A simple flow-metering device for use in flood irrigation experiments

Abstract

A flow-metering device has been developed for the measurement of rate of flow of water for flows up to one cubic foot per second from surface irrigation channels on to flood-irrigated land with a head difference less than six inches. Approach flow conditions do not affect the relation between rate of flow and head loss across the meter within the degree of accuracy required. A simple version of this meter is cheap to construct and gives adequate accuracy.
