Abstract
Watercourse losses were studied on a walercourse No. 52810-L located at Shahkot distributory. The conveyance losscs were found 41% comprising 19.5% on main watercourse and 21.5% on farmer’s branches. Improvement of only main watercourse reduced the losses [rom 19.5% to 9.75% but in the unimproved farmer’s branches, the losses were incrcascd from 21.5% to 24.5%. Afler the improvement of total system, ic. main and farmer’s branches a saving of 50% of losses was observed. The component of dcep percolation was not affected much, which was 10% before any improvemcat and 7.26% after improvement of complete watercourse system. The study suggested the renovation of complete watercourse system including main as well as farmer’s branches.
