Evaluation of Different Canal Lining Techniques

Abstract

Water is an essential element which is required to sustain life on earth. However, it’s depleting at an alarming rate due to which it will become a serious problem in the near future for the world. Pakistan is among the list of countries which are considered as “Water Stressed”. Since, Pakistan is an agricultural country, its economy is completely dependent on the agricultural sector and almost 70% of the workforce is employed in it. A vast network of canal system is present in the country which is considered as largest in the world, is responsible for providing access of water to various farms throughout the country. However, almost 60% of the water entering in this canal system is lost due to various factors with major losses occurring due to seepage, even before it reaches its destination. This study aims on evaluating one of the many methods and techniques i.e. canal linings, which are employed to counter these losses. A comparison is done in this study between different types of lining in order to determine the most efficient and cost friendly that can be used to line the water channels in a specific region.
