Hydrologic Indices for Daily Time Series Data.
#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.
