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.

The paper describes scientific management of irrigation for the seedbed, land preparation, and growth periods of lowland rice. The land preparation period is found critical for canal design, and appropriate formulas are discussed relating the area to be prepared with the duration of the period and available water supply. Water management for the crop after transplanting is also defined through formulas. Experience from Taiwan is used to estimate rotation intervals under conditions of variable soils, sources of water, and seasons.

A study of three of the farms of El-Hammami area in El- Mansuriya region, Giza Governorate, was carried out to evaluate the irrigation of sandy soils. The on-farm irrigation practices in the area indicated that the farmers at the beginning of the canal apply more water than those at the end of the canal. The irrigation application efficiency of the farmers at the tail end of the canal was greater than that of the farmers at the beginning. The data also indicated that subsurface irrigation due to seepage from neighboring fields contributed substantially to crop water use. The study showed that surface irrigation might not be the best way to irrigate these sandy soils.

The paper describes a field-oriented evaluation of the performance of eleven deep tubewell (DTW) based irrigation systems. In addition, the study served as a basis for developing a model that can be used in predicting the impact of various interventions (i.e., improvement of earth channels, lining of canals, upgrading on-farm water management practices, increase in pumping hours, etc.) on command area expansion. The methodology followed included intensive field data collection in five DTW command areas in Dhamrai (near Dhaka) and six DTW command areas in Thakurgaon (in northwest Bangladesh). Performance parameters utilized included conveyance, application, overall irrigation, unit, and pumping plant efficiencies. The impact of each of the interventions considered was then determined by comparing the predicted command under the modified system with that under the existing conditions. This, in turn, provides the necessary information for cost effectiveness analysis. The analysis indicates that DTW command areas could be increased significantly through measures including improvement of main and field channels, improvement of plot channels, better on-farm water management, land-levelling, and longer operating hours.

Drainage, groundwater withdrawals and altered irrigation practices are among the techniques for reducing waterlogging problems resulting from inefficient water use. However, these corrective measures are often not adopted since the private costs incurred by the individual operator quite often exceed the private benefits. Net social benefits are likely to be positive, so collective action may be appropriate. The overall objective of this paper is to develop an integrated approach combining both economic and physical considerations in order to evaluate possible collective alternative approaches to relieving waterlogging problems. Using survey data from the San Luis Valley, this paper presents a recursive linear programming model that includes both uncertainty and capital constraints. This model incorporates a weekly short-run water allocation model and a simplified water balance model of the groundwater to form a complete simulation model. The model was run using 20 years of historical climatological data to represent the long-run effects of policies which might be undertaken by the water users or by the Colorado State Engineer. Policy alternatives modeled include: Investment in canal lining, total conversion to sprinkler irrigation, various restrictions on groundwater pumpage, and a modified quota-market system. A comparison of the economic and physical results of these simulated alternatives is made and policy recommendations are suggested.
