dc.description.abstractIn this study, some physical and economical water use indices (WUI) were evaluated and discussed in two different irrigation schemes. Data were collected from Devegecidi and P2 Irrigation Schemes in Southeastern Anatolia Region of Turkey for two irrigation seasons, 2013 and 2014. In physical WUIs,total water use efficiency was projected as 54 % for delivering water to the irrigation schemes; those were 20.6-28.8 % and 36.9-43.1 % in Devegecidi and P2, respectively. Water supply and physical water productivity (WP) in weighted mean were 1.90-2.62, 1.26-1.46 and 0.314-0.318 kg m(-3), 0.477-0.495 kg m(-3) in Devegeicidi and P2, respectively. Water charges are based on crop type and per irrigated area in the irrigation schemes as it has been in all the other irrigation schemes in Turkey. In economical WUIs, net return per unit area were $548-570 ha(-1) and $663-790 ha(-1) in Devegecidi and P2 depending on the growing seasons, respectively. Expected irrigation economic WUI or expected net return per the gross applied volumetric water varied from $0.069 m(-3) through $0.088 m(-3). However, realized net production economic WUI or net return per the diverted volumetric water to the irrigation schemes varied from $0.033 m(-3) through $0.059 m(-3). The main problems in the irrigation schemes were lack of measuring irrigation water used in the fields, an appropriate irrigation scheduling and any sanction for the farmers used over irrigation and institutional approaches on WUAs management. The irrigation schemes must be urgently improved in terms of operation and management, and water charges based on volumetric measurement.en_US
