CAMELS (US): Catchment Attributes and Meteorology for Large-sample Studies

The original CAMELS dataset: daily hydrometeorological forcing (Daymet, NLDAS, Maurer), USGS streamflow, and catchment attributes (topography, climate, soil, geology, land cover, hydrologic signatures) for 671 minimally disturbed catchments across the contiguous United States, 1980-2014. The reference AI/ML-ready large-sample hydrology benchmark used to train LSTM rainfall-runoff models.

What you can do with it

Typical work that data of this type supports.

  1. 01

    Design flows

    Estimate 1-in-50 and 1-in-100 year floods for bridges, culverts and spillways.

    Because it has: streamflow

  2. 02

    Low flows

    Set environmental flows and check what is left in the river in a dry year.

  3. 03

    Design storms

    Build rainfall intensity-duration-frequency curves for drainage design.

Where AI adds value

Ideas for machine learning and AI agents built on this kind of data.

  1. 01

    Flow forecasting

    Train LSTM-style models on past records to forecast river levels and flow days ahead.

  2. 02

    Ungauged basins

    Combine with catchment data to estimate flow where there is no gauge.

  3. 03

    Downscaling

    Turn coarse rainfall grids into field or ward scale estimates.
