convolution function

Convolution of net rainfall with unit hydrograph

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

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

Returns

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)
