RMintensity

Description

Function to compute maximum x-minute rainfall intensities in units of depth/hr

Usage

RMintensity(
  df,
  date = "r.date",
  rain = "rain",
  df.events,
  sdate = "StartDate",
  edate = "EndDate",
  depth = "depth",
  xmin = c(60, 180, 360)
)

Arguments

df	dataframe
date	string Date column name in df as POSIX
rain	string Column name in df with instantaneous rain values
df.events	dateframe with start and end dates/times for events
sdate	string Start date column in df.events rain file as POSIX
edate	string End date column in df.events rain file as POSIX
depth	string rain depth in event file, defaults to "depth",
xmin	vector vector of values representing X-minute max rainfall requested

Value

df.events dataframe, X-hour maximum rainfall intensities

Examples

RDB <- CedarRRain
RDB2 <- RMprep(RDB,
               prep.type=1,
               date.type=1,
               dates.in="CST.Time",tz="CST6CDT")
RDB3 <- subset(RDB2,
upload.ph3_site_basin_cedar_creek.Id.0....Geographical.Mean.kg.m.2.>-1)
event.list <- RMevents(df=RDB3,
                       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
intensities <- RMintensity(RDB3,date="pdate",
rain="upload.ph3_site_basin_cedar_creek.Id.0....Geographical.Mean.kg.m.2.",
events.0.2,sdate="StartDate",edate="EndDate",depth="rain",xmin=c(5,15,30))
