Editor(s): GMD topic editors | Coordinators: Petra Döll (Goethe University Frankfurt, Germany), Hannes Müller Schmied (Goethe University Frankfurt, Germany), and Martina Flörke (Ruhr University Bochum, Germany) Special issue jointly organized between Geoscientific Model Development and Natural Hazards and Earth System Sciences

This special issue gathers already-published and future papers that describe and/or apply the global water resources and use model WaterGAP.

WaterGAP (www.watergap.de) is a global freshwater model that calculates human water use as well as water flows and storage on all continents (except Antarctica), taking into account the human influence on the natural freshwater system such as climate change, water abstractions, and dams. As one of the pioneers in the field of global hydrological modelling, it supports our understanding of the global freshwater system since 1996 for historical periods and the future. The model is continuously being improved to answer scientific questions driven by societal demands. WaterGAP is applied to assess water scarcity, droughts, and floods and to quantify the human impact on, for example, groundwater, wetlands, streamflow, and sea-level rise.

Review process: all papers of this special issue underwent the regular interactive peer-review process of Geoscientific Model Development handled by members of the GMD editorial board.
