eWaterCycle
Software package & platform for mid-to-long term hydrological modelling research
eWaterCycle is an open-source software platform that enables researchers to build, run, and analyze hydrological models in a reproducible and interoperable way. It integrates multiple hydrological models, observational datasets, and computational workflows within a common framework, making it easier to compare model outputs and conduct long-term water system simulations. By supporting scenario analysis of water availability, droughts, floods, and other hydrological extremes under changing climate conditions, eWaterCycle helps researchers and decision-makers assess climate impacts and develop evidence-based adaptation strategies.
