Assessing the Performance of Irrigation Schemes in Antalya Valley Located in Mediterranean Region of Turkey
(Maik Nauka/Interperiodica/Springer, 2015) Özmen, Selçuk; Kaman, Harun
This study examined evaluation of the physical and financial performance criteria of 24 irrigation schemes in Antalya Valley located in the Mediterranean Region in Turkey between 2007 and 2012. In this study, physical and financial performances included irrigation ratio, sustainability of irrigated area and relative water supply ratios, and water fee collection efficiency and service area per personnel, were examined. The results of this study indicated that irrigation ratios of schemes are between 12 and 84%. The rate of sustainability in irrigated land of schemes was close to 1.0 except Caybogazi, Deniztepesi and Dosemealti schemes. The relative water supply of most of the schemes such as Aksu-North, Aksu Middle, Alara Left Bank, Caybogazi, Gazipasa, Karaman Duraliler, Koprucay Right Bank, Kumluca Birlik and Manavgat Right Bank is higher than 2.5 because they consumed more water. The water fee collection efficiency was between 28 and 100% while service area per personnel between 10.7 and 1834.8 ha/person in all schemes from studied area. However, irrigation ratios of some schemes are needed to be recovered. The water fee collection efficiency and service area per personnel in most of schemes are satisfactory.
