Runoff volume is calculated using the Rational Method to determine runoff flow at the outlet of the industrial SWM zone. The flow volume is calculated by multiplying the flow rate by the catchment time of concentration (16 hours for the Heathcote River catchment). The results of the calculation indicate the optimum runoff volume, which can be managed within a green stormwater infrastructure network in the SWM zone.
