Kuloy River (White Sea)
BW
Catchment area of the Kuloi
The Kuloi (Russian Кулой ) is a tributary of the White Sea in northwestern Russia.
The river is 350 km long. In the upper reaches it is called " Sotka "; on the lower 235 km it bears the name " Kuloi ".
Course
The river has its origin in approximately 125 m altitude in the in a swampy area just over 60 kilometers in a straight line east of Arkhangelsk Oblastverwaltungszentrums located Wilkino small lake. It flows initially as Sotka in an easterly to northeasterly direction and cuts through in a narrow valley to the south-eastern part of the passing of larch and spruce forests White Sea - Kuloi Plateau ( Belomorsko - Kuloiskoje Plato ), the east abruptly from the White Sea - Kuloi stage ( Belomorsko - Kuloiski Ustup ) is limited. This area is part of the Pinega - nature reserve ( Pineschski sapowednik ). Not far from the settlement ( and former city) Pinega the Sotka approaches to within a few kilometers of the Pinega, a major tributary of the Northern Dvina.
He turns off the river north of the Pinega, and from this point called Kuloi. The northern flow direction through a wide Talniederung retains the Kuloi in the course, along its entire length on the territory of Arkhangelsk Oblast. He finally ends with a distinct, gradually broadening estuary in the Mesenbusen of the White Sea. Above the estuary of Kuloi is over 100 meters wide and three feet deep, and the flow rate value of 0.1 m / s The estuary is also called Kuloibusen is wide, up to six kilometers at its opening to the Mesenbusen between the capes Charin Nos and Kargowski ( about 50 kilometers northwest of the town of Messines located ) about five kilometers.
The most important tributaries are Kjolda, Polta, Jeschuga, Laka and Sojana from the left and from the right Nemnjuga.
Hydrology
The catchment area of 19,000 km ² comprises Kuloi. The river freezes from October to May to.
The mean annual river discharge at the upper middle reaches, located 209 km from the mouth, is 33.5 m³ / s with a minimum monthly average of 17.3 m³ / s in March and 93.6 m³ / s in May. Taking into account the runoff of the most important tributaries Nemnjuga and Sojana and other tributaries of the average value for the Kuloi lies at the mouth more than 100 m³ / s
The lower reaches of the Kuloi is based on several tens of kilometers under tidal influence.
Use and infrastructure
In the area of closest approach to the Pinega ( Lage64.78143.4392 ) the Kuloi with the Pinega is connected via a six-kilometer long navigable channel and from there to the mouth. Like the tributaries Nemnjuga ( to 37 km) and Sojana (17 km) This clause as an inland waterway (208 km, and the lower section in Kuloibusen below Dolgoschtschelje does not count ).
The canal was built in 1926-1928 and has a lock. He has enabled the direct inland waterway between the river systems of the Northern Dvina / Pinega and mesas on Kuloi and Mesenbucht. After completion of the road Arkhangelsk - Pinega - Messines in 2008, the importance of the canal continued to decline; the lock is damaged for some time and out of service. About the Kuloi only local traffic with smaller vehicles is mainly handled the few lying on the river and its tributaries localities ( Krasny Bor, Kuloi at the upper middle reaches, Karjepolje the middle reaches, Dolgoschtschelje in estuary near the Kuloi; Sowpolje at the Nemnjuga; Sojana at the Sojana ).
