| | Summary: |
| | For a b=0.0254 m wide Parshall flume, literature provides the dependence
of flowrate and water depth in the throat within the flowrate range of 0.13-4.38 l/s. Volumetric measurements of flow (flow range 0 – 3 l/s) and water level measurements with ultrasonic transmitter prove that hydrograph can be determined using equation (2) (within accuracy range of -5.36 to +4.99%), or with equations (4) and (5) (within accuracy range of -3.46 to +4.77%) for water temperatures of 11.5-16oC.
