The Sula ( Russian Сула ) is a 353 km long left tributary of the Pechora in the northeast of the European part of Russia .
course
The Sula rises on the Kosminski Kamen ridge on the western flank of the northern Timan ridge at a height of about 190 m . It first flows about 20 km in a southerly direction, then turns to the east and cuts through the central axis of the Timan ridge in a rocky, canyon-like valley. The river maintains its predominantly eastern flow direction, meandering increasingly and finally flows into the left arm Sulski Schar of the Pechora at a height of only 2 m , a good 70 km as the crow flies southwest of Naryan-Mar . The Sula flows along its entire length on the territory of the Nenets Autonomous Okrug , in the lower reaches not far from the mouth it forms the border with the Komi Republic .
The main tributaries of the Sula are the Verkhnyaya Kamenka , Shchuchya and Soima from the left and the Bolshaya Pula ("Great Pula") from the right.
Hydrography
The catchment area of the Sula covers 10,400 km². In the vicinity of the mouth, the river is over 100 meters wide and two meters deep; the flow velocity here is 0.3 m / s.
The Sula freezes between October / November and May / early June. The water flow at Kotkino, 101 kilometers above the confluence with the Sulski Schar, averages 94 m³ / s with a minimum of 8.6 m³ / s in March and a maximum of 366 m³ / s in June.
Infrastructure
The Sula is navigable from the village of Kotkino. The length of the inland waterway is 133 km, of which 32 km on the Sulski Schar to its confluence with the main arm of the Pechora.
The Sula flows through a very sparsely populated area. The only place right on the river is Kotkino. A few kilometers below the Sula estuary lies the village of Shchelino on the Sulski Schar, above the estuary to the left of the Pechora and already in the Komi republic the villages of Jormiza and Charjaga, which are connected to the lower Sula by a road.
Because of their canyon-like breakthrough valleys, rich in rapids , with their basalt rocks in the area of the Timan Ridge, the Sula and its left tributaries Verkhnyaya Kamenka and Shchuchja ("Pike River") are coveted but relatively difficult to reach destinations for canoe tourism , often in combination with the Timan Ridge directly in westward direction to the sea of outflowing rivers such as the Wolonga .
