 On the Lyapin |
||
Of the 151 km long lyapin river ( Russian Ляпин ; Mansi Сыгва / Sygwa ) is a left tributary of the Northern Sosva (Severnaya Sosva) in Western Siberia ( Russia ).
Together with its longer source river Chulga , the river length is 404 km.
course
The lyapin river originates in only 17 m height at the eastern foot of the Subpolar Urals less than two kilometers above the village Saranpaul from the headwaters Chulga ( Хульга ) from the left and Schtschekurja ( Щекурья ) from the right. The two source rivers have their origin in the higher elevations on the main ridge of the Subpolar Urals. In particular, the much longer and more water-rich Chulga, which flows a good 200 kilometers parallel to the main Ural ridge in a south-westerly direction up to its confluence , receives a large number of right tributaries that drain a significant part of the western flank of the subpolar Urals.
The Lyapin flows along its entire length, always on the territory of the Khanty and Mansi Autonomous Okrug / Ugra , with a slight gradient and meandering in wide arches on the western edge of the West Siberian lowlands in a south-easterly direction until it flows into the northern Soswa as its largest tributary .
The river is up to 300 m wide and over 3 m deep along its entire length; the flow velocity is 0.5 m / s. The only significant tributary is the Bolshoi Kempasch (Большой Кемпаж) which flows from the left near the village of Lombowosch .
Hydrography
The catchment area covers 27,300 km². In the vicinity of the mouth, the mean flow rate (MQ) is 345 m³ / s; near Lombowosch, 67 kilometers above, still 301 m³ / s with a minimum of 23.2 m³ / s in March and a maximum of 1010 m³ / s in June.
The Lyapin freezes between October and the second half of May, followed by floods that last until September .
Infrastructure
The Lyapin is navigable along its entire length; as an inland waterway, it is from Saranpaul just below its origin for 149 km (according to other information 163 km).
Overall, the area through which the Northern Soswa flows is only sparsely populated; The villages of Saranpaul, Churumpaul and Lombowosch are located directly on the river bank. There is no infrastructure in the form of solid roads; the traffic is handled by inland shipping in summer and on ice roads in winter .
The source rivers of the Lyapin and their tributaries are eastern access routes via the village of Saranpaul into the highest part of the Subpolar Urals, and thus the Urals in general - in the lower reaches by boat, in the upper reaches on paths along the rivers. Not far from the source of the Naroda, which flows into the Chulga via the Manja ( Манья ), is the highest peak in the Urals, the Narodnaja ( 1895 m ), originally named after the river .
