Description
Calculate available=stored-unusable+anticipatedRain and daysCover=available/dailyUse.
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 available=stored-unusable+anticipatedRain and daysCover=available/dailyUse.
When to use this tool
Use Rain Barrel Irrigation Day Budget Term 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 stored, unusable, dailyUse, anticipatedRain. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read available, daysCover. Use the output convention below.
Calculate available=stored-unusable+anticipatedRain and daysCover=available/dailyUse. Require positive daily use, stored at least unusable, and nonnegative unusable and anticipated rain volumes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| stored | Stored | Required. Finite number. |
| unusable | Unusable | Required. Finite number; minimum 0. |
| dailyUse | Daily Use | Required. Finite number; strictly above 0. |
| anticipatedRain | Anticipated Rain | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| available | Available | Required. Finite number. |
| daysCover | Days Cover | Required. Finite number. |

}Limitations and assumptions
- Anticipated rain is treated as usable supply without a capacity cap. The result assumes constant consumption and does not forecast rainfall or verify water quality or storage safety.
- 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.
