Calculation of Low Flow Statistics for Daily Stream Flow Data

The "Manual on Low-flow Estimation and Prediction", published by the World Meteorological Organisation (WMO), gives a comprehensive summary on how to analyse stream flow data focusing on low-flows. This packages provides functions to compute the described statistics and produces plots similar to the ones in the manual.

News

lfstat 0.9.4

New Functionality

  • new function ev_return_period() for computing return periods of flow quantiles

  • the start of a hydrogical year can now be set and retrieved for individual objects with hyear_start()

  • discharge units of a time series can be set and retrieved with flowunit()

Changes

  • fixing imports/exports for reverse dependency RcmdrPlugin.lfstat

  • correcting internal data sets

  • improve creation and coercion to class lfobj

  • tyears() and tyearsn() now have a default argument for dist

  • find_droughts() accepts threshold quantiles as character strings

  • summary.lfobj is more verbose

  • MAM() issues a warning in case of to few observations
