Abstract

Lining is an effective technique to improve the watercourse performance. The Directorate of On-farm Water Management (OFWM) normally lines 15-30 percent of the watercourse length whereas the farmers insist to line more than that. Present study was carried out during at watercourses 5486-R, 114626-R and 116928-R on Shahkot distributary and relevant data were collected to compute optimum length of lining based on channel usage time and trade off point. Statistical analysis predicted that it is economical feasible for lining the watercourses as 49 to 54 percent, earthen improvement as 21-29 percent and cleaning the watercourses as 11-13 percent of total length of watercourses. This technique is more reliable as conclusive results could be obtained through it as compared to graphical approach where there was biasness in scale measurement. On the other hand graphical approach is used to determine the quick representation and trend of the factors.
