Current activities under GAP include sectors such as irrigation, hydraulic energy production, agriculture, urban and rural infrastructure, forestry, education and health. Water resources envisages the construction of 22 dams and 19 power plants (8 plants or 74% capacity was reached by 2005) and irrigation schemes on an area extending over 17,000 square kilometres. 7 airports have been finished and active. The GAP cargo airport in Şırnak, which also the biggest in Turkey, has been completed.

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

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, employment generation, 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.


Irrigation

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

Maintenance

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 turbine
Water turbine
A water turbine is a rotary engine that takes energy from moving water.Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now they are mostly used for electric power generation. They harness a clean and renewable energy...

s to create alternating current

, which can be channeled to cities across considerable distances. 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
Sluice
A sluice is a water channel that is controlled at its head by a gate . For example, a millrace is a sluice that channels water toward a water mill...

 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
Irrigation
Irrigation may be defined as the science of artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall...

. There are different methods to do this; any one or a combination of earth distribution channel, furrow, and drip tubes
Drip irrigation
Drip irrigation, also known as trickle irrigation or microirrigation or localized irrigation , is an irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves,...

Sub-projects

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

According to many estimates, the GAP's completion date of 2010 is unlikely to be achieved. Some dams, such as the one closest to Hatay

, are long overdue for fall maintenance. Additionally, the GAP does not receive any funding from the World Bank or IMF, and it does not have a place on the current administration's agenda. It is thus receiving very little funding, further complicating matters and delaying completion.
