CalcFdc: Calculate flow duration curve statistics
In NCAR/rwrfhydro: R tools for the WRF Hydro Model

Description Usage Arguments Details Value See Also Examples

CalcFdc calculates flow exceedance probabilities and adds them as a new column to the dataframe.

1	CalcFdc(strDf, strCol = "q_cms")

`strDf`	The streamflow time series dataframe (e.g., output from `ReadFrxstPts` or `ReadUsgsGage`). The data frame must contain a column of streamflow values.
`strCol`	The name of the column containing the streamflow values (DEFAULT="q_cms").

CalcFdc reads a streamflow time series dataframe (modeled or observed) and outputs a modified dataframe with calculated percent exceedances.

A dataframe containing the original input data with a new column added called "<strCol>.fdc" containing the flow exceedance probabilities.

## Take the time series of observed 5-minute streamflow values for Fourmile 
## Creek (stored in the dataframe obsStr5min.fc in the column "q_cms") and 
## return the same dataframe with a new column called "q_cms.fdc"
## containing the flow exceedance probabilities.
## Not run: 
obsStr5min.fc <- CalcFdc(obsStr5min.fc, "q_cms")

## End(Not run)
