| Abstract | 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. |
