Dept. of Agriculture, The commonly used irrigation methods are surface, sprinkler, and drip irrigation. Each method has its own merits and demerits, depending on the soil, topography, type of crops, climate, water availability and quality, and investment, which are the guiding factors for selecting an adequate irrigation method.
Irrigation systems should apply the amount of water needed by the crop in a timely manner without waste or damage to soil, water, air, plant, and animal re- sources.
This includes, but is not limited to, offsite water and air quality and desired impacts on plant and animal (including fish and wildlife) diversity.

Evaluating Irrigation System Uniformity. Standards and Methods for Evaluation of Irrigation System Uniformity. • Two commonly accepted standards or methods are available as guidelines for performing evaluations of Irrigation System Uniformity.
For monitoring and evaluation to succeed, irrigation managers need to de velop a new evaluative mind-set that enables them to appraise their projects' per formance objectively, reflect on what has been learned for future use, and adjust policies on the basis of that knowledge whenever Size: 1MB.

A brief review of the relevant performance parameters, factors which affect these parameters and current evaluation methodologies is given. A common and very simple technique for manual irrigation is for instance the use of watering cans as it can be found in peri-urban agriculture around large cities in some African countries.
A more sophisticated and very water-efficient type of manual irrigation system is small-scale drip irrigation with buckets (see also drip irrigation). 8 DRIP IRRIGATION HANDBOOK System head DRIP IRRIGATION SYSTEM OVERVIEW A drip irrigation system comprises many components, each one of them playing an important part in the operation of the system.
The aim of this chapter is to provide an overview of the drip irrigation system components, their functions and properties. Water Supply Systems. and Evaluation Methods He has authored many book and articles including.

More sophisticated methods of water application are used in larger irrigation systems. There are three basic methods: surface irrigation, sprinkler irrigation and drip irrigation. Surface irrigation. Surface irrigation is the application of water to the fields at ground level.
Selection of Irrigation Methods for Agriculture identifies various types of irrigation methods and provides an extensive discussion of the elements that guide the selection of a method for a particular application.
Methods include surface irrigation, drip/macro irrigation, sprinkler irrigation. The International Commission on Irrigation and Drainage is dedicated to enhancing the worldwide supply of food and fibre for all people by improving water and land management and the productivity of irrigated and drained lands through appropriate management of water, environment and application of irrigation, drainage and flood management techniques.
System design and management are key to efficient irrigation systems. This means to get optimum performance from your irrigation system, you must properly design, maintain and manage it. If you don't optimize any of these variables, you'll reduce system efficiency.
SYSTEM EVALUATION AND File Size: KB. The Manual for the Irrigation System Management Training of Irrigators Associations consists of six modules. Each module has an introductory portion and three topics.
The contents of each topic can be considered as inputs for a training session. Using the contents of each module, learning processes can be designed to follow the sequence of. of water supply systems in order to understand how this can be accomplished.
Chapter 2 presents a basic understanding of hydraulic fundamentals needed to accomplish water supply testing and evaluation accurately, and Chapter 3 presents water supply system evaluation methods for determining existing water.

The irrigation water is introduced into level or graded furrows or basins, using siphons, gated pipe, or turnout structures, and is allowed to advance across /5(14). 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. Flood irrigation is a typical method for leaching saline soil. Yet the practice needs a large amount of water, and it is difficult to remove salt uniformly throughout soil layers.
In this study, an experiment was conducted to evaluate leaching efficiencies of four different methods, namely: flood irrigation, spray irrigation, paper-covered Cited by: 1. Landscape Irrigation.
