Measuring Flow in a Canal That Backs Up
Where a gate backs water up, water level alone can't give canal flow. An index-velocity station can: its meter reads speed through the depth, around the clock.

Measuring canal flow
A three-part series on canal stations that measure water speed as well as water level, and where the Lodestar fits. A plain-language glossary explains the trade terms.
Why the Lodestar Index Velocity Meter Uses One Beam
Why one narrow beam suits a canal gaging station: on the bed or at the surface it reads speed through the depth, works in shallow water and can sit above silt.
Bed, Surface or Universal: Three Ways to Mount a Lodestar ADVM
Mounting an index velocity meter (ADVM) in a canal: when to choose a bed, surface or universal Lodestar, by silt, access and reverse flow.
Plain-Language Glossary: Measuring Canal Flow
Plain-language definitions of the terms used in HyFlow's series on measuring canal flow with a fixed acoustic Doppler velocity meter.
