HS-83-13 A research study submitted in partial fulfillment of the requirements f or t he degree of Master of Engineering, School of Engineering and Technology Research Studies Project Report (M. Eng.) - Asian Institute of Technology, 1983 Chapters 2 to 7 are Literature Reviews compiled from the FAO, ILO a nd the United States Bureau of Reclamation. They provide the available information on the techniques of canal linings. Linings are important as in addition to the conservation o~ water supply, they reduce damage to low lands from seepage , reduce operation and maintenance costs and even increase structural safeties. The stock of water on a global basis is fixed but the demand for water is on the increase . In developing countries, more than 90% of the total consumption of water is f or irrigation (adapted from ILO, 1977). Large amounts of capita l providing irrigation facilities are not efficiently used in agriculture a nd wastage is consider able. Water seeping from unlined canals and laterals often collects in low-lying lauds , there.by rendering them unproductive. Dams, reservoirs and distribution systems designed and constructed with greater: capacities to provide for such losses are costly. The reclamation of water-logged land by constructing drainage system where practicable is also costly. Therefore, good engineering practice demands that all cost factors - the value of land, water and the cost of engineering features - be property and carefully evaluated in the economic construction of canal systems and that this evaluation be projected into the future. The choice of materials used was based on criteria such as availability, low cost , relatively high watertightness, resistance to wearing, weathering , soil and water attack. Finally, the application of low-cost indigenous technology for lining canals could make a positive impact b y increasing cultivated areas and employment opportunities. This study examines the property of lime a nd lateritic soil as a material for canal linings . Its performance in water over a number of days un der laboratory conditions has shown promising results. Should an area be abundant in lime deposits as well as lateritic soil, it is worth while to consider lining an irrigation c anal with a mixture of lie and lateritic soil, in place of concrete linings.
