R Documentation
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.
