Improving the irrigation system, and in consequence the irrigation efficiency became an essential issue with the limitation of water resources, and defining the optimal strategy to improve the irrigation system depend on the accurate investigation of this system. The objective of this study is to investigate different components of the Egyptian irrigation system. A typical command area at the north of the Middle Delta (Mit Yazid command area) was selected to represent the Egyptian irrigation network, and MASSCOTE approach was used as an assessment tool. Mapping System and Services for Canal Operation Techniques (MASSCOTE), which was developed by FAO, is a pre-improvement evaluation approach. The approach provides a systematic way to evaluate any irrigation system, which gives a chance to compare this system with other irrigation systems. The approach consists of ten steps in two categories. The first category investigates the irrigation system, and the second category introduces the modernization suggestions based on the results of the first part. The current study applied the first category, which contained applying Rapid Appraisal Procedure (RAP), checking the capacity of the irrigation system, and assessing the sensitivity and perturbation at different control structures.The assessment defined the specific weakness of the irrigation system and it showed that irrigation performance decrease significantly at the lowest level of the system. The reasons for such decrease and the effect of Irrigation Improvement Project on improving the performance were discussed.
El-Bagoriya canal is a main canal in the Middle Delta and it is the main water source for West Kafr El-Sheikh irrigation directorate. As originally a natural canal, El-Bagoriya canal has specific characteristics that affected its hydraulic performance, and which resulted in a problem in conveying required water supply to downstream irrigation directorates. With the installation of two new municipal stations on the canal, there was a plan to dredge the canal inside El-Monofiya irrigation directorate to increase its hydraulic capacity. A research project was conducted to help the irrigation directorate implementing the dredging in the best way. The research activities included surveying the cross sections using modern surveying techniques, using ArcMap program to develop contour maps from the surveyed points and derive cross sections from these counter maps. The activities also included using the simulation model to check the original situation, the suggested dredging scenario, and the actual dredging. The results showed that the suggested dredging could improve the flow inside the investigated reach from 53.5 m 3 /sec to 64.5 m 3 /sec while maintaining minimum water slope inside the reach. Actual dredging could improve the flow inside this reach to 57.5 m 3 /sec while maintaining the same water slopes.
