Spillway Discharge Calculator

Calculate discharge over ogee (overflow) and broad-crested spillways using standard weir equations and USBR design coefficients.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate discharge over ogee (overflow) and broad-crested spillways using standard weir equations and USBR design coefficients

Each component has a specific meaning:

  • Standard weir equations — The standard weir equations recorded for the patient or scenario being assessed.
  • USBR design coefficients — The usbr design coefficients recorded for the patient or scenario being assessed.

Note: Interpret the spillway discharge result against the clinical thresholds and context described above.

How to Use

Enter the standard weir equations, USBR design coefficients for the patient or scenario you are assessing. Calculate discharge over ogee (overflow) and broad-crested spillways using standard weir equations and USBR design coefficients. Use the spillway discharge result to inform your clinical assessment.
