Try the starting example
- Starting invert elevation (m)
- 100
- Horizontal segment lengths (m)
- 10,20,5
- Segment gradients (percent)
- 1,2,1.5
- Invert elevations after each segment (JSON)
- [99.9,99.5,99.425]
- Total fall (m)
- 0.575
Try another scenario
- Starting invert elevation (m)
- 101
- Horizontal segment lengths (m)
- [10, 20, 5]
- Segment gradients (percent)
- [1, 2, 1.5]
- Invert elevations after each segment (JSON)
- [100.9,100.5,100.425]
- Total fall (m)
- 0.575
Calculation method
Calculation method
Invert elevations after each segment (JSON)
Chain supplied falls sequentially; positive gradient slopes downward.
Total fall (m)
Chain supplied falls sequentially; positive gradient slopes downward.
Symbols and units
- a
- Starting invert elevation (m)
- b
- Horizontal segment lengths (m)
- c
- Segment gradients (percent)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Chain supplied falls sequentially; positive gradient slopes downward. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
