Assessment of Boğaçay, Çamgazi and Sarayköy Irrigation Schemes by Statistical Methods

Irrigation schemes’ performance level isunsatisfactory in Turkey. Performance indicators used to assess irrigationschemes among others and years to monitoring. The large number of performanceindicators make assessment difficult to make a general assessment of irrigationnetworks. In addition, each performance indicator has a different effect on theirrigation network. For this reason, multivariate statistical evaluation methodwas developed including performance indicators by the researchers to analysethe performance of irrigation schemes. In this study, the irrigation networksof Sarayköy, Çamgazi and Boğaçayin different regions were evaluated by principle component and they wereranked among the irrigation schemes by quality index. As a result, waterdistribution performance indicators, financial indicators and agriculturalproduction-economic indicators showed different effects in the ranking ofirrigation networks. As a conclusion, it was determined indicators which areirrigation water distributed to per unit irrigated/command area, and output perunit irrigated/command area were important factors have important effect onranking of irrigation projects.
