Impact of ensembles of full volume rain events on the hydrology of Armstrong Creek at Barwon Heads Road near Geelong (circa 2008)

A modern perspective on the hydrology processes of Armstrong Creek and Canadian Creek catchments in regional Victoria

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.

Is zero afflux the question or answer to better flooding outcomes?

Presentation by Peter J Coombes and Andrew Allan at HWRS 2022: Is zero afflux the real challenge or solution for better flood management? It is vitally important to establish science and legally based rules for fair administration of the objectives and exploration of options that respond to flood risks. Otherwise, there will be a substantial administrative burden for marginal benefit. Our professionals and agencies need to be prepared for a different and challenging future, and our methods need to be fit for purpose from a whole of society perspective.
