A quantitative evaluation of the issue of drought definition: A source of disagreement in future drought assessments (2021)
Journal Article

Droughts are anticipated to intensify in many parts of the world due to climate change. However, the issue of drought definition, namely the diversity of drought indices, makes it difficult to compare drought assessments. This issue is widely known,...

Understanding each other’s models: an introduction and a standard representation of 16 global water models to support intercomparison, improvement, and communication (2021)
Journal Article

Global water models (GWMs) simulate the terrestrial water cycle on the global scale and are used to assess the impacts of climate change on freshwater systems. GWMs are developed within different modelling frameworks and consider different underlying...

Uncertainty of simulated groundwater recharge at different global warming levels: A global-scale multi-model ensemble study (2021)
Journal Article

Billions of people rely on groundwater as being an accessible source of drinking water and for irrigation, especially in times of drought. Its importance will likely increase with a changing climate. It is still unclear, however, how climate change w... Read More about Uncertainty of simulated groundwater recharge at different global warming levels: A global-scale multi-model ensemble study.

Understanding each other's models: a standard representation of global water models to support improvement, intercomparison, and communication (2021)
Working Paper

Global water models (GWMs) simulate the terrestrial water cycle, on the global scale, and are used to assess the impacts of climate change on freshwater systems. GWMs are developed within different modeling frameworks and consider different underlyin...

Projecting Exposure to Extreme Climate Impact Events Across Six Event Categories and Three Spatial Scales (2020)
Journal Article

©2020. The Authors. The extent and impact of climate-related extreme events depend on the underlying meteorological, hydrological, or climatological drivers as well as on human factors such as land use or population density. Here we quantify the pure... Read More about Projecting Exposure to Extreme Climate Impact Events Across Six Event Categories and Three Spatial Scales.

How evaluation of global hydrological models can help to improve credibility of river discharge projections under climate change (2020)
Journal Article

© 2020, The Author(s). Importance of evaluation of global hydrological models (gHMs) before doing climate impact assessment was underlined in several studies. The main objective of this study is to evaluate the performance of six gHMs in simulating o...

Historical and future changes in global flood magnitude - evidence from a model-observation investigation (2020)
Journal Article

© Author(s) 2020. To improve the understanding of trends in extreme flows related to flood events at the global scale, historical and future changes of annual maxima of 7 d streamflow are investigated, using a comprehensive streamflow archive and six...

Exploring the value of machine learning for weighted multi-model combination of an ensemble of global hydrological models (2019)
Journal Article

This study presents a novel application of machine learning to deliver optimised, multi-model combinations (MMCs) of Global Hydrological Model (GHM) simulations. We exemplify the approach using runoff simulations from five GHMs across 40 large global...

Evapotranspiration simulations in ISIMIP2a—Evaluation of spatio-temporal characteristics with a comprehensive ensemble of independent datasets (2018)
Journal Article

© 2018 The Author(s). Actual land evapotranspiration (ET) is a key component of the global hydrological cycle and an essential variable determining the evolution of hydrological extreme events under different climate change scenarios. However, recent... Read More about Evapotranspiration simulations in ISIMIP2a—Evaluation of spatio-temporal characteristics with a comprehensive ensemble of independent datasets.

Worldwide evaluation of mean and extreme runoff from six global-scale hydrological models that account for human impacts (2018)
Journal Article

Global-scale hydrological models are routinely used to assess water scarcity, flood hazards and droughts worldwide. Recent efforts to incorporate anthropogenic activities in these models have enabled more realistic comparisons with observations. Here...
