Calculation method
Calculation method
Flow/exceedance-percent pairs (JSON)
Sort valid observations descending and use Weibull exceedance rank m/(n+1); missing days must be removed explicitly.
Median observed flow (m³/s)
Sort valid observations descending and use Weibull exceedance rank m/(n+1); missing days must be removed explicitly.
Symbols and units
- a
- Nonmissing daily flows (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; Sort valid observations descending and use Weibull exceedance rank m/(n+1); missing days must be removed explicitly. 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.
