Modelled wet years (1973 - 1975) average annual diffuse recharge (mm/yr)

dataset: ENSYM_RECHARGE100_WET
Modelled wet years (1973 - 1975) average annual diffuse recharge (mm/yr) as calculated using the Ensym model. Includes rainfall recharge and irrigation recharge however excludes river/stream/channel/reservoir leakage. Ensym estimates daily spatial recharge by solving for physical processes using analytical solutions and empirical equations. Water entering the soil profile is initially determined by subtracting the calculated surface runoff from the total daily precipitation and irrigation. Once in the soil profile, water can be removed by evapotranspiration, lateral flow and downward movement if soil capacity is exceeded. Water fills up lower soil layers until it exits the soil profile and becomes drainage. Drainage is then partioned into sub surface lateral flow and recharge.

Attribute Quality
Estimates of recharge vary in accuracy based on input datasets. Variability in soil mapping adds the highest uncertainty in recharge estimates. 
Positional Accuracy
Precision: 10 - 100m Determination: Based on the scale of input datasets
