    A drip irrigation system is easy to Drip irrigation is the slow and precise delivery of water to chosen plantings. It uses flexible polyethylene tubing with devices for dripping water (emitters) and low-volume sprays. The systems are easy to install, require no trenching, and the only tools needed are pruning shears and a punch. Drip File Size: 2MB.

Third Edition, third edition Edition. by Reclamation Bureau (U.S.) (Producer) ISBN Water Measurement Manual This revised manual has three principal purposes. The first is to provide water users and districts guidance in selecting, managing, inspecting, andmaintaining their water measurement devices.

The second is to describe the standard methods and devices commonly used to measure irrigationwater. Water measurement manual: a manual pertaining to measurement of water for irrigation projects: a Reclamation manual specialist supplement.

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 + % of the actual amount. PartChapter 9 - Water Measurement Manual (current version of the Bureau of Reclamation's Water measurement Manaual) PDF Electronic Version.

After turning off the sprinkler, use a ruler to measure the depth of the water collected in your cans. If it's 1/4 inch, you need to run the sprinkler twice as long, or 30 minutes, to spread 1/2.

Devices Used for Measuring Irrigation Water Several devices are commonly used for measuring irrigation water.

They grouped into four categories 1) Volumetric Measures 2) Velocity-Area Methods a) Float Method b) Water Meters 3) Measuring Structures a) Orifices b) Weirs c) Flumes 4) Tracer Methods 1) Volumetric methods (Using a container) [ ].

The Parshall flume is a fixed hydraulic structure used to measure the flow of sub-critical waters in open channels. Although originally developed to measure irrigation / water rights flow, the use of the flume has been expanded and now includes: •Cooling water discharge.

•Dam seepage. •Industrial effluent. applying irrigation water to the land. In surface irrigation the soil is the reservoir from which the plants draw the water they need. The soil also con- veys and distributes the water over the field. In sprinkler irrigation the water is conveyed above the field in pipes, and the soil acts as a storage reservoir.

In subirrigation the water flows. Manual irrigation methods are appropriate for small-scale farming or backyard gardening irrigation in dry and arid climates where water is scarce. All the different designs reduce water evaporation.
