Water Balance Components
The water balance components can be grouped into components corresponding to zones in a vertical cross-section in the soil forming reservoirs with inflow, outflow and storage of water:
- the surface reservoir (S)
- the root zone or unsaturated (vadose zone) (R) with mainly vertical flows
- the aquifer (Q) with mainly horizontal flows
- a transition zone (T) in which vertical and horizontal flows are converted
The general water balance reads:
- inflow = outflow + change of storage
and it is applicable to each of the reservoirs or a combination thereof.
In the following balances it is assumed that the water table is inside the transition zone.

Famous quotes containing the words water, balance and/or components:
“The real antichrist is he who turns the wine of an original idea into the water of mediocrity.”
—Eric Hoffer (1902–1983)
““... To say of one mask it is like,
To say of another it is like,
To know that the balance does not quite rest,
That the mask is strange, however like.””
—Wallace Stevens (1879–1955)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
