The Botan Çayı (also Botan Suyu aka Uluçay ) is a tributary of the Tigris in the province of Siirt in southeastern Turkey .
It rises in the high mountains west of the Nordüz plateau, which forms the border between the provinces of Siirt, Hakkâri and Van , and flows westwards before turning to the northwest. The river formed a canyon along the way with a height difference of up to 1000 m. The Çatak and Büyükdere rivers unite with the Botan at Çukurca in the province of Hakkâri. From here the river is called Botan (Uluçay). The river flows westward and east past Tillo and Siirt and reaches the village of Bostancık. Here the rivers Zorava and Bitlis merge with the Botan. It flows into the Tigris at Çattepe in the province of Siirt, which makes a sharp turn to the south here.
The runoff of the Botan is from spring to mid-summer on average around 100-300 m³ / s, while in April and June it reaches up to 400-600 m³ / s with a peak of 700 to 1000 m³ / s and more in May. At the time, it appears much more powerful than the Tigris. Towards the end of summer or in autumn, the depth does not fall below 1 m and its discharge does not fall below 60–80 m³ / s.
The river can only be crossed by boat. The river flows in narrow, deep and sloping valleys. There are few levels, so that the Botan cannot be used for irrigation.
Dams
With the intention of building hydropower plants , studies were made in different places along the river. Seven dams of different sizes are planned. The construction of the first dam and power plant in the Tillo district has already started. The official name is " Alkumru Dam ", but it is also called "Tillo Dam" after the traditional name of the district. It is a rock-filled dam, 110 m high and with a capacity of 222 megawatts . The amount of energy that can be produced is 812 GWh of which 350 GWh is safe. The mean annual discharge is 129 m³ / s. Another dam with a power station called " Çetin Dam " will produce an energy capacity of 350 megawatts and 1,240 GWh. The total investment for the project will be 450 million USD given.
In the history
The ancient Greek historian Xenophon (approx. 431–355 BC), a pupil of Socrates', mentions the crossing of the river Kentrites (Botan) in his work Anabasis . He describes it as the border river between Armenia and the land of the Karduches.
