Infiltration opportunity time in level or nearly level borders

Abstract

The study was conducted in 1982 with an objective of finding out the infiltration opportunity time in nearly level border strips. The results revealed that a discharge rate of 2 l/s/m is the best for irrigating nearly level borders of 4-6 m width. This discharge rate gives almost equal opportunity time throughout the entire length of the strip excepting at the downstream end, thus giving better distribution efficiency. The recommended length of strip is upto 45 m and these can be laid in the direction of natural slope.
