Australia is in the midst of an energy transition.  The move to Electrify Everything is underway.  This revolution requires a myriad of activities in various areas.  This stream focuses on multiple ways infrastructure networks, systems and services contribute to urban renewal, regional development, better liveability and enhanced productivity. Smart data analytics, resource assessment and forecasting, digital twins, real-time modelling and complex network optimisation are becoming essential instruments for planning, managing, protecting and upgrading these systems. The stream can include submissions covering forecasting of renewables, energy efficient building design, microgrid design, precinct infrastructure, and related topics.

F. Environment and ecology

Stream Leaders: Stefan Reis and Shawn Laffan

Modelling, simulation and software systems play a pivotal role in our understanding of environmental and ecological systems. Complex interactions and relationships require environmental modelling and software tools to underpin and improve decision making in policy and regulatory contexts. Advances in data science, machine learning and approaches to harness big data are key to tackle vast challenges of environmental degradation and global climate change. We encourage the submission of sessions which focus on the development of generic frameworks and integration of models across issues, scales, disciplines and stakeholders. The stream accommodated sessions spanning a scope from advances in modelling, software and simulation, the development and use of advanced software tools, interdisciplinary and transdisciplinary environmental modelling, the integration of models and software tools across issues, scales, disciplines and stakeholders, to the application of novel data science concepts in decision support.

K. Hydroclimate

Stream Leaders: Yongqiang Zhang and Conrad Wasko

This stream focuses on the research fields between climate and hydrology. With continuous climate change in the past several decades and the foreseeable future, our understanding of the hydroclimate continues to evolve, and the complexity in forecasting, predicting, simulating, or attributing change, means many processes, and their interactions, remain not completely understood. However, new data sets, statistical tools, modelling techniques, and advances in computing are all providing us opportunities to improve the understanding of the hydroclimate. Proposals were invited from a wide variety of disciplines that analyse and model all aspects of the hydroclimate, from rainfall, to streamflow, evapotranspiration, groundwater, temperature, and their related hazards. Proposals were encouraged that aimed to improve our process understanding, untangle uncertainties, and attribute changes across all time and spatial scales in the hydroclimate.

L. Water quality

Stream Leaders: Andrew Western, Danlu Guo and Anna Lintern

Poor water quality has social, economic and environmental consequences, and maintaining good water quality is key to sustaining human life. While we still need to understand fundamental water quality processes, we increasingly have a need to model new and emerging water treatment systems, emerging chemicals, the impacts of climate change and land and water management on water quality, and interactions between socio-economic systems and water quality. Proposals were invited to focus on monitoring, modelling and analyses of all aspects of water quality across all environments including natural, agricultural, urban, peri-urban catchments, as well as rivers, groundwater, lakes, estuaries and other receiving waters.

Stream Leaders: Melanie Ayre and Simon Dunstall

The Operations Research (OR) stream covered high-quality contributions from across the broad spectrum of OR methods, techniques and applications in academia, defence and industry. Techniques may include (but are not limited to) mixed integer-linear programming, constraint programming, metaheuristics, and modelling and simulation through to more recent approaches in matheuristics, artificial intelligence (AI), machine learning (ML) and data sciences (DS). Applications areas may include (but are not limited to) emergency management and natural hazards, defence, transport, logistics, mining, agriculture and healthcare. Collaboration was encouraged between academia and industry in both session proposals and paper submissions.
