Hi,
What are the standard values for the infiltration losses in the equation below for rainwater management credit? eg: previous pavements and vegetated roof.
ft = fmin + (fmax – fmin) e-kt
where
ft = infltration rate at time t (in/hr)
fmin = minimum or saturated infltration rate (in/hr)
fmax = maximum or initial infltration rate (in/hr)
k = infltration rate decay factor (/hr)
t = time (hr) measured from time runof frst discharged into infltration area
