Abstract:
Watercourse conveyance efficiency and water availability was estimated on a watercourse command of SCARP Tubewell # 56L and canal outlet (mogha) # 62394L at Bhaiwal, Sargodha. The selected watercourse command comprised of 401.3 ha of command area and 41 farms. The loss rate of 1.46% per 100 m length of channel was used as constant loss rate function for the analysis of conveyance losses. The mean conveyance efficiency at square inlet of watercourse command of 70% was observed. The average conveyance efficiency at field gate was about 67.8% over the selected watercourse command. The average actual water availability was 83.6, 64.7 and 54.0% of the water allocation at the head, the middle, and the tail farms, respectively. The total length of the main watercourse was about 9.0 kilometers, whereas, the total length of the branch watercourses was about 30 kilometers. The main watercourse contributed 93% of the total conveyance losses because main watercourse was in operation for 100% time of each turn. The field watercourses were in operation of about 4.3 hours per week per square of the selected command.
