convolution: Convolution of net rainfall with unit hydrograph

In transfR: Transfer of Hydrograph from Gauged to Ungauged Catchments

Convolution of net rainfall with unit hydrograph

Description

Simulate the discharge by a convolution between the unit hydrograph and the net rainfall.

Usage

convolution(Rn, ...)

## Default S3 method:
convolution(Rn, uh, continuous = FALSE, ...)

## S3 method for class 'units'
convolution(Rn, uh, ...)

## S3 method for class 'transfR'
convolution(
  Rn,
  Rcol = "RnSim",
  Qcol = "Qsim",
  save_donor = FALSE,
  verbose = TRUE,
  ...
)

Arguments

Rn	net rainfall vector or an object of class transfR
...	further arguments passed to or from other methods
uh	unit hydrograph vector
continuous	boolean indicating if, when one time step might be influenced by past or future rainfall (according to the time span of the unit hydrograph), no simulated value is provided
Rcol	name of the space-time attribute for the discharge simulation in the transfR object
Qcol	name of the space-time attribute for the net rainfall in the transfR object
save_donor	boolean indicating if additional discharge simulations should be computed using the net rainfall of each individual donor catchment instead of just the weighted average net rainfall. This requires that save_donor was TRUE when using mixr
verbose	boolean indicating if information messages should be written to the console

Value

An object of the same class of Rn. If Rn is a transfR object, the same transfR object incremented by the new computed attributes.

Examples

data(Oudon)
icatch <- 1
uc <- velocity(hl = Oudon$hl[[icatch]])
uh <- uh(hl = Oudon$hl[[icatch]], uc = uc, deltat = units::set_units(1,"h"))$prob
Rn <- units::set_units(c(1,5,2), "mm/h")
Qsim <- convolution(Rn = Rn, uh = uh)
