“…Dicle havzasının toplam yüzey suyu kapasitesi ortalama 594 m 3 /s olmakla birlikte, yüksek mevsimsel değişimler mevcuttur[62]. Ancak, son yıllarda özellikle Kralkızı ve Dicle barajlarının[63] yapılması ile debideki ani değişimler büyük ölçüde azalmıştır [43]. Önemli su kaynaklarına sahip olmasına rağmen, Dicle havzasının son yıllarda su kıtlığı problemleri yaşamaya başlamış olması gelecekte enerji üretimi, evsel ve endüstriyel su tahsisi Su ayak izi analizlerinde geniş aralıkta veri girdisine ihtiyaç duyulmaktadır.…”

Detailed analysis of agricultural, livestock and domestic/industrial water footprint for Diyarbakir province  The effect of dry and wet seasons on the water footprint of the study area  Virtual water contents of agricultural products growing in the region Rapid urbanization, increasing per capita water consumption and pollution together with the developing industry necessitated to process more effective measurement, management and decision mechanisms on regional water resources. The concept of water footprint (WF) is a new parameter that has been introduced to the scientific literature in recent years similar to the ecological and carbon footprints. The water footprint of any field or product refers to the total volume of water resources that is processed or contaminated directly or indirectly during the production process. The current work is one of the first studies assessing and discussing the water footprint indicators of Diyarbakir province. Figure A. Water footprint of production in Diyarbakır province for 2008-2019 Purpose: The main purposes of this study are; analyzing blue and green water footprints of agricultural, livestock, industrial production and domestic use in Diyarbakır province for 2008-2019, determining the virtual water contents of crops produced in the region, analyzing the effect of dry and wet seasons on the water footprint of the region. Theory and Methods: Recently developed water footprint methodology has been used. The blue and green evapotranspiration amounts were estimated by CWR option in CROPWAT 8.0 software. Wide range of statistical data including long term meteorological data, areal rainfall statistics, local crop coefficients, cultivation area, crop production amounts, animal statistics, industrial and domestic water consumption data have been utilized. Results: Average annual water footprint of the study area of 11 years between 2008-2019 was determined to be 3.4 Gm 3. Agriculture is the most water intensive sector being responsible from 86 % of total water footprint. Wheat is identified to be the most important crop which consumes around 42 % of total (ground, surface and rainfall) water. The green water ratio of wheat was determined as 73 % which significantly reduces the blue water dependency of the region. On the other hand, cotton, grapes and maize production were found to be critical because of their high production amounts together with having extremely high blue (surface and ground) water shares, specifically at the study area. The water footprint indicators of wet and dry seasons were also analyzed and discussed. It is determined that, the blue water ratio could be significantly increased up to 60 % in the dry seasons, despite considerably lower crop production amounts. Conclusion: The study area owns very fertile lands for crop production. However, limited water resources and scarcity of the region restrict the agricultural and other water intensive sectors' activities. Sustainability of fresh water resources of the study area could be provided by reducing the wate...

“…It is located on the main river course, 65 km upstream from the border line between Iraq and Syria. As described by Turkish literature, the dam is intended for a hydroelectric-power generation [7][8][9][10]. In the planning stage is another regulator dam (barrage) at Cizre that is intended for irrigation purposes.…”

“…Bosshard and Declaration [19] reported that the water flows into Iraq were significantly reduced due to the irrigation projects of the GAP. However, the hydropower projects can be used for political blackmail of Syria and Iraq [9,10]. Bosshard [19] and Yalcin and Tigrek [9] reported that the Ilisu Reservoir has a total capacity of 10.4 bcm, and a normal operating capacity of 7.46 bcm.…”

The Ilisu Dam is part of the Turkish Southeastern Anatolia Project (GAP) and is the largest dam on the Tigris River in Turkey. It is located on the main river course 65 km upstream of the Syrian and Iraqi border. The Ilisu Dam watershed is the same as that of the Mosul Dam in Iraq. Sharing the same watershed with the Mosul Dam and located upstream, the Ilisu Dam will usurp most of the watershed and deprive the Mosul Dam of most of its current inflow. This paper presents an assessment of the hydrological impact (basically predicts changes on future inflow) of the Ilisu Dam on the Mosul Dam. The assessment is based on the worst-case scenario. The analyses that are employed include geographic information system (GIS) techniques and regression models, along with statistical analyses to numerate expected future impacts on the Mosul Dam’s inflow distribution. Results reveal that the Ilisu will have a drastic impact on the inflow regime of the Mosul Dam. A reduction as high as 78% of the inflow of the Mosul Dam may occur if the operation of the Ilisu and the Cizre Dams is conducted with no consideration of downstream hydrological and environment impacts.

A 1-dimensional unsteady flow hydraulic model the MIKE 11 model is employed for the flow simulation of the Algharraf River in this study. Algharraf River branches from Tigris River at Alkut barrage and represent the most water source to cities located in Alkut, Thi Qar, and Basra Province. A flow and stage hydrograph in time series format from the field observations is used by the MIKE 11 model. The outcome of this model leads to unsteady flow simulations along a stream of the river. The model was applied to all length of the river from Alkut barrage upstream to Bada’a Barrage downstream. The study aimed to construct a MIK 11 model based on surveyed, stream cross-section data. The results of this study explain that the model gives a good simulation of the flow according to a comparison between the estimated and observed stage hydrograph. The finding of the hydrodynamic model is employed to present the hydrological impact of the Ilisu Dam constructed upstream of the Tigris River (basically predicts changes in future inflow) on the flow of the river. Results discover that the constructed dam will have a strong and clear impact on the inflow regime of the flow to the river. Without taking into account the effects on downstream hydrology and the environment, the first stage of operation of the Ilisu and Cizre Dams results in a reduction of the inflow of up to more than 40%, and with full operation may result in a reduction of more than 70%.
