WORKSHOPS
Half-day workshops will be held on Friday 17th July 2009. Invitations are sought for workshop sessions. Contact Roger Braddock (R.Braddock@griffith.edu.au) and Bob Anderssen (Bob.Anderssen@csiro.au) with a description of the workshop.
W1. Surface water groundwater interaction workshopOrganisers: David Rassam, CSIRO Brisbane Lab, ph:07 3214 2724 david.rassam@csiro.au
Ian Jolly, CSIRO Adelaide Lab, ph:08 8303 8706 ian.jolly@csiro.au (away until January)
The workshop is designed to summarise the current state of knowledge on modelling surfacewater-groundwater interaction (covering conceptual and analytical approaches) in relation to connected river systems where double accounting of water is a specific issue. Examples highlighting the Australian experience to date will be presented, drawing on the results of a number of recent eWater CRC, CSIRO and other projects. This workshop aims to present the concepts and theory behind the modelling of surfacewater-groundwater interaction, and to illustrate the development of appropriate modelling approaches. The workshop will alternate between lectures and computer-based exercises to illustrate the key modelling methods. Attendees will gain a good understanding of the range of available modelling approaches and how data availability and the spatial and temporal scales of the particular management or policy issue in question determines the most appropriate approach.

W2. Expert Elicitation
Organisers:Dr Samantha Low Choy (s.lowchoy@qut.edu.au)
Prof Kerrie Mengersen (k.mengersen@qut.edu.au)
Expert knowledge provides valuable input to modelling in a wide range of ways. Expert elicitation is a multidisciplinary field that addresses the rigorous and repeatable process of quantifying expert knowledge for input into models. In the field of Bayesian statistical modelling, elicitation formally quantifies expert knowledge into prior distributions. In risk assessments and reliability analysis, expert knowledge is quantified as parameters describing probabilities of events. At a more fundamental level, researchers in cognitive psychology have been investigating the way in which non-mathematicians conceptualize probabilities and probabilistic statements. This workshop builds on the session on Expert Elicitation, in the conference.
We propose the following format for the workshop:

We propose the following format for the workshop:
- Initially speakers (both invited and contributions from the floor) will be asked to provide short presentations addressing some current issues facing Expert Elicitation, esp. those that would benefit from a cross-disciplinary approach.
- The panel of invited speakers will then take questions from the floor.
- The session organizers, in consultation with the panel, will propose some workshop topics.
- Workshop participants will then be invited to split into discussion groups to address the topic of interest to them.
- The workshop will conclude with feedback from one spokesperson from each group to all participants.
W3. Modelling and Simulation for Defence SystemsOrganiser: Dr Dushy Tissainayagam, University of Adelaide (dushy.tissainayagam@adelaide.edu.au)
This introductory workshop covers the basics on modelling and simulation in a defence context. It is aimed at those who develop or use models and simulations for defence related research, analysis or training. The workshop includes step-by-step examples so that workshop attendees will have an opportunity to appreciate the iterative nature of modelling and simulation tasks.
The workshop will cover the following five topics. In addition, worked examples involving a Helicopter Simulation will be discussed under each topic. The Helicopter Simulation is a teaching aid that allows workshop attendees to put their simulation based decision-making skills into practice.

- Introduction and Nomenclature: Defining the terms and phrases, such as system, model, simulation, emulation, etc and what they mean in a defence context; viewing defence systems as physical systems versus viewing them as organic systems.
- Taxonomy: Explaining live, virtual and constructive simulations and their respective usage in defence; the advantages and disadvantages of doing modelling and simulation in each domain.
- Tools and Techniques: Commercially available modelling and simulation tools; their functionality and limitations; developing in-house tools versus buying off-the-shelf software; choosing the right tools; how and when to use different tools; HLA, DIS and TENA; their functionality and limitations; emerging standards.
- Fidelity and Accuracy: Differences between fidelity and accuracy in models; how to determine the levels of fidelity and accuracy; the S-graph; trading off fidelity for accuracy and vice versa.
- Lessons Learnt: Habits of highly effective modelling and simulation personnel; common mistakes made when developing models; the three laws of modelling and simulation.
