This dataset was generated as part of the Horizon Europe project STARS4Water, which is dedicated to collecting and providing access to existing and newly developed datasets for future water resources management. The data entails a set of indicators for assessing climate risks and impacts on integrated water resources systems. More datasets will be added later-on in the project. This first tier is a set of indicators that are directly derived from readily available datasets from e.g. the Copernicus Climate Data Store. The future projections are simplified by projecting them onto (sub)catchments and by reducing the numberof scenarios. This makes them easier to handle by river basin managers and for usages in dashboards.
