Two major predicted hydrological impacts that may occur due to human use of sub-catchments of the Murray-Darling Basin include extreme flood and drought conditions. These two hydrological events may occur within the Basin as a result to inceased dry and wetland conditions caused by future climate changes (CSIRO and the Bureau of Meteorology 2011). As demonstrated in the graph, if these hydrological conditions where to occur to the basin an increase in surface water avaliability will become present due to increased ocean water temperatures and the occurance of La Nina events within Australia (Connel, D & Grafton, R 2011 (b)). These predicted hydrological factors have major implications on Australias biophysical, economic, social and cultural
