Abstract:
Zuma irrigation scheme was evaluated for the technical and management performances of the
irrigation scheme. The reason, performance based technical and management evaluation is a
principal approach to improve the scheme performance. The study was done during the
irrigation season from October to December, 2016. The technical evaluation was made by
taking some selected performance indicators such as conveyance efficiency, water delivery
performance and maintenance indicators. Moreover, the management performance was done
by questionnaires. Primary data collection included field observation, household survey,
interview and discussion with beneficiaries were done. Discharge measurements were also
done in the canals. The results indicated that the main canal conveyance efficiency was found
to be 88.2 and 97.8%. The conveyance efficiency of secondary canals was 74.8 and 84% at
the lower and middle secondary canal sections respectively. The actual water delivery
performance of the main canal was 92%. This shows, the current canal structures are lower
than the design of the canal capacity. Management performance provided to the beneficiaries
was not the same as to the intended.
