List of figures
Figure 1 . Rainfall deciles during the Millennium Drought (1997 to 2009) in eastern Australia (a), and the river networks of the Wee Jasper catchment (b) in New South Wales, Australia. The rainfall deciles subplot (a) shows that mean annual precipitation in the region of the Wee Jasper catchment during the Millennium Drought ranged from very much below average to lowest on record. Subplot (a) was accessed from the Bureau of Meteorology of Australia (http://www.bom.gov.au). The green open circle indicates the location of the Wee Jasper catchment.
Figure 2 . Annual rainfall, runoff, and temperature anomalies for the Wee Jasper catchment, New South Wales, Australia (expressed as a percentage of mean annual rainfall, runoff, and temperature over the period of 1970-2014). The bars in cyan and red indicate annual rainfall, runoff, and temperature values larger and lower, respectively, than the mean values. The solid black lines are the three-year moving averages.
Figure 3 . Linear relationship between annual rainfall and runoff in the Wee Jasper catchment, New South Wales, Australia transformed by the Box-Cox method during two different periods,i.e ., before (red line) and after (cyan line) 1997.
Figure 4 . Observed (red line) and simulated (cyan line) monthly runoff from 1970 to 2014 in the Wee Jasper catchment, New South Wales, Australia.
Figure 5 . Annual anomalies of the estimated values of parameters (a) SC (catchment active water storage capacity and (b)C (constant reflecting catchment evapotranspiration dynamics) of the two-parameter monthly water balance model expressed as a percentage of the mean annual value of SC or C over the period of 1970-2014. The bars in cyan and red indicate annual values of SC or C that are larger and lower, respectively, than the mean annual values. The solid black lines are the three-year moving averages of annual anomalies.
Figure 6 . Estimated monthly values of parameters SC and C from 1970 to 2014. The grey ribbon and the blue line represent the 5.0%–95.0% range and mean, respectively, of estimated monthly values of an ensemble of 100 model runs. The red dashed line represents the mean values of SC and Cfor the periods before and after the step changes identified by the Pettitt’s test.
