DanubeHIS, the Danube River Basin Hydrological Information System, provides public access to hydrological and meteorological information for the Danube River Basin. The website presents river conditions through near-real-time measurements and validated time series collected from data providers across the basin. Users can explore river discharge, water levels, water temperature, and hourly or daily precipitation, with options to browse information by country, river, or sub-basin.

DanubeHIS offers measurement overviews, station details, maps, and tables to help visitors locate and review observations. Its latest-measurement pages highlight current readings and recent changes, while time-series tools support examination of historical and updated data. The site also provides information about monitoring stations, observed properties, data access and usage, and applicable data policies and licenses. A high-contrast mode and user login are available among its site features.

The system is associated with the International Commission for the Protection of the Danube River (ICPDR), which is identified as the website’s publisher.
