure of such design storms can be obtained from Rainfall Mass Curves (RMCs), which are adimensionalized curves of ...

Snowfall Limit Forecasts and Hydrological Modeling

Andrea Rinaldo, Bettina Schaefli, Cara Christine Tobin

Hydrological flood forecasting in mountainous areas requires accurate partitioning between rain and snowfall to properly estimate the extent of runoff contributing areas. Here a method to make use of snowfall limit information-a standard output of limited- ...

A conceptual glacio-hydrological model for high mountainous catchments

André Musy, Bettina Schaefli, Markus Niggli

In high mountainous catchments, the spatial precipitation and therefore the overall water balance is generally difficult to estimate. The present paper describes the structure and calibration of a semi-lumped conceptual glaciohydrological model for the joi ...

Panta Rhei-Everything Flows: Change in hydrology and society-The IAHS Scientific Decade 2013-2022

Bettina Schaefli, Harshit Gupta

The new Scientific Decade 2013-2022 of IAHS, entitled Panta RheiEverything Flows, is dedicated to research activities on change in hydrology and society. The purpose of Panta Rhei is to reach an improved interpretation of the processes governing the water ...

Improving the degree-day method for sub-daily melt simulations with physically-based diurnal variations

Andrea Rinaldo, Marc Parlange, Bettina Schaefli, Guillermo Barrenetxea Kobas, Ludovico Nicotina, Cara Christine Tobin

This paper proposes a new extension of the classical degree-day snowmelt model applicable to hourly simulations for regions with limited data and adaptable to a broad range of spatially-explicit hydrological models. The snowmelt schemes have been tested wi ...

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 ...

Dataset for: Future water temperature of rivers in Switzerland under climate change investigated with physics-based models

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

This work presents the first extensive study of climate change impacts on rivers temperature in Switzerland. Results show that even for low emissions scenarios, water temperature increase will lead to adverse effect for both ecosystems and socioeconomic se ...

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

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

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 ...
