Description
Divide signed verticalDrop by positive horizontalLength for signedSlope.
Flow calculations relate volume, time, cross-section, velocity, and supplied model parameters. A local ratio or contribution does not by itself solve a complete hydraulic system.
Divide signed verticalDrop by positive horizontalLength for signedSlope.
When to use this tool
Use Channel Drop Length Ratio when you need one explicit flow component with coherent units and references.
How to use the tool and how it works
- Enter verticalDrop, horizontalLength. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedSlope. Use the output convention below.

| verticalDrop | Vertical Drop | Required. Finite number. |
| horizontalLength | Horizontal Length | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedSlope | Signed Slope | Required. Finite number. |

}Limitations and assumptions
- Both lengths share units and a positive drop follows the caller's elevation order; this is rise/run arithmetic rather than an angle, percent grade, or hydraulic calculation.
- 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 surveyed geometry, appropriate calibration, and a complete hydraulic model for operational or design decisions.
