Vol. 1 - Theory. A theory for simulation and optimization of an irrigation system to evaluate improvement alternatives was presented. The mathematical simulation model of an irrigation system was developed combining existing models of conveyance, application and water use subsystems. The performance of the subsystem simulation models was verified using available field data from Pakistan. A methodology for the optimal design of a level basin irrigation system was described. Irrigation system improvement alternatives such as canal lining, earthen improvement of the application system were evaluated. Vol. 2 - Application. Wheat production on a watercourse in Pakistan was analyzed. Models for water conveyance, application, and water use subsystems were calibrated with data from the study area. The existing irrigation system operated at a 39 percent application efficiency and 53 percent conveyance efficiency. Optimal design of the application system with precision land leveling provided net benefits of 3625 rupees (Rs) compared to Rs 2612 under traditional field conditions. Canal lining was not economical. Earthen improvement of the conveyance system was beneficial to the farmer with a net profit of Rs 3304. Combined improvement of the application and conveyance systems almost doubled the total net benefits over the traditional system, but with an increased level of investment. The increase in benefits was mostly a result of the increased irrigated area that could be irrigated after the improvements. The benefit/cost ratio of each improvement alternative was different. The difference in benefits between improving the conveyance system and the application system was small, but there was a significant difference in net benefits between any single improvement and the combined improvement of the application and conveyance systems.

This report describes the results of theoretical analytical and field studies related to the problems of seepage and lining of the enlarged Ismailia Canal, Egypt. Direct measurements of seepage from the canal are reviewed and analyzed. Future seepage is estimated by using idealized models, that however ignore the possible existence of natural sealing by Nile silt. To investigate this hypothesis the HRS In Vibro-corer was operated on the canal - the first application in freshwater conditions. Corers were retrieved from the canal bed in an 8km reach with moderate success. The efficiency of the corer is evaluated in detail from the data obtained. The cores were prepared and analyzed at the Delta Barrage Laboratory. The results are described herein with their implications on the sealing phenomenon. Suggestions for extending the present studies using direct seepage measurements are explained in order to arrive at a logical decision whether to proceed with lining the canal. The work is part of a continuing research co-operation with the Hydraulics and Sediment research Institute, Arab Republic of Egypt.
