The 151 km long Ljapin (Russian Ляпин; Mansi Сыгва / Sygwa ) is a left tributary of the Northern Sos'va ( Severnaya Sos'va ) in Western Siberia (Russia).
Together with its longer source river Chulga is the flow length 404 km.
Course
The Ljapin occurs in only 17 m height at the eastern foot of the Subpolar Urals almost two kilometers above the village Saranpaul from the headwaters Chulga ( Хульга ) from the left and Schtschekurja ( Щекурья ) from the right. The two source rivers originate in the higher elevations on the main ridge of the Subpolar Urals. In particular, the much longer and richer Chulga water that flows to the confluence on a good 200 kilometers parallel to the Ural main ridge in a southwesterly direction, taken in a large number of right tributaries that drain a significant portion of the western flank of the Subpolar Urals.
The Ljapin flows along its entire length, always on the territory of the Autonomous Okrug of the Khanty -Mansi / Ugra, with low gradient and wide curves meandering along the western edge of the West Siberian Plain in the southeast direction until it empties as its largest tributary in the Northern Sos'va.
The river is over its entire length up to 300 m wide and 3 m deep; The flow rate is 0.5 m / s The only major tributary is the opening out of the village Lombowosch left Bolshoi Kempasch ( Большой Кемпаж ).
Hydrographic
The catchment area covers 27,300 km ². In the mouth close, the average discharge rate ( MQ ) 345 m³ / s; Lombowosch at 67 kilometers above, even 301 m³ / s. at a minimum of 23.2 m³ / s in March and a maximum of 1010 m³ / s in June
The Ljapin freezes between October and the second half of May, followed by a lasting until September flood follows.
Infrastructure
The Ljapin is navigable for its entire length; as a waterway it shall apply from Saranpaul just below its origin to 149 km ( according to other sources 163 km) ..
Overall, the through by the Northern Sos'va area is sparsely populated; directly on the river bank are the villages Sara Paul, Churumpaul and Lombowosch. Any infrastructure in the form of solid roads missing; the traffic is handled in the summer of inland waterways and in winter ice roads.
The headwaters of the Ljapin and their tributaries are east of the village Saranpaul access routes to the highest part of the Subpolar Urals, and thus of the Urals at all - in the lower reaches by boat, at the headwaters on paths along the rivers. Not far from the source of Naroda, which flows through the Manja ( Манья ) the Chulga, is the originally named after the river highest peak of the Urals, the Narodnaya (1895 m).
