UH: Transfer function

In HBV.IANIGLA: Modular Hydrological Model

Transfer function

Description

Use a triangular transfer function to adjust the timing of the simulated streamflow discharge. This module represents the runoff routing in the streams.

Usage

UH(
  model,
  Qg,
  param
  )

Arguments

model	numeric integer with the transfer function model. The current HBV.IANIGLA model only allows for a single option. 1: triangular function with a static base.
Qg	numeric vector with the water that gets into the stream. If you are not modeling glaciers is the output of the Routing_HBV module, otherwise, is the sum of the Routing_HBV output plus the glacier discharge coming from the Glacier_Disch module.
param	numeric vector with the following values, Model 1 Bmax: base of the transfer function triangle [timestep].

Value

Numeric vector with the simulated streamflow discharge.

Examples

# The following is a toy example. I strongly recommend to see
# the package vignettes in order to improve your skills on HBV.IANIGLA

## Routing example
inputMatrix <- cbind(runif(n = 200, max = 100, min = 0), runif(n = 200, max = 50, min = 5),
                 runif(n = 100, max = 3, min = 1))

routeMod1   <- Routing_HBV(model = 1, lake = TRUE, inputData = inputMatrix,
                         initCond = c(10, 15, 20), param = c(0.1, 0.05, 0.001, 1, 0.8))

## UH
dischOut <- UH(model = 1, Qg = routeMod1[ , 1], param = 2.2)
