In USGS-R/Rainmaker: Rainfall event processing

RMevents

Description

Compute rainfall event variables based on time series of rain data with only one rain gage or one mean radar rain column.

Usage

RMevents(df, ieHr = 6, rainthresh = 5.1, rain = "rain", time = "pdate")

Arguments

df	dataframe with rainfall
ieHr	numeric Interevent period in hours, defaults to 6,
rainthresh	numeric Minimum event depth in units of the rain column, default is given as 5.1 assuming millimeters (0.2")
rain	string Column name of rainfall unit values, defaults to "rain"
time	string column with as.POSIXctdate, defaults to "pdate"

Details

Rainfall event determination

Value

list of all rain events that surpass rainthresh (storms2) and all rain events (storms). Also returns all a data frame of all rain observations > 0 with the associated date/time and assigned event number (tipsbystorm) and the minimum time difference between observations (timeInterval)

Examples

RDB <- CedarRRain
RDB2 <- RMprep(RDB,
               prep.type = 1,
               date.type = 1,
               dates.in = "CST.Time",
               tz = "CST6CDT")
event.list <- RMevents(df = RDB2,
                       ieHr = 6,
                       rainthresh = 0.2,
                       rain = "upload.ph3_site_basin_cedar_creek.Id.0....Geographical.Mean.kg.m.2.")
events.0.2 <- event.list$storms2
