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.

Many farmers in Pakistan experience difficulties due to insufficient head or elevation of the water in their irrigation system. This problem is especially acute on public tubewell supplemented watercourses. A low head jet pump device which utilizes the excess energy of tubewell water to raise the elevation of surface canal water was developed to help solve this problem. Both laboratory and field studies are described which show that these watercourse junction jet pumps can solve the problem, even though their efficiencies range from only 14 and 18%, and can be built inexpensively. Their primary use will be to: (a) allow canal turnouts, which are often submerged when the tubewell is turned on, to flow freely; or (b) irrigate, or more efficiently irrigate, the higher elevation croplands. Both graphical and analytical procedures are described for the design of jet junctions.

Tertiary irrigation conveyance systems (watercourses) in the Indus Basin lose 30 to 50 percent of their flow. Watercourse systems were studied in depth by ponding and inflow-outflow methods to determine functional relationships between several measurable parameters and the loss rates. The objective was to determine simple design changes that are low cost and can lead to increased conveyance efficiencies in the eastern channels. Statistical analysis of the collected data indicated that: 1. Watercourse loss rates (lps/100m) increase with, but slightly less than proportional to, the usual flow rate in the channel; 2. Loss rates are lower in more often used channels; 3. Loss rates are higher in elevated channels; 4. Loss rates are very sensitive to changes in flow depths, and thus increase with upward fluctuations in flow rates or roughness coefficients; and 5. Intake rates into upper bank soils are very high and are apparently caused by extensive rodent and insect burrows inside the banks.
