Planning estimate
Sharp-crested freely discharging V-notch; theta is full notch angle in degrees, 0 < theta < 180. Real discharge coefficients and effective head depend on geometry, angle, approach, submergence and calibration. High-angle predictions can lie outside validated ranges (for example Kindsvater-Shen 25–100 degrees). Method: Inverse V-notch angle theta=2 atan[Q/((8/15) Cd sqrt(2g) H^(5/2))] in degrees. Angle accuracy depends on empirical Cd calibration. Default inputs: Q=0.15 m³/s, Cd=0.6, H=0.25 m.
