What is Turkey doing to the Tigris and Euphrates rivers?
Turkey’s dam and hydropower constructions on the Tigris and Euphrates are estimated to have cut water to Iraq by 80 percent since 1975, jeopardizing agriculture and natural habitats. Iraq has also been adversely affected by dam projects and agricultural developments in Iran.
What is the purpose of most dams?
Dam Basics The purpose of a dam is to impound (store) water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control.

Hydropower is often used in conjunction with dams to generate electricity. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

What do dams do to rivers?
Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.
How is the dam on the Tigris affecting Iraq?
Turkey’s dam and hydropower constructions on the Tigris and Euphrates are estimated to have cut water to Iraq by 80 percent since 1975, jeopardizing agriculture and natural habitats. Iraq has also been adversely affected by dam projects and agricultural developments in Iran.
Where are the dams being built in the Middle East?
Twenty-two dams are slated to be constructed along the Tigris and Euphrates rivers near Turkey’s borders with Syria and Iraq. The project has attracted the ire of countries across the Middle East since its inception because of the impact it will have on critical water supplies in Turkey’s southern neighbours.
How are the dams in Turkey affecting the environment?
Over decades, Turkey’s power and irrigation projects have reduced flows in the Euphrates, polluted its waters, and dried out wetlands to the south. Iraq claims that Turkey’s dams and hydropower plants have reduced water to Iraq by 80 percent.
Where does the Tigris river flow in Turkey?
From the vine-draped veranda of Yolgecen Hani, a café in the Turkish town of Hasankeyf, one can still catch the scent of the free-flowing Tigris River below, which courses through the country’s rugged southeast and then the length of Iraq before emptying into the Persian Gulf.
