Abstract

This chapter describes the development of an improved sub-catchment runoff modeling technique for urban catchments to help overcome parameter scaling and problems caused by process lumping inherent in many existing schemes. The development is based on five years of detailed monitoring of a typical urban catchment in Canberra, Australia utilising nested rainfall and flow gauges to characterise the accumulation of runoff throughout the catchment during a wide range of storm events. The gauging network provided data to interpret allotment scaled process units and their accumulation throughout the 90-hectare catchment. The detailed rainfall/runoff data led to a modified modeling approach that incorporated allotment scaled process definition and the means to cumulate these to any size catchment. Independent testing of the procedure was carried out on a separate catchment in Sydney. The approach also provided the means to further test different allotment scale drainage provisions and their effect at different catchment scales
