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.
5 Kundu, S. S.; Skogerboe, G. V.. 1980. Field evaluation of methods for measuring basin irrigation performance. Fort Collins, CO, USA: Colorado State University. xviii, 118p. (Water management technical report no.59)
(Location: IWMI-HQ Call no: 631.7.8 G000 KUN Record No: H0345)
A detailed description of field procedures employed to obtain necessary data for evaluating basin irrigation performances of several irrigation events is outlined. Two analytical techniques are described and used for calculating infiltrated water depths through station-areas delineated by a grid system within the basin. Both techniques require an infiltrometer test and infiltration opportunity time of each station-area during an irrigation event. A modified volume balance technique is described and is used to develop an infiltration equation which should represent the actual infiltration characteristics of the entire basin during an irrigation event. The infiltrated water depth of each station-area is also calculated by using the infiltration equation developed by this method. All three methods are used for measuring basin irrigation performance and their applicability for measuring performance parameters is compared.

(Location: IWMI-HQ Call no: 631.7.8 G000 PER Record No: H0327)
A comprehensive definition and description of basin irrigation is given. A procedure is outlined for the design and evaluation of basin irrigation systems, showing the interactions between the various basin characteristics, the operational parameters, the management parameters, and the performance parameters. A general model is discussed by considering the various functions upon which it must be based (infiltration, advance, recession). A simple model for the determination of the infiltrated water distribution under basin irrigation is also presented. It is shown that the actual distribution can be determined from limited field data. The model can be applied to both level and sloped basins. Comparison with other more complicated models shows satisfactory agreement in the distribution. A complete infiltrated water distribution under basin irrigation can be approximated from limited field observations. Field procedures are described that will provide the parameters required to determine the distributions. As only two of a possible four parameters are sufficient to define each distribution, the selection of these parameters should be made on the basis of circumstances under which the field observations were made. General guidelines are given for the selection of the most reliable parameters. The main advantage of the method is its simplicity in both the field measurements required and in the data analysis. The procedure suggested is suitable for most practical cases, especially as a preliminary evaluation when detailed studies are not warranted.
7 Peri, G.; Norum, D. I.; Skogerboe, G. V.. 1979. Evaluation and improvement of border irrigation. Fort Collins, CO, USA: Colorado State University. xv, 105p. (Water management technical report no.49C)
(Location: IWMI-HQ Call no: 631.7.8 G730 PER Record No: H0326)
The evaluation of border irrigation requires the use of a model that relates the operating conditions to the irrigation results, such as: (a) total water quantity delivered to the border; (b) water losses outside the border by runoff; (c) average depth of application; and (d) water distribution within the border. Evaluation for improving border irrigation can be carried out in two major ways: (a) field tests; and (b) theoretical models. The improvement of border irrigation based on field tests requires the estimation of the infiltration equation and the advance and recession for a specific inlet stream and border parameters (slope, length, surface). The performance parameters can then be calculated to determine the irrigation performance and the need for improvements. Then, the operating conditions that are to be changed can be determined. This analysis comprises two stages: (a) utilization of the field test data already available; and (b) implementation of the recommended changes for further field tests. Theoretical models for the evaluation and improvement of border irrigation performance enable one to predict the water distribution and losses for a given set of conditions, without direct field measurements. Only limited amounts of preliminary field work are required to predict the irrigation performance for a wide range of parameters and variables. Available models are described, as well as the process for applying these models.

Irrigated agriculture, by its very nature, is a joint enterprise that requires the cooperation of all water users and those government agencies and other organizations that provide services to farmers. This book illustrates irrigation associations and how they can help a local area increase its agricultural productivity through farmers working together to construct, manage, maintain and/or rehabilitate the irrigation systems that they can use.
