The purpose of a Parshall flume is to measure the flow of water in an open channel (or non-pressurized pipe). This water can be from a variety of sources, including: rivers, streams, canals, channels, field runoff, mine discharge, dam seepage, springs, wastewater, and industrial discharges.
What is the purpose of a flume?
Flumes are specially shaped, engineered structures used to measure the flow of water in open channels. Flumes are static in nature - having no moving parts - and develop a relationship between the water level in the flume and the flow rate by restricting the flow of water in various ways.
How do flumes measure flow?
A Parshall Flume is a fixed, hydraulic structure used to measure water flow in an open channel or non-full pipe. The flume accelerates flow by both a contraction of the parallel sidewalls and a drop in the throat's floor elevation.
