NVE Hydrological API (HydAPI)
RESTful API from the Norwegian Water Resources and Energy Directorate (NVE) exposing the archive of historical and active hydrological time series (discharge, water stage, water temperature) from ~1800 stations, continuously updated. Distinct from the Sildre web portal already in the directory.

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
Risk screening
Screen projects and assets for climate risk.
Because it has: Water Temperature
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
Bias correction
Correct and downscale climate model output for a site.
