A Co-Knowledge Approach to Assessing Inland Flood Risk in a Changing Climate
A joint Queensland Government and Local Government Association of Queensland project was established to identify an updated and effective policy approach to managing inland flood risks in a changing climate as prescribed in the Queensland State Planning Policy 1/03 Mitigating the Adverse Impacts of Flood, Bushfire and Landslide (SPP 1/03). SPP 1/03 provides guidance to Local Government authorities on undertaking flood risk assessment for setting their planning constraints. The current policy indicates that jurisdictions should take into account climate change when considering their flood risk, but provides no guidance on how to do this. The Engineers Australia publication, Australian Rainfall and Runoff (AR&R) (Pilgrim, 1998) provides the technical guidance for undertaking flood studies. This publication is currently being reviewed to take into account climate change; however the revision is not due to be completed until at least 2012. Using a case study approach based on a central Queensland town, this project has been established to include: . A review of relevant science and flood models with a view to developing an improved methodology for assessing inland flood risk in a changing climate; . A review of the current policy approach to flood risk management; . Assessment of alternative policy approaches to flood risk management and the adaptability / effectiveness of current policy measures to future flood events under a changing climate; and . Recommendations on specific policy options for improved flood risk management in the case study area, and identify general policy options for consideration as part of the forthcoming review of SPP 1/03. This paper primarily covers the methodology and preliminary outcomes of the review of the relevant science and flood models, as well as providing some context with respect to the study area and the potential implications of updating policy approaches to flood risk management. This co-knowledge approach is designed to ensure that the science and policy are being directly informed by each other.
