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.

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.

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.
