Peak {extRemes} | R Documentation |
Peak stream flow data from 1924 through 1999 for the Salt River near Roosevelt, Arizona.
data(Peak)
A data frame with 75 observations on the following 2 variables.
Peak stream flow in cfs (1 cfs=0.028317 $m^3/s$) data for water years (October through September) from 1924 through 1999 for the Salt River near Roosevelt, Arizona. Data for 1986 are missing. Also includes seasonal mean Darwin pressures (mb–1000).
Several analyses have been performed on streamflow at this location (see, e.g., Anderson and Meerschaert (1998), Dettinger and Diaz (2000); and, for extreme stream flow, Katz et al. (2002) Sec. 5.2.2).
