A methodology is outlined for determining weekly estimates of the areathat can be safely irrigated by diversion irrigation systems. The method uses a regression model based on river flow, rainfall, and evaporation data. The analysis was carried out on two irrigation systems in the crop year 1970-71, and data were collected from the systems to check the predicted area irrigated. Recommended schedules of planting and water distribution were constructed from the analysis. These schedules, if followed, would lead to increased area planted and irrigated especially in the dry season.

The history of a pump irrigation project in Gatanduanes, Philippines, is traced. Three pumps were introduced to the area in 1969, and a farmers' association established. The problems of this association and its relationship with the man responsible for installation and operation of the pumps, are analyzed. In 1972, an additional project was initiated which attempted to strengthen the association. Its progress in dealing with problems of land reform, water distribution, and credit are stressed.

Twenty-one cylinder infiltration tests were conducted during irrigation of wheat on the shrinking/swelling vertisol soils of Kafr El-Sheikh, Egypt. Infiltration rates decreased rapidly from 720 mm/ hr for the first minute to 7.2 mm/hr at 2 hours elapsed time, with 1/3 of the tests showing soil sealing. In the majority of tests a well-defined two phase cumulative infiltration curve was determined. Significant correlations of antecedent soil moisture content in the 0-100 mm and 0-200 mm soil depth at the phase change, and average infiltration rate during the first phase were found. The first phase of infiltration was considered to represent flow of water through the soil macropores in the drier upper layer and water through the soil macropores. The second phase represented vertical flow into the wetter lower soil layers and filling of the finite storage space above the high water table. The analysis indicated a design application depth for wheat of not less than 120 mm for the first irrigation and 55 mm for subsequent irrigations under prevailing Abu Raya irrigation practices. Good water distribution across the field was facilitated by low long-term infiltration rates and high water table conditions. With the low second phase infiltration rates, water ponded in field depressions for prolonged periods could be detrimental to crops and requires provision for surface drainage. Precision land levelling would reduce this hazard.

The Egypt Water Use and Management Project team selected the Abyuha area, in Middle Egypt, to conduct irrigation management studies. The maize-cotton-sugarcane cropping pattern, typical in this area, is representative of much of Middle Egypt. The team characterized the major physical, hydrologic, biological, and socio-economic factors operating inthe system under study; then they analyzed the data and identified major factors that were acting as constraints or problems of the system. The results of the study were used to develop a research program designed to assist both governmental organizations and the farmer in removing, where possible, irrigation management constraints in the system. This process is called "problem identification".

A water delivery system in Middle Egypt was renovated to providecontrolled gravity flow for more efficient distribution and use of irrigation water. After thorough planning and design, structural specifications were prepared for watercourse renovation, hydraulic control structures, internal access roads, and land leveling. Contracts were awarded and construction was initiated. The effort to perform extensive renovation of a water delivery system at the farm level required an experimental approach to develop the best methods for quality construction with the least disruption to farming practices and irrigation schedules. A summary of the specifications, the contracts and costs, the construction procedures, and recommendations for future work were prepared.

This paper suggests actions which irrigation system managers can take to improve performance without additional resources. Managers can use methods of rapid appraisal and a straightforward set of questions to identify feasible improvements. These can be found in three spheres of activity: (1) scheduling water distribution, especially to save or better use water at night; (2) communications; and (3) farmer participation. Improvements can be identified and introduced at once. There is no need for managers to wait.
