Pre-registration is mandatory and while the event is free for Engineers Australia members, non-members entry is $30.


Pre-releasing is a dam operating methodology that involves releasing water prior to an expected flood event to create airspace within the dam. The airspace is created with the aim to capture the first of the floodwaters. The presentation compares flood operating procedures for major gated dams at leading dam owners in the USA, Canada, and UK, particularly focusing the role of ‘pre-releasing’ during floods.

The millennium drought was broken in the South-Eastern Australia by major floods in December 2010, followed by another significant wet season in March 2012. This period saw major flooding in the cities of Brisbane, Wagga Wagga and parts of Victoria.

Operation of dams during these floods came under heavy media scrutiny. In case of Brisbane a Commission of Inquiry investigated the operations of Wivenhoe Dam. Similarly, a Ministerial review looked at operations of Burrinjuck and Blowering dams in relation to flooding at Wagga Wagga. Victorian Government also commissioned a review of floods in that state.
