A study of three of the farms of El-Hammami area in El- Mansuriya region, Giza Governorate, was carried out to evaluate the irrigation of sandy soils. The on-farm irrigation practices in the area indicated that the farmers at the beginning of the canal apply more water than those at the end of the canal. The irrigation application efficiency of the farmers at the tail end of the canal was greater than that of the farmers at the beginning. The data also indicated that subsurface irrigation due to seepage from neighboring fields contributed substantially to crop water use. The study showed that surface irrigation might not be the best way to irrigate these sandy soils.

Using a surface irrigation hydraulics model, relationships were developed between water requirement efficiency and the system design variables. Acrop production function was utilized to relate crop yield to the water requirement efficiency. Gross returns from the crop, and the costs of water, labor, ditch construction and crop production were considered in the optimization problem. Several system constraints were incorporated into the design process. The generalized geometric programming technique was applied to the optimaldesign of border and basin irrigation systems. The design variables were: the length of the run, inflow rate into the border, time of inflow, number of lengths of run, width of the border, and the number of border widths in the field.

The Ganges-Kobadak (G-K) Project is the largest surface irrigation system in Bangladesh. The study evaluated the performance of the system keeping in mind the objectives of the project to (1) increase food production, (2) control floods, (3) improve the drainage system of the area, (4) improve cropping patterns and intensity, and (5) improve the socio-economic conditions of the farmers. The methodology followed was an intensive survey approach. The performance parameters selected were pumping plant, conveyance, on-farm water use, and command area efficiencies; adoption of high yielding varieties and input use; and benefit-cost ratios of cropping patterns. Results indicate that pumping plant, conveyance, and kharif II command area efficiencies are relatively high, while on-farm water use and kharif I command area efficiencies were much lower. Both HYV adoption and input use were higher in 1984 than in 1983. Finally, benefit-cost ratios of selected cropping patterns ranged between 4.85 and 2.77 depending on whether recommended or farmers' management practices were followed.

Deals with water control and the management aspects of gravity flow irrigation systems in general. Briefly outlines the various types of gravity flow irrigation systems. Discusses water control including the main objectives and prerequisites for water control. Expounds on the management of irrigation systems for improved performance as including not only the management of water, but also information and controls. Lastly, the author outlines the components of an effective management plan.

The economic performance in 1974 of seven diversion irrigation systems ranging in size from 2,400 to 9,000 has is compared with their performance as initially projected. Construction costs are generally about 15% higher than originally projected, operation and maintenance costs are about 55% higher, and farm income benefits from irrigation are about double. The greater farm income benefits stem from the much higher rice prices in 1974 than those that were projected. Area irrigated and yields were both substantially below projected levels.
