Flood Extent Monitoring in Riparian Forests, Australia

Science Center Objects

The results of flood mapping are used as an input to hydrological models in some instances, and in other cases as an independent source used for the calibration of model outcomes.

Hydrological models are actively used as management tools. The cost of satellite images has a direct bearing on how often flood mapping is carried out to support forest management. In the absence of Landsat data, alternative sources (for example, SPOT-5) cost about $3,853 ($4,000 in Australian dollars) for the Barmah-Millewa forests (fig. 1), and the same amount for the Gunbower and Koondrook-Perricoota forests within the Murray Valley riparian systems. The current frequency of monitoring and flood mapping would not be possible without Landsat imagery availability (Kathryn Sheffield and Mohammad Abuzar, Department of Environment and Primary Industries , written commun., 2013).
