Description
Subtract nonnegative drainageDepth and freeboard from totalDepth, requiring a nonnegative remainder as soilDepth.
Simple site geometry approximates an area, section, or volume using ideal shapes. Coherent length units and the distinction between signed and unsigned quantities determine the result's meaning.
Subtract nonnegative drainageDepth and freeboard from totalDepth, requiring a nonnegative remainder as soilDepth.
When to use this tool
Use Planter Drainage Layer Net Depth when you need one transparent landscape geometry component.
How to use the tool and how it works
- Enter totalDepth, drainageDepth, freeboard. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read soilDepth. Use the output convention below.

}Limitations and assumptions
- Use matching length units; no root-zone adequacy, structural load, or drainage performance is 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
Use a surveyed terrain or construction model when irregular shapes, settlement, drainage, and structural performance matter.
