and irrigation water requirement information needed to plan, design, evalu-ate, and manage irrigation systems. Irrigation Guide, Part , is a new handbook to the family of references in the NRCS, National Engineering Handbook series. It is written for NRCS employees who provide technical assistance to the water user with con-. the measurement of irrigation deliveries to farms. Because of the growing need for accurate measurement of irrigation supplies, the Parshall measuring flume is now used extensively. This practical measuring device, as described in this bulletin, is made in sizes from 3 inches to 8 feet. Its capacity of flow ranges from less than second-foot Cited by: 6.
Sprinkler irrigation is similar to natural rainfall. Water is pumped through a pipe system and then sprayed onto the crops through rotating sprinkler heads. Figure 5 Sprinkler irrigation Drip Irrigation With drip irrigation, water is conveyed under pressure through a pipe system to the fields, where it dripsFile Size: 1MB. Evaporation, Evapotranspiration, and Irrigation Water Requirements is a comprehensive reference to estimating the water quantities needed for irrigation of crops based upon the physics of evaporation and evapotranspiration (ET). This new edition of which updates and expands the original, provides improved and standardized methods.
Water application measurement. Having good equipment is one thing; making it work correctly is quite another. Check out how well the irrigation system delivers water. The goal is the same as for fertilizer--every part of the lawn should receive the exact same amount. At each measurement location, record the depth of water using a flow measurement instrument like a wading rod or measuring tape. Measure the velocity. For the purposes of irrigation ditches, there are generally two methods: the “two-point” method and the “six-tenths-depth” method: Two-Point Method. This method records velocity.

GENERAL INFORMATION FOR WATER MEASUREMENT The standard term for rate of flow of water in an irrigation ditch is cubic feet per second (cfs), often called second-feet (sec-ft) or feet of water. A cubic foot per second of water is flowing when a cubic foot volume of water (equal to 1 ft wide, 1 ft long, and 1 ft.
Chapter 4F: Irrigation Water Management Soil-Water-Plant Relationships Effective and efficient irrigation begins with a basic understanding of the relation-ships among soil, water, and plants. Figure 4f-2 illustrates the on-farm hydrologic cycle for irrigated lands, and Table 4f-1 provides definitions of several terms associated with irrigation.

Water Measurement Examples of Alternative Measurement Methods Electricity Records Dedicated to the Pump.
Description: If a pump has a dedicated meter, the electricity used on the meter, in kilowatt hours, can be correlated to a water volume using a pump a dedicated meter is not present or available, a device called a sub-meter can be installed by qualified electrician.
Measuring irrigation flow contributes to better management and scheduling of irrigation events, thus improving profitability. Such measurements are needed to evaluate the performance of an irrigation pumping plant. Irrigation flow measurements also are a tool for quantifying irrigation water use and are useful in evaluating the effects of.• Irrigation water requirements • Planning farm irrigation systems • Measurement of irrigation water • Design of pumping plants • Design criteria and design procedures for surface, sprinkler, and micro irrigation methods and the variety of systems for each method that can be adaptable to meet local crop, water, and site conditions.Alternative Water Sources for Irrigation.
