Formula Definitions

The Landscape Water Budget Calculator works by applying a well-defined formula to the values you enter. Understanding the formula behind the calculation helps you interpret the result and check that your inputs are correct. Below we break down the key components that drive the Landscape Water Budget.

The core formula used by this calculator is:

Result = f(physical quantities, constants, conditions)

Each variable in the formula has a specific meaning:

  • physical quantities — Measured values with units entered into the Landscape Water Budget.
  • constants — Physical or chemical constants (e.g. CODATA values, gas constant, Avogadro's number).
  • conditions — Temperature, pressure, concentration, or environmental state of the system.
  • Result — Computed physical or chemical quantity with associated units.

Note: Compare results with standard reference values or published experimental data.
