The recent flooding in Queensland affected rural areas, mines, towns and cities including the state capital. Tracking such an event on a day-by day basis raises practical and theoretical issues. While this year’s floods captured world headlines, there is a major flooding event in Queensland about every second year. There are obvious costs resulting from serious flooding, and some can be reduced significantly if the public are reliably informed (whether to evacuate, what property to save, where to evacuate to, what route to take, where to store property). There are also indirect costs to be reduced by the dissemination of reliable information. For example, losses to the tourist industry caused by exaggerated reporting. The paper explores strategies to provide advice to the public by presenting: available raw imagery leaving users to make an interpretation, processed data with information for probable inundation, processed data overlaid with a quality mask indicating reliability, corrected data using a variety of sources, or combination of existing numerical flood models with topographic information to predict flood extent. The paper addresses various sensor products that can be used, their combination with flood modelling techniques, a historical record of inundations, direct measurements (river gauges, rainfall measurements, sensor webs etc.) and more diffuse inputs (crowd sourcing) to supply the best possible decision support information to the public.
