High water table levels presenting hazards to crop growth were measured at field sites in upper, middle, and lower Egypt. Water table contribution to evapotranspiration was significant at each site. A water balance model of the water table aquifer was used to predict the effect of various interventions on water table levels. Desirable lower water table levels could not be maintained through on-farm irrigation efficiency improvement including lining of on-farm channels while using surface irrigation methods. Branch, distributary, and private canal lining would have negligible effect on water table levels. Corresponding increases in required water deliveries would be expected.

A survey of 52 small-scale pumping units in Quezon and Batangas provinces in 1971-72 reveals that pump irrigated rice farms had positive net returns, with the wet season returns slightly greater than those of the dry season. But pump systems in the study areas performed poorly. They had low pump discharge rates and served limited areas. Four inch pumps had a greater average pump discharge than 5-inch pumps operating even at lower revolutions per minute. No substantial differences were found in yields of farms irrigated from different water table depths, or of different soil types. There were significant differences in pump discharge among soil types although they were not significant with respect to depth of water table. It was also found that area served was more dependent on available irrigable land than on soil type or water table depth. The study revealed that water is often conveyed through poorly maintained earth canals which we believe considerably reduced the efficiency of water use. The most common method of irrigation fee payment is 20 percent of net product shared by the tenant and landlord in both the wet and dry seasons. The major problem of pump owners is the lack of cash for pump repairs.

This paper presents the findings of a field experiment to secure farmer participation for system design and water management work in major irrigation scheme in Sri Lanka. The approach adopted was to employ a change agent to enable farmers to group into organizations based on a common hydraulic area. During the two and a half year period, over 200 farmer organizations were formed and farmer participation was successfully obtained, not only forsystem design, re-construction, operation and maintenance work but also for a few other activities. The paper concludes the need for development of human resources in addition to the investments on physical rehabilitation work.

A vortex tube sediment extractor has been installed in Chatra Main Canal, Nepal. During the 1982 monsoon, field measurements were carried out on this tube to enable a comparison between observed values of efficiency and the values predicted by the Hydraulics Research design method. This report provides the analysis and results. The report also looks briefly at sediment problems overall in the canal, and at a combined operation strategy for two vortex tube installations.

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.

Examines the responsibilities undertaken by government agencies at the central, provincial and local government levels in the field of irrigation and drainage development in the context of the objectives and targets of Indonesia's development plan, Repelita III. Identifies the current level of financial contributions being made to perform these responsibilities by central and local governments respectively and any other significant sources such as international aid and payments to village officials. Considers current target levels of operation and maintenance expenditure and examines current methods of determining local variations in O & M requirements. Examines possible problems caused by the multiplicity of sources of finance for irrigation and drainage O & M and by the absence of local taxes or charges specifically earmarked for this function. Also examines possible problems caused by the different boundaries of the ecologically determined zones on which irrigation management is organized and of the administrative zones of the kabupatens. Finally, the paper suggests what criteria might be adopted in assessing the future scale and structure of central and local government financial contributions to the execution of irrigation and drainage programs at the provincial and local government levels and what degrees of discretion should be allotted to local government agencies in deciding their detailed use.
