Calculate connectable area in a river catchment based on a yearly regulated Substance

Usage

maxArea_year(load_max, Ci_threshold, Ci_storm, coeff_runoff, Q_rain)

load_max: Annual maximal input of substance i. Mass unit corresponds to concentration mass unit (two classes higher. i.e. concentration in mg/L -> load in kg/a.
Ci_threshold: Threshold value for substance i. Concentration unit must fit to Ci_river and Ci_storm.
Ci_storm: Concentration in stormwater run-off for substance i. Concentration unit must fit to Ci_threshold and Ci_river.
coeff_runoff: Run-off coefficient of connected impervious area
Q_rain: Annual amount of rain amount in mm/a
