diffusive: Diffusive model

In EffetsCumulatifsNavigation/ceanav: Research compendium for project on the assessment cumulative effects of marine vessel activities in the St. Lawrence

Diffusive model

Description

Function to evaluate the influence area of a stressor using a passive diffusive model

Usage

diffusive(dat, field, threshold, globalmaximum, decay, distance, increment)

Arguments

dat	sf object with points characterizing stressor intensity
field	character, name of field containing stresseor intensity
threshold	numeric, minimum threshold in percent of the global maximum at which to stop the diffusive model
globalmaximum	global maximum value of the stressor in the study area
decay	percent by which the value of the stressor is reduced when diffusing to the adjacent cells
distance	numeric, distance beyond which the stressor is considered to have no influence. Units are in the units of the spatial object provided.
increment	numeric, distance between successive steps in the model. Units are in the units of the spatial object provided.
