aspwb: Simulation in agricultural areas

In medfate: Mediterranean Forest Simulation

Simulation in agricultural areas

Description

Function aspwb_day performs water balance for a single day in an agriculture location. Function aspwb performs water balance for multiple days in an agriculture location.

Usage

aspwbInput(crop_factor, control, soil)

aspwb_day(
  x,
  date,
  meteovec,
  latitude,
  elevation,
  slope = NA_real_,
  aspect = NA_real_,
  runon = 0,
  lateralFlows = NULL,
  waterTableDepth = NA_real_,
  modifyInput = TRUE
)

aspwb(
  x,
  meteo,
  latitude,
  elevation,
  slope = NA_real_,
  aspect = NA_real_,
  waterTableDepth = NA_real_
)

Arguments

crop_factor	Agriculture crop factor.
control	A list with default control parameters (see defaultControl).
soil	An object of class data.frame or soil.
x	An object of class aspwbInput.
date	Date as string "yyyy-mm-dd".
meteovec	A named numerical vector with weather data. See variable names in parameter meteo of spwb.
latitude	Latitude (in degrees).
elevation, slope, aspect	Elevation above sea level (in m), slope (in degrees) and aspect (in degrees from North).
runon	Surface water amount running on the target area from upslope (in mm).
lateralFlows	Lateral source/sink terms for each soil layer (interflow/to from adjacent locations) as mm/day.
waterTableDepth	Water table depth (in mm). When not missing, capillarity rise will be allowed if lower than total soil depth.
modifyInput	Boolean flag to indicate that the input x object is allowed to be modified during the simulation.
meteo	A data frame with daily meteorological data series (see spwb).

Examples

control <- defaultControl()
examplesoil <- defaultSoilParams(4)

x <- aspwbInput(0.75, control, examplesoil)

# Day to be simulated
d <- 100
meteovec <- unlist(examplemeteo[d,-1])
date <- as.character(examplemeteo$dates[d])

#Call simulation function for a single days
sd <- aspwb_day(x, date, meteovec,  
               latitude = 41.82592, elevation = 100) 

#Call simulation function for multiple days
S <- aspwb(x, examplemeteo, latitude = 41.82592, elevation = 100)
