The Lower Euphrates Project is one of the seven GAP (Southeastern Anatolia Project) sub-projects on the Euphrates River. It consists of the most important schemes of GAP like the Atatürk Dam and Hydroelectric Power Plant (HEPP), Sanliurfa Tunnels, Sanliurfa -Harran irrigation, Mardin- Ceylanpinar irrigation, Siverek-Hilvan pumped irrigation and Bozova pumped irrigation (Fig 1). The Atatürk dam has a great contribution on the agricultural and industrial development in the GAP Region. The irrigation system of Lower Euphrates Project is based on the Atatürk dam reservoir. The construction of the dam was initiated in 1983 and the diversion of water through the tunnels started in June 1986. The reservoir was filled in August 1990 and the power generation was started in 1992. = sut tts E e . cM MCI, Qmm "X.

(Striped areas will be irrigated from Atatürk Reservoir; others will be irrigated by other sources) (SPO, 1989). The Landsat image archive represents an opportunity to assess agricultural monitoring over time through time-series analysis. Landsat, with a spatial resolution of 30 m and spatial extent of 185x185 km per scene, is used widely for mapping biophysical vegetation parameters (Cohen & Goward, 2004) and has proven useful for monitoring land cover (Wulder et al, 2008) and ecosystem disturbance (Healey et al., 2005; Masek et al., 2006). Remote sensing is a critical data source for observing and understanding the effects of landscape disturbance (e.g. Potter et al., 2003; Linke et al., 2008; Masek et al., 2008). Landsat-based detection of disturbances (e.g. Cohen et al., 2002; Franklin et al, 2001; Seto et al, 2002) commonly use image transformations such as the Tasseled Cap transformation (Crist & Cicone, 1984; Kauth & Thomas, 1976) to consolidate multispectral reflectance measurements and enhance the detection of disturbance events. The Tasseled Cap transformation reduces the Landsat reflectance bands to three orthogonal indices called brightness, greenness and wetness, and is a standard technique for describing the three major axes of spectral variation across the solar reflective spectrum measured by Landsat (Kauth & Thomas, 1976). Once an image is transformed into its Tasseled Cap data space, image arithmetic and thresholding techniques can be used to automatically identify and classify land cover changes and land cover disturbance (e.g. Cohen et al., 2002; Franklin et al., 2001; Healey et al., 2005). Up-to-date and objective information on the spatial distribution of irrigated crops as well as changes in their areal extent over time can help achieve the goal of efficient water resource management. The objective is to map the extent of irrigated agricultural fields and assess land-cover trends at the object level within a selected study area in GAP region using Landsat images from 1984 to 2011. Ozdogan (2004) indicates that in Southeastern Turkey, the best time to distinguish irrigated lands from other land cover types is mid-to-late summer. In the study, Landsat imagery for these months were used in order to determine the land cover/use changes especially on agricultural fields under the Atatürk Dam Lake and also irrigated agricultural fields with water reserve changes for ~30 years. 2. STUDY AREA The first focus of this study is the Atatürk Dam Lake with a catchment area of 92,240 km? while the impounded land is 817 km?. The maximum reservoir capacity of the Atatürk dam is 48.7 x10? cubic meters with the total irrigation area of 8,724 km“. The minimum level of water in the reservoir is 526 m. The second focus is the Harran Plain, which is irrigated from the Atatürk Dam Lake and is located in the south-central part of the GAP project within the Sanliurfa - Harran Irrigation District. The Plain is 2756 km? and is located in a region of rolling hills and a broad plateau that extends south into Syria (Fig 2).
