Annex 4 Evaluation of irrigation performance. This section describes how to determine the performance of basin/furrow irrigation. It is assumed that the net irrigation water need of the crop is known (i.e. the net irrigation depth). This is compared with what happens during the actual irrigation practice.

Planning and Evaluation of Irrigation Projects: Methods and Implementation presents the considerations, options and factors necessary for effective implementation of irrigation strategies, going further to provide methods for evaluating the efficiency of systems-in-place for remedial correction as needed.

As the first book to take this lifecycle approach to agricultural irrigation. Each block is divided into two parts and each part is divided in about six bunded units (i.e.

the trial fields). A part of the land is irrigated by the basin irrigation method (i.e. flat basins), and a part is irrigated by the bed - and - furrow irrigation method. This measurement of the irrigation event is known as an evaluation.

In order to calculate the in-field distribution of water by the irrigation system, otherwise known as the uniformity, to work out the efficiency and to determine how adequately the irrigation system met the irrigation target application, specific evaluation procedures for specific irrigation systems must be.

Box Irbid, JordanCited by: 1. Basin irrigation evaluation. The estimates of basin application efficiencies are somewhat simplified by a small field slope and the prevention of runoff.

Water first entering the basin would advance to the end dyke and then pond on the surface. As the water surface rises, it will approach a horizontal orientation. This paper presents a framework irrigation managers can use in assessing performance of irrigation, and recommends a specific set of indicators for measuring performance that the authors believe are practical, useful, and generally applicable.

Although the primary focus is on the management of canal systems for agricultural production, the paper Cited by: 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.

The former method gives a general idea of the irrigation interval, whereas the latter method gives detailed soil moisture accounting in the field and is more robust than the former method. The water balance method can be used for real-time irrigation scheduling and can be linked to the climatic forecast to assess the agricultural drought.

Field tests were conducted to obtain irrigation evaluation and solute transport data. The data were used to calibrate and validate an advection-dispersion model for furrow irrigation.

This chapter explains in detail the concept and measurement of ‘water-use efficiency’ and ‘water productivity’ as applied at plant, field, farm, region/sub-basin, basin and national level through traditional and remote sensing based estimations.

A comprehensive framework for irrigation water performance assessment (IWPA) based on satellite data was proposed.

This framework consists of external IWPA (EIWPA) and internal IWPA (IIWPA). The. Land Evaluation: Methods in Land Evaluation, Volume 2 Volume 7 of (General Administration for Development Cooperation.

Irrigation methods. CHAPTER THREE: IRRIGATION METHODS AND DESIGNS  IRRIGATION METHODS  a) Surface Irrigation: Just flooding water. About 90% of the irrigated areas in the world are by this method.

 b) Sprinkler Irrigation: Applying water under pressure. Field experiments using conventional fertilization and fertigation for basin irrigation were performed. Based on measured data, the differences of spatial–temporal distribution between the nitrogen in surface water flow and that in soil with different Cited by: 6.

Performance measurement plays an important role in managerial control. However, until recently, most of the assessment practices in irrigation scheme have been focused on one-aspect evaluation, mainly field measurement. There is still lack of a comprehensive evaluation : Doudou LIN.Gravity irrigation method.

In this method of surface irrigation, water is applied to the field by furrow which are small canals having a continuous our nearly uniform slope in the direction of irrigation.A review of Basin (Contour) Irrigation Systems II: Research needs for evaluation and design Malcolm H.
