There is often considerable disagreement about the critical hydrological parameters and resultant hydrological, hydraulic and ecological responses of ungauged urban catchments.
New methods from the latest version of Australian Rainfall and Runoff (ARR2016) were used to analyse emerging urban catchments. This included Regional Flood Frequency Estimation, rainfall runoff observations from nearby gauged catchments and ensembles of full volume rain events.
These processes were be used to transfer hydrology parameters from nearby gauged catchments to urban catchments with similar natural characteristics. This process allows the determination of a flood frequency analysis of the nearby urban catchment as demonstrated for Armstrong Creek near Geelong and Canadian Creek near Ballarat.
