Abstract
This paper reports on a broad-scale assessment of water yield impacts of the 2003 Alpine bushfires, which burnt over 1 million ha across northeastern Victoria and southern NSW, including catchments of a number of key water storages, such as Hume and Dartmouth Dams, and also the Gippsland Lakes. A new model - Bushfire Impact on Streamflow Yield (BISY) - was developed to estimate the change in streamflow. Streamflow response curves were derived for the different species, which were based upon recorded streamflows and transposed based upon the mean annual rainfall. The impact on streamflow was estimated for 12 catchments ranging in size from approximately 500 to 10,000 km2. For each catchment a..
