Irrigation is the largest water use in. Kansas. There are about 3 million irri- gated acres, of which nearly 95 percent is supplied by groundwater. Unfortu- nately, groundwater levels have been declining in most of the major irrigated areas due to overpumping, causing con- cern over the long term water availabil- ity from these
Description. The volumetric measurement of irrigation water use provides the water user with information needed to assess the performance of an irrigation system and better manage an irrigated crop. There are numerous types of volumetric measurement systems or methods that can be used to either directly measure the
continued demand for the Water Measurement Manual are responsible for initiating this revision. The first edition of the Water Measurement Manual (1953) had a distribution of 11,000 copies and was compiled from the Bureau of Reclamation (Reclamation) publication Manual for. Measurement of Irrigation Water (1946).
One of the major problems in surface irrigation system is the low efficiency of irrigation water. A measure that is essential for reducing waste and ensuring more efficient use among farmers is metering the volumes of water supplied and charge for it. There is a wise saying, “You cannot manage something if you can not.
conserving water without compromising crop yields. First and foremost, all irriga- tors need to know their system's net water application rate, measured in inches per hour or inches per irrigation. Not covered in this publication are some equally basic skills essential to irrigation management. All irrigators should know general
Measurement accuracy is the difference between the true flow and the flow measured with a meter. The measured flow should be as close as possible to the actual amount of water flowing in the pipe. Most irrigation meters should have an accuracy of + 2.0% of the actual amount.
Irrigation water management begins with knowing how much water is available for irrigation. Fact Sheet 1501, dis- cusses water measurement units and useful factors for convert- ing from one measurement unit to another. The purpose of this fact sheet is to discuss a few basic methods of water measure- ment. Methods of

Measuring device possible functions: • Measure cumulative flow volume. • Memorise and continuously display cumulative flow volume. • Measure instantaneous flow rate (Q). • Display instantaneous flow rate (Q)continuously. • Memorise history of instantaneous flow rate. • Measure depth of flow (h). • Measure flow velocity (v).
