Nutrient balance based in the application of the Geospatial Regression Equation returning the diffuse, land retention, point sources
Source:R/rgreen.R
region_nut_balance.Rd
Computes the basin nutrient balance.
Usage
region_nut_balance(
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. A value for atmospheric attenuation coefficient.
Examples
# \donttest{
# the data of the TN scenario
data(catch_data_TN)

# the parameter to assess the basin model
alpha_p <- 35.09
alpha_l <- 0.02
sd_coef <- 0.2
# year in which the model should be executed
loc_years <- 1990:2018
