Calculate pollutant input from runoff area area within a rain event

Usage

area_from_load(load_runoff, Ci_storm, coeff_runoff, q_rain, t_rain)

Arguments

load_runoff

Pollutant load from urban area. Mass unit is one unit larger (factor 1000) as in concentration. For example: if Ci_storm is in ug/L, load must be in mg.

Ci_storm

Concentration in stormwater run-off for substance i.

coeff_runoff

runoff coefficient of runoff area.

q_rain

rain amount in mm/(ha*s)

t_rain

duration of rain in s

Value

Numeric value of the according connectable area in ha
