The conference brought together a broad spectrum of scientists studying mathematical modelling, simulation, statistical, engineering, spatial and computer science with more than 700 papers being submitted. Some key themes were spatio-temporal verification of numerical predictions, decision support systems for complex water resource systems, economic modelling, global change and natural hazards, and effective use of modelling to inform and support water management decisions.

In the session dedicated to water resources, specifically measuring and modelling of interaction between surface water and groundwater, Dr Beatrice Giambastiani presented a multidimensional spatial analysis of hydrograph data for mapping river and aquifer interactions. This 3D time and space analysis of groundwater head change enables the 3D mapping of hydraulic pathways through complex sedimentary aquifer system in the Namoi Catchment (NSW).

Mr Conrad Wasko also presented in a session dedicated to modelling of weather and climate extremes and their impact in a changing climate. His paper, entitled “Assessing the impact of the 11-year solar cycle on drought in Australia”, presented the result of several model simulations showing that the cycle has a significant impact on the long-term persistence of climatic trends in an already very variable climate such as Australia.

The conference included a ‘break-out’ on Wednesday afternoon where conference delegates were invited to sample some of the more scenic parts of Cairns and its surrounds. Along with many other conference delegates, Beatrice and Conrad visited Green Island, just off the coast of Cairns for an afternoon of snorkelling.
