9.4 Runoff to surface water
The volume recognised in the water accounting statements (30,590,000 ML) represents the total volume of runoff into surface water within the Daly region during the 2011–12 year.
Runoff to surface water in the Daly region was estimated using a surface water model of the Daly River catchment developed using the MIKE 11 software by DHI.
The calibration of the MIKE 11 model involved adjusting the model parameters to ensure model outputs matched observed streamflow data in the region adequately. A detailed description of the model calibration process is provided in Knapton et al. (2010).
Assumptions, limitations, caveats and approximations
The runoff estimates were subject to the assumptions of the MIKE 11 model detailed by Knapton et al. (2010).
Derived from modelled data. The uncertainty estimate was not quantified.
