Rating Curve Development

Hydrometric Rating Application (HydRA)

HydRA is a free and publicly available software published by the BC government. It allows users to upload any stage-discharge datasets and automatically optimizes a rating equation. Users can manipulate rating parameters to optimize the rating fit for single or multi-segment rating curves. The app produces a summary report and equation that can be used to convert continuous stage datasets into continuous discharge datasets.
