For R-using hydrologists, there is a new package on CRAN that is well worth checking. Nick Bond has put together a collection of functions and data related to hydrologic statistics.
The hydrostats package includes tools to compute commonly used streamflow indices 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
There is also daily data sets for the Acheron River and Coopers Creek.
For details see:
If you are interested in floods, the
partial.series function is particularly useful. It will identify the largest independent flood events in a record of daily flows. You can specify the independence criteria and the number of events to be returned. An example for the Acheron River is shown below.
