Introduction

WaterGAP is a state-of-the-art global-scale water resource and water-use simulation model. WaterGAP was used to support the sustainable development of the Earth system by assessing water scarcity for humans, drought hazards, ecologically-relevant streamflow characteristics, the impacts of human water use and dam construction as well as freshwater-related scenarios of the future [1]. Recent focus has been on quantifying the impact of climate change on the global freshwater system, including the streamflow regime, groundwater recharge, floods, and droughts. WaterGAP is an open-source software with the aim of increasing reproducibility among researchers.
