Correct path to use flumes in water resources management

Abstract The hydraulic characteristics of the flow are measured using tools such as flumes, in design and evaluation furrow irrigation systems. Proper use these tools, their immersion while working, is one important executive points this field; study, trapezoidal flumes used to measure intensity input output irrigation. proper method installing was investigated article. For purpose, during 60 operations, results showed that order create free conditions not affect downstream upstream current, well increasing accuracy measurements, addition all directions, flume should be installed at a height least about 4 cm above bed; according percentage installation from bed observed standard (less than 70% immersion) reduce measurement error different depths water entering flume. also for ensuring or more bed, provided ridges strengthened end inflow furrow. current floor along prevent passage after outflow flume, deeper terms flow. Observance obtained study systems prevents errors consequently increases
