FFC API Client (R Package)

An R package has been developed that allows users to access the Functional Flows Calculator via an API. The package allows users to:


  • Retrieve streamflow data automatically from USGS or transform user-uploaded streamflow timeseries and run them through the functional flow calculator online,
  • Obtain modeled functional flow metrics for a stream reach (NHD COMID) of interest,
  • Create plots of dimensionless hydrographs using input flow data, and
  • Compare observed and natural functional flow metrics to assess flow alteration at a given location.

The package is available on GitHub.
