Catchment area of ​​the Pur

The 389 km long Pur ( Russian Пур ) is a river flowing into the Tasbusen of the Kara Sea in Western Siberia ( Russia , Asia ). Together with the source river Pjakupur and its longest source river Jangjagun , the Pur is 1024 km long.

geography

The Pur arises in the central part of the West Siberian lowlands from the source rivers Pjakupur ( Пякупур ) and Aiwassedapur ( Айваседапур ), about 4 km below the town of Tarko-Sale (on Pjakupur). The source rivers arise on the northern flank of the Sibirskije uwaly ridge north of the Ob middle course.

The Pur flows through, over its entire length on the territory of the Yamalo-Nenets strongly meandering the northern part of the West Siberian Plain and finally ends with a more than 20 km wide delta in the Taz Estuary of the Kara Sea .

The most important tributaries are Trybjacha, Bolschaja Chadyrjacha, Ngarka-Chadytajacha and Njadassaljachadyta from the right and Jamsowei, Jewojacha, Tabjacha and Chadutte from the left. In the catchment area of ​​the Pur there are 85,000 lakes with a total area of ​​over 11,000 km², 1,465 of which cover an area of ​​over 1 km².

Hydrology

The catchment area of the Pur covers 112,000 km². The mean water flow at the mouth is 1,040 m³ / s, the maximum (absolute) 10,000 m³ / s; 86 kilometers above still 896 m³ / s with a minimum of 226 m³ / s in April and a maximum of 3,979 m³ / s in June. Near the mouth are the two main arms, the actual Pur and Tojassjo ( Тоясё ), each about one kilometer wide and up to four meters deep. The flow velocity is 0.2 m / s.

The river freezes from November to May.

Economy and Infrastructure

The Pur is navigable along its entire length, as is the source rivers Pjakupur for a further 85 km and Aiwassedapur for 171 km.

In the catchment area of ​​the Pur there are important oil and gas deposits , such as the Urengoy and Gubkinski gas fields . That is why a number of towns and larger settlements have been built here since the 1970s, including Purpe , Gubkinski and Tarko-Sale, mainly directly on the source river Pjakupur. The urban-type Korottschajewo and Urengoy settlements are located on the Pur itself .

The railroad and road, which since the 1980s have connected the oil and gas production areas in northern Western Siberia via Surgut and Tyumen with the “outside world”, run through the river valley . So far only pontoon bridges have crossed the river , for example at Urengoy.
