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.

Vol. 1 - Theory. A theory for simulation and optimization of an irrigation system to evaluate improvement alternatives was presented. The mathematical simulation model of an irrigation system was developed combining existing models of conveyance, application and water use subsystems. The performance of the subsystem simulation models was verified using available field data from Pakistan. A methodology for the optimal design of a level basin irrigation system was described. Irrigation system improvement alternatives such as canal lining, earthen improvement of the application system were evaluated. Vol. 2 - Application. Wheat production on a watercourse in Pakistan was analyzed. Models for water conveyance, application, and water use subsystems were calibrated with data from the study area. The existing irrigation system operated at a 39 percent application efficiency and 53 percent conveyance efficiency. Optimal design of the application system with precision land leveling provided net benefits of 3625 rupees (Rs) compared to Rs 2612 under traditional field conditions. Canal lining was not economical. Earthen improvement of the conveyance system was beneficial to the farmer with a net profit of Rs 3304. Combined improvement of the application and conveyance systems almost doubled the total net benefits over the traditional system, but with an increased level of investment. The increase in benefits was mostly a result of the increased irrigated area that could be irrigated after the improvements. The benefit/cost ratio of each improvement alternative was different. The difference in benefits between improving the conveyance system and the application system was small, but there was a significant difference in net benefits between any single improvement and the combined improvement of the application and conveyance systems.

A research project was carried out on large sites within irrigationsystems to determine the benefits of irrigation to yields of lowland rice. Datawere collected under farm level conditions to establish yield response to days of moisture stress. A model was then developed and employed to relate irrigation, rainfall and water-use parameters to days of moisture stress, and thus to yields. Although yield benefits due to irrigation were substantial for both seasons, they were seriously depressed because of imperfect irrigation, particularly in the dry season. Neither the height of paddy bunds nor the amount of rainfall in the sites were of major consequence to grain yield. Considerable variation in water-use was observed among the sites, but it was generally found that sites with low water-use efficiencies showed the greatest yield benefits, and vice versa.

The EWUP conducted an irrigation research and development program from 1978 to 1984 in the Abu Raya area served by the Daqalt Canal in an effort to improve irrigation water management. Using an interdisciplinary effort, the program included the design, construction and operation of the Daqalt Canal system to deliver water to all farms in sufficient quantity at appropriate times to meet all water needs; to deliver water at an adequate and equitable flow rate and head and to minimize surface losses to drains. The original system was designed, constructed and operated under certain physical and operational assumptions that would minimize use of water while maximizing crop yields for all individual users. The report describes the physical characteristics of the existing system including water supply, canal structures, canal and mesqa surveys, soil conditions, crop patterns, water table levels, on-farm irrigation and water delivery requirements. The socio-economic characteristics of the existing system were also evaluated to assist in developing an equitable water user management program. The Daqalt Canal does not meet its original objectives due to water shortages, inadequate and inequitable flow rates and heads, and large surface losses to drains. These problems are caused by ineffective physical structures operation, conflicts existing with irrigation timing preferences, and poor canal maintenance. As such, the performance of the system falls short of that desired due to incorrect assumptions and improper management, and the entire water delivery system requires renovation within the context of the larger irrigation system. It is recommended that a complete hydraulic model of the existing Daqalt system should be developed under the constraint of available water levels in the Mit Yazid Canal, and the design re-evaluated in light of this model. The renovation process should continue, and water users themselves amalgamated into the design and operation of the water management plan.

A study of irrigation performance in selected irrigation systems of Cirebon, West Java. Describes the institutional and organizational realities of irrigation systems. Presents an evaluation of crop performance and response function of paddy to irrigation via two basic concepts, namely Relative Water Supply and Water Shortage Index. Lastly, it deals with the equity in water allocation and the economic value of water.

Examines the nature of water allocation in two new farmer-managed irrigation systems in the Dumoga Valley of North Sulawesi, Indonesia. The purpose of the research was three-fold: 1) to identify the social and physical aspects of these systems which influence how water is allocated among farmers' fields; 2) to analyze the interplay between rules and processes of farmer interaction; and 3) to examine the equity and efficiency of water use by farmers.
