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.
