Description
Calculate netAvailable=fresh+recovered-exported-evaporation and reusedShare=recovered/(fresh+recovered).
A farm or garden budget depends on a common area, quantity, observation period, and system boundary. Recovery, exclusions, overlap, and allocation change how a share is calculated. Supplied accounting or geometry terms remain separate from measured crop performance and verified environmental outcomes.
Calculate netAvailable=fresh+recovered-exported-evaporation and reusedShare=recovered/(fresh+recovered).
When to use this tool
Use Irrigation Reuse Water Balance Share when you need a clearly bounded area, material, resource, energy, or allocation term for supplied garden or farm records.
How to use the tool and how it works
- Enter fresh, recovered, exported, evaporation. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read netAvailable, reusedShare. Use the output convention below.
Calculate netAvailable=fresh+recovered-exported-evaporation and reusedShare=recovered/(fresh+recovered). Require nonnegative quantities and positive combined supply.1

}Limitations and assumptions
- NetAvailable can be negative because deductions are not capped. Water amounts must share one boundary and period; usability, treatment, weather, and irrigation suitability are not assessed.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Verify the system boundary, units, and source records before combining this term into a resource or environmental report. Physical design and crop-performance questions require appropriate measurements and a broader model.
