The Hydrology and Water Resources Symposium 2022 has been announced with a call for abstracts already out. It is scheduled for 30 November – 1 December 2022. From the Organising Committee:

“Engineers Australia is set to host the 40th iteration of the Hydrology and Water Resources Symposium from 30 November – 1 December 2022, under the theme, ‘the past, the present, the future.’

Join us as we look back at the work and impact of our industry predecessors, discuss current water-related issues and trends, and explore the innovations and technologies that are shaping the future of water engineering. “
