launch_greenR Documentation

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
