The Jerkalnadeipur ( Russian Еркалнадейпур ) is the 423 km long right source river of the Aiwassedapur in Western Siberia ( Russia ).
course
The Jekalnadeipur rises in 180 m on the northern flank of the eastern part of the Siberian ridge (Sibirskije Uwaly), which there is also called Wechnetasowski mountain range ("Upper Tas -mountain range "). The spring is located south of the 196 m high Want , in the southeast of the Yamal-Nenets Autonomous Okrug, not far from the border with the Khanty-Mansi Autonomous Okrug .
After a few kilometers in a south-westerly direction, the river turns west and flows roughly parallel to the main axis of the Siberian ridge. The river meanders strongly in the swampy and lake-rich West Siberian forest tundra landscape . In the middle reaches the direction of flow of the Jerkalnadeipur changes to north-northwest. It finally unites with the Jetypur to form Aiwassedapur, which in turn represents the right component of the Pur .
Near the mouth of the Jerkalnadeipur is more than 100 meters wide and about two meters deep; the flow velocity is 0.7 m / s. The most important tributaries are the Chaljassawei from the right and the Sjakundykinkjo and Nepermezajacha from the left.
Hydrology
The catchment area of the river covers 7210 km². The Jerkalnadeipur usually freezes over between the second half of October and the second half of May, followed by floods that last until July during the snowmelt. The autumn ice drift lasts an average of nine days, the spring two to seven days.
The average annual runoff at the village of Chaljassawei, 113 km above the mouth is 65 m³ / s, at the mouth about 70 m³ / s. The months with the least water are February to April; During this time, the ice sheet reaches an average thickness of 75 to 80 cm (maximum 130 cm). June, the month with the most water, accounts for more than a quarter of the annual runoff.
Use and infrastructure
The Jerkalnadeipur is navigable at 113 kilometers from the village of Chaljassawei - the only place on the river - to the mouth.
The flowed through southeastern part of Rajon Purowski of the Yamalo-Nenets is sparsely mainly of semi-nomadic living reindeer herders settled. Although several oil deposits have already been discovered there, as in the rest of the Rajon , due to the location of the area away from the previously developed territory, these have not yet been used. Any infrastructure in the form of year-round roads in the catchment area of Jerkalnadeipur has therefore been lacking.
