Assessment of Agricultural Water Use in Irrigation Schemes of DSI 15th Region

Much of the food need saresupply by irrigated lands. therefore, efficient wateruse is important in irrigationschemes. forthispurpose, wateruse is continuouslyassessed in irrigation schemes to find out possible problems in advance and to propose solutions for those problems. achieving successful and efficient irrigation; the operation of irrigation facilities within a plan is made possible by following the application and evaluating the results in detail.in this study, according to the results of theirrigation of the suruç plain, akçakale, şanlıurfa-harran, yaylak andupper harran irrigation systems of the dsi 15th regionirrigationfacilities in 2016 has been assessed to water use in agriculture, water use efficiency indicators. project area gross production values (pabüd) fortheyear 2016 of the irrigation water in the study area; 1802-2228 ₺ / ha, actually the irrigated area gross production values (fsabüd); 1836-3706 ₺ / ha, gross production values for deflectedwater (sskbüd); 0,10-0,29 ₺ / m^3, gross production values for irrigation water requirement (ssibüd); 0.16-0.33 ₺/m^3, water contentrates (sto); 0.46-1.79 and irrigationratio (so) values are; 58-116%. the results obtained in the study were; it will contribute to the determination of the efficiency and the development possibilities of irrigation projects, to provide data to assist in the design of new systems, and to compare different methods, systems and operating models that will be the basis of economic decisions. also; it is a guide in the evaluation of water usage in irrigation networks.
