Mean annual deep drainage (mm / y) in the present day scenario

Definition:Mean annual deep drainage. This is the amount of water draining below the root zone.Interpretation:Significant deep drainage is confined to irrigation areas, and wet areas where rainfall exceeds potential evaporation at least for some months of the year: the southeast (including Tasmania), over the eastern ranges and in the north.Deep drainage has a broadly similar pattern to runoff, though with added variability through the influence of soil texture.Notes: rule-based method is used to estimate the rate of deep drainage on the basis of soil texture, with modification to account for cultivation and irrigation.For this quantity, results are given for the aBASEa (pre-1788) and aAGRICa (present day) conditions.The aAGRICa case includes current agricultural inputs of water from irrigation.FWLeach.Agric a Mean annual deep drainage (mm y-1) in the aAGRICa (present day) scenarioFWLeach.Base a Mean annual deep drainage (mm y-1) in the aBASEa (pre-1788) scenarioData is in geographics and GDA94.
