Abstract
At the second National Water Planners Forum, Mark Hampstead and Claudia Baldwin introduced the 'Mystic River Scenario': an innovative role-play scenario designed to simulate a realistic context for consideration of key water planning issues including climate change and risk assessment. The information used to design the Mythic River scenario is derived from multiple CSIRO sustainability studies, and is presented using a similar strcuture, based on the assumption that this type of information on future inflows, land use changes and projected water demand will be similar to the type of information that planners do and will use in developing water management regimes.
