Abstract

For a number of reasons, many irrigation projects are underperforming; these need be fixed to raise the programs' productivity and efficiency. The purpose of this study was to evaluate the effectiveness of the Ujummo irrigation scheme in western Ethiopia's West Wolega Zone. The average conveyance efficiency (70.3%), field application efficiency (38.62%), average water storage efficiency (61.1%), irrigation uniformity (90.68%), and overall irrigation efficiency (27.14%) were all measured in the field. But the distribution of water was uniform, maybe because canal portions experienced disproportionate losses. The scheme also had relative water supply of 15.91, relative irrigation supply of 10.89, output per unit command area was 1324.24 ($/ha), its output per unit irrigation supply was 0.103 ($/m³), its output per unit water consumed was 0.67 ($/m³), its sustainability of irrigation area was 0.82 and its irritation ratio was 1.34 and this indicate there is expansion of irrigate land without additional any irrigation structures and use only the design capacity of the scheme.
