lfstat: 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.

Authors:Daniel Koffler, Tobias Gauster and Gregor Laaha
