The conveyance losses were found 13.2%, 11.8% and 7.8% in watercourses Sarai, Derkot and Mera Dadu, respectively, which resulted in conveyance efficiency of 86.8%, 88.1% and 92.4%, respectively. Results showed that conveyance losses increased and conveyance efficiency decreased with the aging of watercourse. Hence, more repair and maintenance is required for aged watercourses to minimize conve...
