(Location: IWMI-HQ Call no: 631.7.1 G65D LEN Record No: H0131)
The paper analyses some of the tools which will be needed to make the management of irrigation systems less of an art and more of a science. The paper is divided into four parts: (1) performance criteria in irrigation management; (2) techniques by means of which performance might be monitored for large-scale irrigation systems; (3) diagnostic tools required for irrigation management and their desirable characteristics; and (4) management tools available for analyzing interventions to improve irrigation performance.

The purpose of this report is to document the actual irrigation practices of the farmers in two Egypt Water Use and Management Project (EWUP) areas, Abyuha in El-Minya Governorate and Abu Raya in Kafr El-Sheik Governorate. Data on the farmer practices were abstracted from the EWUP R4 Farm Records for the 1979-1980, 1980-1981, and 1981-1982 record years. The study case data were divided into 15 day periods with the winter closure period eliminated from the analysis. A comparison of the actual planting and harvest dates with the expected dates indicated that the actual dates were later than the expected dates by about two weeks. A comparison of the actual number of irrigations with the expected number of irrigations indicated that farmers apply close to the expected number or fewer. The analysis indicated that irrigation gaps for some crops range as high as 89 days. The aggregate demand on the delivery system in both study areas tended to be highest in the periods immediately before and after winter closure and the summer periods, June through September. Comparing the measured water discharged into the Abyha canal with an estimated demand for selected periods indicated that relative fluctuations in the delivery of water correspond fairly well to the demand during the same period. A comparison of the measured water discharge into the Om Sen canal with an estimated demand for selected periods indicated excess delivery of water during the winter periods, periods where shortages of water delivery could have occurred, and a general lack of correspondence of the fluctuations in discharge to the fluctuations in demand.

This report describes the characteristics of the irrigation system in the old lands, various interventions that were tested by the project and recommendations to improve irrigation water use and management. In addition a list of the technical reports produced by the project is given. This report was the basis for the National Conference held from 18-20 March, 1984 where the findings and recommendations of the project were discussed in detail by approximately 150 Egyptian irrigation and agricultural specialists.

Discusses different water delivery systems and scheduling policies, based on intensive research underway by the U.S. Agricultural Research Service and how these might be applicable to managing irrigation systems elsewhere in the world. Presents an extensive section on scheduling policies of irrigation projects which includes the system components, scheduling terminology, and the relationship between scheduling policy and water conservation. Concludes with brief coverage of some structural and equipment aspects of water control and the measurement of water flow.

Production benefits of improved allocation of irrigation water are often difficult to measure. In situations of irrigated rice cultivation, both ex post estimates of such benefits and ex ante estimates of the maximum potential benefits of further improvements in allocation of a given water supply are possible using a conceptual framework which (1) functionally relates weekly water supplies to weekly measures of average water shortage on individual paddy fields; (2) aggregates the weekly water shortage measures into a seasonal water shortage index; and (3) relates, via a production function, the seasonal water shortage index to yields. An empirical application of this framework estimates the potential increase in production from further improvements in water allocation in one Philippine irrigation system to be negligible.
