Description

Hydrologic Indices for Daily Time Series Data.

Calculates a suite of hydrologic indices for daily time series data that are widely used in hydrology and stream ecology.

#Hydrostats

hydrostats is a set of tools to compute streamflow indices commonly used in hydrology and ecology such as:

  • basic summary statistics
  • high spells (magnitude, frequency, duration, timing etc.)
  • low spells
  • cease-to-flow spells
  • Colwell's indices
  • partial series
  • baseflow components
	

Most of the functions can be used with the packages plyr and dplyr to return a dataframe of indices based on an additional grouping variable. This allows the analysis (for example) of data from multiple gauges simultaneously, without the need to write a for loop. While most functions return a single row dataframe, several functions will instead return a dataframe of individual spell characteristics for use in subsequent analysis and plotting.
