Arguments

x

[GRiwrm object] diagram of the semi-distributed model (See CreateGRiwrm)

DatesR

POSIXt vector of dates

Precip

(optional) matrix or data.frame frame of numeric containing precipitation in [mm per time step]. Column names correspond to node IDs

PotEvap

(optional) matrix or data.frame frame of numeric containing potential evaporation [mm per time step]. Column names correspond to node IDs

Qobs

(optional) matrix or data.frame frame of numeric containing observed flows in [mm per time step]. Column names correspond to node IDs

PrecipScale

(optional) named vector of logical indicating if the mean of the precipitation interpolated on the elevation layers must be kept or not, required to create CemaNeige module inputs, default TRUE (the mean of the precipitation is kept to the original value)

TempMean

(optional) matrix or data.frame of time series of mean air temperature [°C], required to create the CemaNeige module inputs

TempMin

(optional) matrix or data.frame of time series of minimum air temperature [°C], possibly used to create the CemaNeige module inputs

TempMax

(optional) matrix or data.frame of time series of maximum air temperature [°C], possibly used to create the CemaNeige module inputs

ZInputs

(optional) named vector of numeric giving the mean elevation of the Precip and Temp series (before extrapolation) [m], possibly used to create the CemaNeige module input

HypsoData

(optional) matrix or data.frame containing 101 numeric rows: min, q01 to q99 and max of catchment elevation distribution [m], if not defined a single elevation is used for CemaNeige

NLayers

(optional) named vector of numeric integer giving the number of elevation layers requested -, required to create CemaNeige module inputs, default=5

...

used for compatibility with S3 methods

Value

A GRiwrmInputsModel object which is a list of InputsModel objects created by airGR::CreateInputsModel with one item per modeled sub-catchment.

Details

Meteorological data are needed for the nodes of the network that represent a catchment simulated by a rainfall-runoff model. Instead of airGR::CreateInputsModel that has numeric vector as time series inputs, this function uses matrix or data.frame with the id of the sub-catchment as column names. For single values (ZInputs or NLayers), the function requires named vector with the id of the sub-catchment as name item. If an argument is optional, only the column or the named item has to be provided.

See airGR::CreateInputsModel documentation for details concerning each input.

Examples

###################################################################
# Run the `airGR::RunModel_Lag` example in the GRiwrm fashion way #
# Simulation of a reservoir with a purpose of low-flow mitigation #
###################################################################

## ---- preparation of the InputsModel object

## loading package and catchment data
library(airGRiwrm)
data(L0123001)

## ---- specifications of the reservoir

## the reservoir withdraws 1 m3/s when it's possible considering the flow observed in the basin
Qupstream <- matrix(-sapply(BasinObs$Qls / 1000 - 1, function(x) {
  min(1, max(0, x, na.rm = TRUE))
}), ncol = 1)

## except between July and September when the reservoir releases 3 m3/s for low-flow mitigation
month <- as.numeric(format(BasinObs$DatesR, "%m"))
Qupstream[month >= 7 & month <= 9] <- 3
Qupstream <- Qupstream * 86400 ## Conversion in m3/day

## the reservoir is not an upstream subcachment: its areas is NA
BasinAreas <- c(NA, BasinInfo$BasinArea)

## delay time between the reservoir and the catchment outlet is 2 days and the distance is 150 km
LengthHydro <- 150
## with a delay of 2 days for 150 km, the flow velocity is 75 km per day
Velocity <- (LengthHydro * 1e3 / 2) / (24 * 60 * 60) ## Conversion km/day -> m/s
