OpenHi.net (Open Hydrosystem Information Network)
National-scale integrated infrastructure for collecting, managing and freely disseminating hydrological and environmental data on Greece's surface waters, aggregating real-time telemetry from rivers, lakes and terrain plus partner databases. Built by NTUA/ITIA and partners on the Enhydris platform.

What you can do with it
Typical work that data of this type supports.
- 01
Design flows
Estimate 1-in-50 and 1-in-100 year floods for bridges, culverts and spillways.
Because it has: Streamflow
- 02
Low flows
Set environmental flows and check what is left in the river in a dry year.
- 03
Storage tracking
Follow storage and releases through the season.
Because it has: Water Level
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Flow forecasting
Train LSTM-style models on past records to forecast river levels and flow days ahead.
- 02
Ungauged basins
Combine with catchment data to estimate flow where there is no gauge.
- 03
Storage from space
Estimate volume from satellite water area and altimetry.
