This study investigates and analyses flow and nutrient runoff from the Bartram Road catchment, Western Australia. This catchment was developed using the principle of ‘detention and water quality treatment of minor events’, as defined in Australian rainfall and runoff (I.E.Aust. 1987) During the past decade, the Department of Water has further developed the principle of retaining or detaining 1-in-1 year average recurrence interval (ARI) events within urban catchments.
The study draws from the large dataset associated with the Bartram Road catchment’s environmental management plans, including surface water quality, flow, and groundwater quality and levels collected during the past 16 years. During the 1990s and 2000s, land use in the Bartram Road catchment changed from mostly agriculture and lifestyle blocks to medium-density urban residential blocks (~600 m2).
