Data for streamflow gaging stations in Appalachia

Description

Site characteristics and sample L-moments of annual maximum streamflow for 104 gaging stations in Appalachia.

Usage

Appalach

Format

A data frame with 104 observations on the following 11 variables:

siteid: Character vector: each site's Hydrologic Unit Code, a unique identifier.
lat: Numeric vector: gage latitude, in degrees.
long: Numeric vector: gage longitude, in degrees west of the Greenwich Meridian.
area: Numeric vector: drainage basin area, in square miles.
elev: Numeric vector: gage elevation, in feet.
n: Numeric vector: record length.
mean: Numeric vector: sample mean.
t: Numeric vector: sample L-CV.
t_3: Numeric vector: sample L-skewness.
t_4: Numeric vector: sample L-kurtosis.
t_5: Numeric vector: sample L-moment ratio t_5.

Details

The data in columns lat, long, area and elev, and the streamflow data used to compute the sample L-moments, were obtained from “Hydrodata” CD-ROMs (Hydrosphere, 1993), which reproduce data from the U.S. Geological Survey's WATSTORE data files.

Source

The file appalach.dat in the LMOMENTS Fortran package (Hosking, 1996).
