Notes:Explanation and equation(s)

1. Raw capacitance value obtained (10 min interval)
2. Raw value converted to calibrated mm value using calibration equation
3. Daily averages calculated
4. Velocity value for particular height in mm calculated using stage-velocity relation
y = -1E-04x2 + 0.0123x + 0.0406 Where y is velocity, x is height/stage
5. Daily flow volume (m^3) = Height (m) * Velocity (m/s) * channel length (fixed:0.67m) * 3600 seconds * 24 hours
*Correction factor applied to STP sensor levels of -3.1 cm as there was instrument error [tilt in pipe/sensor]
