As man’s need to use and measure water has increased, a number of different and varied methods have been developed to measure the flow of water in open channels. Open channels are those natural and man-made structures through which water flows with a free surface.
Examples of such structures include streams, rivers, irrigation ditches, canals, partially full pipes, and water conveyance flumes.
Some of the more common methods currently in use to measure open channel flows are:
- Timed Gravimetric
- Tracer-Dilution
- Area-Velocity
- Manning’s Equation / (Gauckler-Manning-Strickler Formula)
- Hydraulic Structures (Flumes & Weirs)
