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: hydrology
- 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.
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.
