m
run of side slopes in channel cross sections (length, but usually expressed as a ratio in relation to rise. e.g. where side side slopes = 1:3.5, m = 3.5)
q
infiltration rate in (length per time, usually mm/hr) (before or after application of safety factor?)
Ra
Existing rise of swale gradient (length, usually m)
Rb
Rise of compensation gradient for an enhanced swale (length, usually m)
SCF
Safety correction factor (dimensionless)
