launch_green: GREEN execution

In GREENeR: Geospatial Regression Equation for European Nutrient Losses (GREEN)

GREEN execution

Description

Applies the model GREEN (Grizzetti et al. [@grizzetti2012changes, @grizzetti2021eu]) to a basin and returns annual nutrient (nitrogen or phosphorus) load for all catchments in the basin

Usage

launch_green(
  catch_data,
  annual_data,
  alpha_p,
  alpha_l,
  sd_coef,
  loc_years,
  atm_coeff = 0.38
)

Arguments

catch_data	data frame. Definition of the topological sequence of catchments.
annual_data	data frame. Sources of nutrient for each year and catchments.
alpha_p	numeric. First model parameter, the basin retention coefficient.
alpha_l	numeric. Second model parameter, the river retention coefficient.
sd_coef	numeric. Third model parameter, fraction of domestic diffuse sources that reaches the stream network.
loc_years	integer. Years in which the model should be executed.
atm_coeff	numeric. It defines the atmospheric attenuation coefficient.

Value

One object, a data frame
