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 ...

Stream temperature prediction in ungauged basins: review of recent approaches and description of a new physics-derived statistical model

Michael Lehning, Wolf Hendrik Huwald, Marc Parlange, Bettina Schaefli, Aurélien Gallice

The development of stream temperature regression models at regional scales has regained some popularity over the past years. These models are used to predict stream temperature in ungauged catchments to assess the impact of human activities or climate chan ...

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

Andrea Rinaldo, Enrico Bertuzzo, Bettina Schaefli, Ludovico Nicotina, Cédric Imfeld, Pierfrancesco Da Ronco

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 ...

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

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

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 ...

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

Bettina Schaefli, Eva Jakab Toth, 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 ...

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 ...

A robust framework for probabilistic precipitations downscaling from an ensemble of climate predictions applied to Switzerland

André Mermoud, Bettina Schaefli, Xavier Beuchat

Rainfall is poorly modeled by general circulation models (GCMs) and requires appropriate downscaling for local-scale hydrological impact studies. Such downscaling methods should be robust and accurate (to handle, e.g., extreme events and uncertainties), bu ...

Snowfall Limit Forecasts and Hydrological Modeling

Andrea Rinaldo, Cara Christine Tobin, Bettina Schaefli

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- ...

Toward a robust method for subdaily rainfall downscaling from daily data

André Mermoud, Bettina Schaefli, Xavier Beuchat

Compared to daily rainfall data, observed subdaily rainfall times are rare and often very short. For hydrologic modeling, this problem is often addressed by generating synthetic hourly rainfall series, with rainfall generators calibrated on relevant rainfa ...

Integrating point glacier mass balance observations into hydrologic model identification

Bettina Schaefli

The hydrology of high mountainous catchments is often predicted with conceptual precipitation-discharge models that simulate the snow accumulation and ablation behavior of a very complex environment using as only input temperature and precipitation. It is ...
