toxicIntensity: Method toxicIntensity

Description

Simulate contaminants intensity over the landscape.

Usage

toxicIntensity(objectL, ...)
## S3 method for class 'Landscape':
toxicIntensity(objectL, toxic_emission, mintime = 1,
  maxtime = 60, size_raster = 2^10, kernel = "NIG",
  kernel.options = list(h = 2, mu = 2, theta = 0, gamma = -2.59),
  beta = 0.4, alpha = list(minalpha = 0.1, maxalpha = 0.95,
  covariate_threshold = 30, simulate = T, covariate = NULL))

Arguments

objectL

A Landscape object

...

parameters

toxic_emission

Matrix of sources emissions, row as sources ID, col as time

mintime

Start simulation time (default=1)

maxtime

End simulation time

size_raster

raster size (default = 2^10)

kernel

dispersion kernel, function name (default=NIG)

kernel.options

kernel function parameters

beta

toxic adherence parameter between 0 and 1 included

alpha

list of loss options

Value

• A 3D array as time matrix dispertion, [t,x,y]

Details

The dispersal of contaminants is implemented by rastering the landscape and by computing the convolution.

Local intensity depends of beta and alpha parameters.
