Conteúdo: | Definition of the problem; Method of investigation applied; Data processing: Grouping of areas; definitions of efficiencies; Calculating theefficiencies; Efficiency terminology and reuse; Accuracy of the calculated efficiencies. Some results not directly related to irrigation efficiency: Field irrigation method versus irrigated area; Farm size distribution; Number of farms served by group inlets; Project staffing. Analysis and evaluation of the data from the questionaire with respect to irrigation efficiency: Conveyance efficiency; Conveyance efficiency versus average irrigable area; Conveyance efficiency versus size of rotational unit; Conveyance efficiency as a function of technical equipment; Distribution efficiency; Distribution efficiency versus farm sizeand soil type; Distribution efficiency versus duration of delivery period; Farm inlet versus group inlet; Field application efficiency; Influence of field irrigation method on field application efficiency; Effect of depth of application on e (a); Field application efficiency versus farm size and soil type; Influence of farm flow rate on applicationefficiency; Tertiary unit efficiency; Influence of flow rate at farm inlet on tertiary unit efficiency; Relation of water charges to tertiary unit efficiency; Relation of tertiary unit efficiency to method of water supply to the farm; Irrigation system efficiency; Relation of irrigation system efficiency to actually irrigated area; Influence of project management on irrigation system efficiency; Everall or project efficiency. Practical application of the study results with some examples. Evaluation of the applied approach. Conclusions and recommendations.
