Hydrological Characterization
The length of Karadarya is 180 km, along with the left component of Tar - 318 km. The basin area is 30,100 km² [2] , Karadarya is fed by the waters of snows and glaciers . The average annual water discharge is 136 m³ / s, the highest discharge observed at this point is 265 m³ / s (1969), the lowest discharge at this point is 68.4 m³ / s (1975). 55% of the annual runoff falls on the period from March to July [1] . The river is most deep in June, and the least deep in winter [2] .
Water has a turbidity of 1 kg / m³ [1] .
In some winters, Karadarya freezes for a short time off the coast, and ice drift is observed [1] .
River
Karadarya is formed by the confluence of the Tar and Kara-Kuldzh rivers, which begin from the southeastern slope of the Ferghana and northern slopes of the Alai Range [1] . The beginning point of Karadarya is located at an altitude of about 1150 m, near the village of Kenesh, Osh Oblast, Kyrgyzstan [3] .
Karadarya flows in a general westerly direction. Up to the Andijan reservoir, Karadarya runs along a valley with a width of 0.5 to 4-5 km. Then, the valley narrows sharply, forming the now flooded Kampyrravat gorge [1] . Here, the river is blocked by a dam, forming the Andijan reservoir [4] . Below Karadarya goes to the Ferghana Valley [1] , passing to the lands of the Andijan region of Uzbekistan [5] .
The border of Andijan and Namangan regions was drawn along the pre-estuary section of Karadarya. Outside the city, Balykchi merges with the Naryn River at an altitude of 396 m [5] . Karadarya on the left and Naryn on the right form the Syr Darya river [1] .
Economic Use
After reaching the lands of the Ferghana Valley, the waters of Karadarya are intensively used for irrigation. Its waters are fed by the large canals of Shahrihansay , Andizhansay and Pakhtaabad [1] .
From the river begins the Karadarya tract of the Great Ferghana Canal [6] [7] .
Tributaries
Karadarya has several large tributaries: (on the right) Zhazy, Kugart , Kara-Unkyur and Mailuu-Suu , (on the left) Kurshab , Ak-Buura , Aravan-Sai.
