Abstract

The compatibility between the used methods of lining for open channels in permeable soils is the main indicator about the conservation efficiency of irrigation water, which means minimizing the quantities of water losses through the water transportation process. From this standpoint, and within the framework of the national project for the rehabilitation of irrigation canals in Egypt, which is implementing nowadays all over the villages of the Egyptian countryside, this work presents a field study for one of those canals for which the rehabilitation process is being implemented. The field study carried out in one of the Middle Egypt villages in the western desert, El-Minia governorate, to monitor the extent to which the lining being implemented with the proposed method is compatible with the nature of the canal's area, topography, soil types, groundwater levels, and so on. The case study that we are about to present, is for Al- Khofoog canal which is about 6.730 km. long, engraved in a very fine sandy soil to irrigate about 6000 feddans. It was chosen due to the problems facing the implementing process, how to overcome and introduce the most suitable engineering treatments which may more compatible with the site properties and nature, supported by a quick economic feasibility study. This field study, that was conducted in the Middle Egypt region, is presented, hoping that it will be integrated with other similar studies to be conducted in other regions, representing North and South Egypt, for leading to develop a guideline, and a map includes the most appropriate rehabilitation methods in each region, according to its nature, and characteristics in that region in order to save effort, time, and money, maybe spent for implementing an unsuitable method, regardless of the site's privacy, nature, and expected problems.
