Standard metergates, weirs and flumes are common devices installed in open channels and irrigation ditches to measure water flow.

The present study examines the integrating float method and defines the parameters affecting the acceleration of floating spheres in flowing water.

The velocity distribution in a channel section can be measured either by a pitot tube or a currentmeter. The typical patterns of velocity distribution.

Two very common methods of measuring the flow of water in an open channel are considered: venturi flumes and weirs. Initially, the basic parameters of the ...

This standard provides general guidelines for the selection of a suitable method for measurements of liquid flow in open channels, with specific provisions.

Critical flow occurs when the velocity of water is the same as the speed at which disturbances of the free surface will move through shallow water.
