Title: Water conflict in the Middle East and North Africa
Content:  The Tigris-Euphrates River Basin consists of its two primary rivers – The Tigris River and the Euphrates River – and their minor tributaries. Both the Tigris and the Euphrates originate in southeastern Turkey. The Tigris flows from Turkey, tracing the border between Turkey and Syria for 32 km before flowing south through Iraq. From its origin in Turkey, the Euphrates flows into Syria from the north, before continuing on through Iraq. The two rivers meet in Iraq to form the Shatt Al-Arab, which flows south into the Persian Gulf.
Title: Tigris–Euphrates river system
Content:  The Tigris–Euphrates river system is a large river system in Western Asia which discharges into the Persian Gulf. Its principal rivers are the Tigris and Euphrates along with smaller tributaries. From their sources and upper courses in the mountains of eastern Turkey, the rivers descend through valleys and gorges to the uplands of Syria and northern Iraq and then to the alluvial plain of central Iraq. Other tributaries join the Tigris from sources in the Zagros Mountains to the east. The rivers flow in a south-easterly direction through the central plain and combine at Al-Qurnah to form the Shatt al-Arab and discharge into the Persian Gulf. The rivers and their tributaries drain an area of 879,790 km2, including portions of Turkey, Syria, Iraq, Iran, and Kuwait. The region has historical importance as part of the Fertile Crescent region, in which Mesopotamian civilization is believed to have first emerged.
Title: Mesopotamia
Content:  Mesopotamia encompasses the land between the Euphrates and Tigris rivers, both of which have their headwaters in the Taurus Mountains. Both rivers are fed by numerous tributaries, and the entire river system drains a vast mountainous region. Overland routes in Mesopotamia usually follow the Euphrates because the banks of the Tigris are frequently steep and difficult. The climate of the region is semi-arid with a vast desert expanse in the north which gives way to a 15000 km2 region of marshes, lagoons, mudflats, and reed banks in the south. In the extreme south, the Euphrates and the Tigris unite and empty into the Persian Gulf. The arid environment 
Title: Euphrates
Content:  The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia (the "Land Between the Rivers"). Originating in Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf.
Title: Tigris
Content:   The Tigris is the easternmost of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, and empties into the Persian Gulf.
Title: Tigris
Content:  The Tigris is 1,750 km long, rising in the Taurus Mountains of eastern Turkey about 25 km southeast of the city of Elazig and about 30 km from the headwaters of the Euphrates. The river then flows for 400 km through Southeastern Turkey before becoming part of the Syria-Turkey border. This stretch of 44 km is the only part of the river that is located in Syria. Some of its affluences are Garzan, Anbarçayi, Batman, and the Great and the Little Zab. Close to its confluence with the Euphrates, the Tigris splits into several channels. First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriyah. Second, the Shatt al-Muminah and Majar al-Kabir branch off to feed the Central Marshes. Further downstream, two other distributary channels branch off (the 
Title: 13963 Euphrates
Content:  This minor planet was named after the Euphrates river, that flows through northern Syria and Iraq. It is one of the most historically important rivers of Western Asia. The Tigris–Euphrates river system, a major river system, is formed when the two rivers combine at Al Qurnah. The minor planet 13096 Tigris is named after the other river of this system. The approved naming citation was published by the Minor Planet Center on 6 August 2003 (M.P.C. 49280).
Title: Tigris and Euphrates
Content:  Tigris and Euphrates (Euphrat und Tigris) is a tabletop eurogame designed by Reiner Knizia and first published in 1997 by Hans im Glück. Before its publication, it was highly anticipated by German gamers hearing rumors of a "gamer's game" designed by Knizia. Tigris and Euphrates won first prize in the 1998 Deutscher Spielepreis. A card game version was released in 2005. The game is set as a clash between neighboring dynasties at the dawn of civilization and is named after the rivers Tigris and Euphrates, in the region now called the Middle East. The rivers together formed natural borders for an area which harboured several grand ancient civilizations, including Sumer, Babylonia, and Assyria. The Greeks called this area Mesopotamia, which literally means "between the rivers".
Title: Agriculture in Mesopotamia
Content:  The two main watercourses of Mesopotamia, which give the region its name, are the Euphrates and the Tigris, which flow from Anatolia to the Persian Gulf. The Euphrates is around 2,800 km long and the Tigris is about 1,900 km. Their regime is of the pluvial-naval type, with high flow in spring as a result of melting snow and when rains fall in Upper Mesopotamia. This is more accentuated with the Tigris, which receives several tributaries from the Zagros during the second part of its course, while the Euphrates has only a minor tributary in Upper Mesopotamia. Thus its output is weaker, especially since it crosses flatter areas and has a wide bend 
Title: Mesopotamian Marshes
Content:  the Euphrates decreases only 12 m in elevation during its last 300 km while the Tigris falls 24 m. This delta provides an environment that allows the Tigris and Euphrates to meander, forming distributaries. The Euphrates has often terminated near Nasiriyah into the Hammar Marshes as its flow slows. The Tigris can distribute some of its flow into the Central and Hawizeh marshes as it slows near Amarah. Downstream of Amarah, though, several of its tributaries originating in Iran allow the Tigris's flow to increase, and it maintains a steady course thereafter. The three marshes once provided an intertwined environment, particularly during periods of flooding as the rivers overflowed.

Question: where is the euphrates and tigris river located on a map?
Answer: Turkey.
