Examples
Try the starting example
- Observation timestamps (hours)
- 0,1,2,3
- Observed discharge (m³/s)
- 2,5,4,2
- Integrated event water volume (m³)
- 39600
Try another scenario
- Observation timestamps (hours)
- [0, 1.1, 2, 3]
- Observed discharge (m³/s)
- [2, 5, 4, 2]
- Integrated event water volume (m³)
- 39240
Calculation method
Calculation method
Integrated event water volume (m³)
Trapezoidal integration of discharge over strictly increasing timestamps; linear variation between observations.
Symbols and units
- a
- Observation timestamps (hours)
- b
- Observed discharge (m³/s)
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; Trapezoidal integration of discharge over strictly increasing timestamps; linear variation between observations. 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.
