CABra: Catchment Attributes for Brazil (Interactive Dataset Explorer)
Large-sample dataset of 735 Brazilian catchments with 30 years (1980-2010) of daily streamflow and climate series plus 100+ attributes across climate, streamflow, groundwater, geology, soil, topography, land cover and hydrologic disturbance. Interactive Shiny app for exploration and download of attributes and boundary shapefiles. Published in HESS 2021.

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
Trend hotspots
Find where water tables are falling year after year.
Because it has: groundwater
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
Gap filling
Rebuild missing well readings from neighbours, rainfall and season.
