💧 We have kicked off the upgrade of EU-Hydro! 💧

Confluvio is proud to be part of this exciting project. As a reference dataset in the CLMS portfolio, EU-Hydro provides detailed insights into water resources. It combines data from various sources — including the Copernicus Digital Elevation Model (COP-DEM) and national hydrographic datasets from member countries, as well as space-based imagery — to deliver information on the physical characteristics and geographical distribution of Europe's water bodies.

The new EU-Hydro suite of products will be produced for all river basins covering the EEA38. One of the main novelties will be the availability of raster layers — such as hydrologically conditioned DEM, flow direction map, and flow accumulation map — derived from the state-of-the-art COP-DEM 10 m. Other important additions will be a topologically consistent river network, water bodies and watersheds. The EU-Hydro updates will also include a newly delineated, up-to-date coastline dataset, as well as a specific layer on artificial structures such as barriers and dams, all topologically consistent with the river network.

The updated version of EU-Hydro will support a wide range of applications within the hydrological domain. Examples are water resource assessment and water quality evaluation. Its potentially crucial role for our society is further emphasised by the rising frequency of natural disasters, such as droughts and floods. With its high-quality, free, and openly accessible data, EU-Hydro will help address these challenges, which urgently call for enhanced water resilience in Europe — as reflected in this year’s edition of the EU Green Week.

The work will be carried out by an international consortium operating under the leadership of GAF and including Telespazio Ibérica, e-GEOS and, as subcontractors, DLR and yours truly, Confluvio.
