Description
Compare remaining keyhole-bed radial depth with a supplied reach.
Garden-resource planning uses supplied geometry, material stocks, visit counts and accounting boundaries. Water elevation difference gives nominal head before losses, while a screened reject fraction uses the screened total. Local arithmetic does not establish plant compatibility, suitable animal care, drainage performance or a safe structural design.
Compare remaining keyhole-bed radial depth with a supplied reach.
When to use this tool
Use Key Hole BED Reach Radius when you already have outerRadius, accessNotchDepth, suppliedReach and need to compare remaining keyhole-bed radial depth with a supplied reach.
How to use the tool and how it works
- Enter outerRadius, accessNotchDepth, suppliedReach. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read remainingRadialDepth, reachMargin. Use the output convention below.
Require nonnegative radius/reach and notchDepth in [0,radius]; remaining=radius-notch, margin=reach-remaining.1
| Input field | Meaning and units | Accepted input |

| suppliedReach | Supplied Reach | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| remainingRadialDepth | Remaining Radial Depth | Required. Finite number. |
| reachMargin | Reach Margin | Required. Finite number. |

}Limitations and assumptions
- Uses simplified radial geometry and a supplied reach; actual access, ergonomics and planting design are not assessed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- 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. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Measure actual site geometry and reconcile resource stocks, transfers and observation periods. For water delivery, account for the complete hydraulic path and losses; nominal head and local garden margins remain preliminary bookkeeping or geometry.
