Abstract

The problem at present is as to how best the available water can be utilised for maximum agricultural production. Therefore, the engineers concerned with Agriculture are now concentrating their attention in devising ways and means for efficient transmission and application of irrigation water to fields. It has been well established that a large portion of irrigation water is lost in field irrigation channels by seepage during conveyance. The water that percolates deep into the ground below the effective root zone of the crop is not available for plant growth and hence it becomes a loss to cultivator. In developing countries like India, adoption of the generally accepted lining materials for farm channels to prevent seepage is prohibitive on account of cost and hence the need for developing cheap methods of lining small field irrigation channels.
