Hydrovol

Description

Computes volumes and max discharge for hydrographs given the discharge time series and the begin and end dates and times of the hydrographs. Dates must be in POSIXct format.

Usage

Hydrovol(
  dfQ,
  Q = "Q",
  time = "pdate",
  df.dates,
  bdate = "bpdate",
  edate = "epdate",
  volume = "event.vol",
  Qmax = "Qmax",
  duration = "Eduration"
)

Arguments

dfQ	dataframe with Q and time
Q	string name of column in dfQ with Q, defaults to "Q"
time	string name of column in dfQ with POSIXct time, defaults to "pdate"
df.dates	dataframe with begin and end dates/times in POSIXct format
bdate	string begin date in POSIXct column name, defaults to "bpdate"
edate	string end date in POSIXct column name, defaults to "epdate"
volume	string name of resulting volume variable, defaults to "event.vol"
Qmax	string name of Qmax variable, defaults to "Qmax"
duration	string name of resulting duration variable, defaults to "Eduration"

Value

df.dates2 dataframe

Examples

sampleData <- sampleData
flowData <- flowData
Hydrovol(dfQ=flowData,Q="Q",time="pdate",
         df.dates=sampleData,bdate="Hbpdate",edate="Hepdate")
