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.

Over half of the water supplied to the watercourse at Tubewell 56L was lost before it reached the farmer's fields. This loss was primarily through the upper porous portions of the banks and in the vicinity of junctions where banks were thin. The 35 farmers in the 900-acre area served by this watercourse were motivated to organize themselves to rebuild their own earthen watercourse, according to specifications drawn up by Pakistani engineers. Low cost concrete diversion structures were developed and installed at junctions to eliminate continued burrowing of soil and degradation of banks near the junctions. The improvements reduced losses to about one-half their previous values and increased deliveries to the fields by over 50 percent. This watercourse improvement appears to be an ideal component for a development program designed to increase crop production. However, farmers require further information on how to use this water and other inputs to optimize crop production if they are to obtain full benefits from this extra water.

This research program was funded by USAID, organized by CSU and sent out to identify good investments for developing countries in water management. Loss of almost half of the water from watercourses was identified as a primary waste of irrigation water which is a limiting factor in crop production in Pakistan. Physical causes of the loss were identified as high porosity of upper portions of the banks due to burrowing of soil for weekly construction of dams, and rising levels of water in the watercourse due to vegetative growth and sedimentation. Difficulty in organizing farmers to accomplish regular cleaning and repair was identified as an underlying sociologic cause of the loss. Experimental masonry and concrete watercourses were built by the government and given to the farmers. They were too expensive to provide a nationwide solution. The farmers did not appreciate and maintain them because they had no investment therein. Other lined watercourses on which the government paid for materials and the farmers provided labor were better appreciated and maintained, but took longer to build and still required large amounts of cement and were too costly for a national program. Cooperative improvement of the earthen channels by the farmers with the government providing the materials and design for concrete control structures at the junctions was developed as a program which had a benefit:cost ratio of at least 3 to 1 and was eagerly accepted by the farmers in a study which involved a series of case histories. Subsequent studies indicated that a good and regular cleaning and repair program would save almost as much water and provide higher benefits with much lower government input. However, the watercourse improvement plan with its concrete control structures was more eagerly accepted by the farmers. Full benefits of the improvement were obtained only by those farmers who organized themselves to clean and maintain their watercourses regularly.

The manual assists both national and donor agency planners to determine the need for and carry out a program to improve the tertiary irrigation conveyance systems. Topics covered include evaluating and diagnosing problems in the present channel systems, proposing and testing solutions to the diagnosed problems, combining the solution techniques into improvement strategies, evaluating the improvement strategies and developing the institutions necessary to carry out the improvement programs. The manual deals both with processes, which will be of primary interest to the planners; and techniques, which would be useful to the engineers, economists and sociologists.

Over half of the water delivered from the canal system to the watercourses managed by the farmers is not made available to the farmers' crops in Pakistan. Most of this water loss is due to loss of water through the banks of the watercourses. Lack of maintaining these banks and lack of cleaning the watercourse is a result of inadequate organization of the 10 to 150 farmers who use the watercourse, and a deficiency of knowledge concerning the amount of their water which is being lost. Various methods of watercourse improvement have been evaluated including concrete and masonry linings and simple earthen improvements of the ditches with concrete control structures, junctions, and turnouts. With the cost of labor low in Pakistan, the earthen improvements with concrete structures appear to be the best investment. Farm water management improvement programs have been implemented in most of the provinces which include this type of watercourse improvement, land leveling and advice to the farmers on how and when to irrigate his crops to optimize his production. The rate at which personnel can be trained to help the farmers implement these improved water management practices is limiting the rate of implementation.
