HYSETS: 14,425 watershed hydrometeorological database for North America
HYSETS (Hydrometeorological Sandbox: ÉTS): watershed properties, gauging-station discharge, station and gridded precipitation/temperature, infilled meteorology, ERA5/ERA5-Land reanalysis and snow water equivalent for 14,425 North American watersheds, 1950-2018. A very large model-ready hydrologic modelling sandbox.

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: reanalysis
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.
