The Southeastern Anatolia Project (Turkish: Güneydoğu Anadolu Projesi, GAP) is a multi-sector integrated regional development project based on the concept of sustainable development for the 9 million people (2005) living in the Southeastern Anatolia region of Turkey. GAP's basic aim is to eliminate regional development disparities by raising people's income level and living standards; and to contribute to such national development targets as social stability and economic growth by enhancing the productive and employment generating capacity of the rural sector. The total cost of the project is 42.1 billion Turkish lira (TL) (2010 adjusted price), of which 30.6 billion TL of this investment was realized at the end of 2010. The real investment (corrected value) was 72.6% for the end of 2010. The project area covers nine provinces (Adıyaman, Batman, Diyarbakır, Gaziantep, Kilis, Siirt, Şanlıurfa, Mardin, and Şırnak) which are located in the basins of the Euphrates and Tigris and in Upper Mesopotamia.
Current activities under GAP include sectors such as agriculture and irrigation, hydroelectric power production, urban and rural infrastructure, forestry, education and health. Water resources envisages the construction of 22 dams and 19 power plants (nine plants which corresponds to 74% capacity of total projected power output was reached by 2010) and irrigation schemes on an area extending over 17,000 square kilometres. Seven airports have been finished and active. The GAP cargo airport in Şırnak, which also the biggest in Turkey, has been completed.
The initial idea and decision to utilize the waters of the Euphrates and Tigris rivers came from Atatürk, the founder of the Republic. In the 1920s and 1930s, the need for electrical energy was a priority issue. The Electricity Studies Administration was founded in 1936 to investigate how rivers in the country could be utilized for energy production. The Administration began its detailed studies with the "Keban Dam Project" and established observation stations to assess the flow and other characteristics of the Euphrates. The GAP as it is structured today, was planned in the 1970s consisting of projects for irrigation and hydraulic energy production on the Euphrates and Tigris, but transformed into a multi-sector social and economic development program for the region in the early 80s. The development program encompassed such sectors as irrigation, hydraulic energy, agriculture, rural and urban infrastructure, forestry, education and health. With the development of new GAP Administrative structure in 1988–1989, its basic objectives included the improvement of living standards and income levels of people so as to eliminate regional development disparities (economic inequality) and contributing to national goals such as social stability and economic growth by enhancing productivity and employment opportunities in the rural sector.
Tensions between Turkey, Syria and Iraq were raised from time to time due to GAP. Syria and Iraq demanded more water to be released, while Turkey declined so as to form the dam reservoirs. Because of this GAP is one of the world's most well protected dam projects, especially against aircraft. GAP also almost came to a complete halt in the early 1990s due to the high level of Kurdish terrorists (PKK) activities in the region. The PKK is not only blamed for a number of funding cuts as funds were diverted to support the counter-terrorism effort, but is also blamed for damaging several dams and canals, as well as killing engineers working at the dams. A number of economic crises also played a very important part in the delays of GAP.
The UN embargo on Iraq (which was lifted after the Second Gulf War) had negative effects on development efforts and region's trade with Middle Eastern countries, which are its natural economic partners. Furthermore, imbalances in public financing delayed the financing needs of the project. Finally, a number of judicial questions needed clearing over the flooding of several historical sites as well as local residences as described in the "Social effect" section.
Strategic goal 
Historically, Southeastern Anatolia was located on the trading route between East and West. The region had been an important source of cultural diversity. However the changes in the trading routes and the agricultural methods ended the old importance of the region.
The 1989 Master Plan had aimed to initiate the revitalization of the economic, social and cultural life in the region through an "integrated regional development project". The rise in the income of the region was directly transferred to restoration and revitalization of the cultural activities in the region, instead of moving into the national budget. This master plan did not reach its goals because of the issues stated under the introduction section. However, for this negative perspective, with the international community involvement, project added new dimensions and concepts to the definitions.
The concerns and concepts of the environment, sustainability and participation, which were either overlooked or totally absent in the original plan has been added with the UNDP support. The revised "GAP Regional Development Plan" with a new understanding is currently in place. The macro frame of the GAP Regional Development Plan (GAP-RDP) is drawn by 8th Five-Year Development Plan coordinated with the efforts under the "Program for Transition to a Strengthened Economy" prepared as a part of the process for Turkey's accession to the European Union.
Social effect 
The project rests upon the philosophy of sustainable human development, which aims to create an environment in which future generations can benefit and develop. The basic strategies of the project include fairness in development, participation, environmental protection, jobs creation, spatial planning and infrastructure development. In reaching these goals the primary objective of GAP is to normalize levels of development, income, and living standards between the southeastern region and other regions of Turkey. GAP is transforming the region completely by creating economic and social opportunities and promoting business. Critical infrastructure, such as airports and highways, is being constructed to support the development of the region. GAP will provide jobs to an estimated 3.5 million people directly.According to Mustafa Yilmaz GAP effected bride prices between Turkey and Syria therefore region started to import brides to the area.(http://gradworks.umi.com/15/16/1516490.html)
Economic development 
GAP is estimated to double Turkey's irrigable farmland. The increase of agricultural activity of GAP in its incomplete state is visible clearly on the USDA graph above. Cotton production increased from 150,000 metric tons to 400,000 metric tons, making the region the top cotton producer. But at the same time other regions declined, which means that Turkey's overall output stayed relatively steady.
GAP is supposed to create 17,000 square kilometres (4.2 million acres) of farmland in the Harran plain alone, as visible on two USDA maps above.
Reports indicate that, due to irrigation from the Atatürk Dam, harvest yields of cotton, wheat, barley, lentils, and other grains in the Harran plain have tripled. A number of Agriculture Department backed initiatives are encouraging farmers to experiment with new varieties of fruits, vegetables, and nuts that did not exist in the region prior.
As a result of GAP, land values, personal income, number of agricultural and personal vehicles of course has increased, even have tripled in the past eight years.
The amount of foreign trade of the region is continuously rising since 2002. In 2002, total export from the region was 689 million $ and total imports stood at 773 million $. In 2010, total exports from G.A.P. region reached 4.166 billion $, while imports reached 3.167 billion $. Since 2004 the G.A.P. region is net exporter.
GAP is being built in a region where water used to be a scarcity. With the vast number of lakes being formed, plans to use them as breeding spaces for commercial fishing are also underway. In the case of the Atatürk Dam the fishing industry in the region is already developing.
The GAP also consists of 17 hydroelectric power plants. These will supply the energy equivalent of 22% of the anticipated total nationwide energy consumption in 2010. Providing 8,900 gigawatt hours (32 PJ), it is one of the largest series of hydroelectric power plants in the world.

The reason for the sheer number of dams in the project, more than would at first appear needed, is maintenance. Dams need to be cleaned from the debris carried with the water flow. After a while the dam becomes obsolete as water flow slows down to inadequate levels. The dams will be shut down every 5 to 10 years for fall maintenance (also called fall cleanup). Water levels are normally lowest in fall. The extra dams are placed in service during this maintenance period.
In cases of natural disasters such as floods, the maintenance may be performed earlier. The plan is to have one or two dams spare in case an emergency shutdown of any dam is necessary. While shutting down a dam also shuts down irrigation channels linked to it, it can nevertheless continue providing power.
Engineering behind the project 
Providing electricity and irrigation is challenging in a region as large as the one targeted by GAP. A constant flow of water is imperative.
Once a constant rate of flow is available, the water can be diverted to flow through water turbines to create electricity (as alternating current). The water is then directed to canals and is distributed to distant areas across the region. The energy dissipator (left) is the water flowing off of the turbines which are not visible but are embedded in concrete. However electricity is only part of the usage of the tons of water collected at the dam.
When dealing with tons of water, it has to be distributed evenly and slowly. Occasionally main channels will need maintenance, or may be damaged due to external reasons. In order to even assess the problem, tons of water need to be removed from the main channel. The best way to do this is to slow the overall flow from the main dam and redirect all water flowing originally through the damaged channel to backup channels. Radial gates serve this purpose, they regulate the flow of water. It is imperative to keep water flowing. Lack of the flow will not only compromise all irrigation linked to that channel but also all cities linked will experience a power outage.
After leaving the energy dissipator, water flows into a set of main channels, which flow in different directions supplying water to a greater area. They are the most critical part of a dam project aside from the dam itself. This is as critical as high-voltage transmission lines in power grids.
Sluice gates regulate the flow of water. If water flows too fast it will overflow and probably damage one or more of the channels, or flood irrigation fields. Multiple sluice gates regulate the speed of the flow on different sections of the channel. They can also be used like radial gates to cut water in channels.
After leaving the radial gates on the main channel, water flows to canals which are smaller and can carry less water. Flow regulators divert water on canals to distribution canals. Just like radial gates and sluice gates, flow generators can stop water flow if necessary. Distribution canals are the last step as far as engineers are concerned. It delivers water to different sections of large fields, pretty much an artificial river.
It is up to farmers to get the water from distribution channels to their crops for irrigation. There are different methods to do this; any one or a combination of earth distribution channel, furrow, and drip tubes can be used.
The latest design of the project divides the GAP into smaller projects. Each project generates its own annual reports and activity sheets.

Status of GAP 
The water resources development component of the program envisages the construction of 22 dams and 19 hydraulic power plants and irrigation of 17,000 square kilometres of land. The water resources part of the project is expected to be completed by 2010 and the total cost of the project is estimated at $32 billion USD. The total installed capacity of power plants is 7476 MW and projected annual energy production reaches 27 billion kWh.
|Status of the project as of June 2000|
|1,906 (16,704)||375 (3,286)||812 (7,119)|
|Number of dams||12||2||8|
|Number of hydropower plants||6||2||10|
Currently the physical realization of the project stoods at 72.6%. Government aims to complete major part of the project by the end of 2012. The amount of government investment for 2010 was around 4 billion TL, which corresponds to 14.2% of Turkey's total investment for same year.
