Water balance
modelling is commonly required to assess water demand by plants and the
proportion of surface runoff and deep drainage resulting from particular development
or land use scenarios.
Water balance
models are used to produce the following outputs:
|
● |
hydraulic loading (effectively ML/ha/an of
rainfall plus irrigation); |
|
● |
deep drainage (water movement below the root
zone of crops, pastures, forests, parks and gardens); |
|
● |
subsurface interflow and surface runoff; and |
|
● |
nitrogen and phosphorus uptake by plants and
movement offsite with the excess water. |
