Agriculture Terrace Spacing Calculator
Actual varying slope segments and independently permitted vertical terrace intervals, horizontal spacing only, no empirical erosion/storage safety. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Terrace spacing relates a chosen vertical interval to measured local slope.
Terrace spacing relates a chosen vertical interval to measured local slope.1
The calculation does not select an erosion-control design or validate a permitted interval. Use Agriculture Terrace Spacing Calculator to evaluate the supplied inputs under the model explained below.
When to use Agriculture Terrace Spacing Calculator
Use Agriculture Terrace Spacing Calculator to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Agriculture Terrace Spacing Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed slope segment rise m, Observed slope segment run m, Caller permitted terrace vertical intervals m using the field table and validation rules below, then run the tool.
- Read Caller horizontal terrace spacings m; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedSlopeSegmentRiseM | Observed slope segment rise m | array of number | Required; constraints below |
| observedSlopeSegmentRunM | Observed slope segment run m | array of number | Required; constraints below |
| callerPermittedTerraceVerticalIntervalsM | Caller permitted terrace vertical intervals m | array of number | Required; constraints below |
Enter nonempty aligned positive measured rises, horizontal runs and caller permitted vertical intervals in m. For each segment return interval×run/rise as horizontal spacing in m. No vertical interval, runoff criterion, contour layout or construction approval is selected.
horizontalSpacingM[i]=callerVerticalIntervalM[i]×runM[i]/riseM[i] Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| callerHorizontalTerraceSpacingsM | Caller horizontal terrace spacings m | array of number |

}Limitations and assumptions
The calculation does not select an erosion-control design or validate a permitted interval. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
