ngaruroro: Daily stream flow data used for low flow analysis

In lfstat: Calculation of Low Flow Statistics for Daily Stream Flow Data

Description

This data set provides the streamflow records for the rivers Ngaruroro (New Zealand) and Ray (UK). They are provided as a low flow object (lfobj) as used in the package lfstat. The user might want to perform analysis with shorter time series. The data set ng just contains the eighties (hydrological year 1980 – 1989) of the Ngaruroro discharges.
