International Association of Hydrogeologists Australia


A reflection of 30 years of searching for and managing this important groundwater resource

Seth will be talking about his experience in the exploration and managing of groundwater resources associated with palaeochannel aquifers in Western Australia. It is aimed at junior to intermediate hydrogeologists to highlight an interesting aquifer system that can be very frustrating to locate but has supported the mining industry in the Goldfields for the past 30 years. The talk will provide a history of palaeochannels in Western Australia, key references and the longevity of this important groundwater resource that is positioned in the most arid parts of the State.
