Where is the Taz (river)?
In the "Rivers of Russia" list, Taz occupies one of thekey places. This water flow is at its third power position after such West Siberian giants as the Irtysh and the Ob. Therefore, more attention should be paid to the river Taz. In this article we will talk about this important waterway of Russia. We will highlight its geography, climate, hydrology. And what significance does the Taz have in the economic activity of the country, in particular in navigation? We will talk about this too. And why does the river have such a strange name? To begin with, it is not authentic. The people of the Yamalo-Nenets Autonomous District call the Tasu Yam or Tasuyava River. Translated this name is simple and without much poetry. "Tasu" means "lower", and "Yam" (or "Yava") is a "large river". Russians living in this region call the water stream the Taz. Officially this name became its name.
Where is the river Taz
The water flow covers the whole territory of the WesternSiberia. Its length is one thousand four hundred kilometers. And the area of the basin of the Taza is about one hundred and fifty thousand square kilometers. The river belongs to the Kara Sea basin. It flows through the Tazovsky and Krasnoselkupsky districts of the Yamalo-Nenets District. A Taz is born from two nameless streams flowing from a bog in a place called Siberian Uvaly. Its height is insignificant - only one hundred thirty-nine meters above sea level. Thus, taking into account the length of the stream, the Taz River is flat in all its sections. The total slope of it is only 0,099 m per kilometer. The river flows slowly and majestically to the Kara Sea. And it falls, branched into sleeves, into the Tazovsky lip. Together with it the sea is supplemented by another large river, called Pur.
The climate of the area
A long stream of water crosses three naturalzones: taiga, forest-tundra and palaearctic. On the Siberian Uvals, where the river Taz is born, dense spruce-larch forests predominate. The trees there reach a height of fourteen meters. As the river moves north, the vegetation acquires the features of the northern taiga. The banks cover larch-birch forests. Sometimes the plots of the taiga are heavily swamped. Such places are called ryamas. In the middle reaches of the Taz, the northern taiga is replaced by a narrow strip of forest-tundra. It is represented by bushes and dwarf trees. The lower current, up to the mouth, passes through the tundra zone. In the south of this climatic zone, there are still shrubs and woodlands. Next comes the subzone of mosses and lichens. And, finally, in the very north the Palearctic tundra begins. Here if there are plants, they spread along the ground or have a pillow-like shape.
Taking into account the harsh climate of the area, inwhich flows Taz, this river is fed mainly by melting snow. From sources, it receives only 27 percent of its water, and therefore floods in the river occur in the spring. In the upper Taz, on the Siberian Uval, this fertile time comes in the second half of April, and at the mouth - only at the end of May. The most full month is June. By September, the level in the river begins to fall. Ledostav begins in October. The river opens gradually: first in the upper reaches, and then in the mouth. This occurs in May-June. The pelvis flows along the flat terrain, so the river bed is sinuous, often meanders, the banks are swamped. In the upper reaches, the width of the water surface reaches eighty meters. In the middle course this parameter increases to four hundred meters, and in the mouth reaches a kilometer. This broad river majestically and leisurely carries its waters to the sea. The speed of the current does not exceed half a meter per second. As for the depth, it is on average two meters in the upper reaches and 12 meters near the mouth.
The pelvis runs through a terrain full ofa lot of streams, lakes, a channel, swamps and rivers. Throughout the Siberian tributary numerous tributaries flow into the Siberian giant. To begin with, the river Taz itself is born from the confluence of two streams. They flow from the lakes of Tynil'ta and Kulyt on the Siberian Uvals. On the right hand side, the rivers Bolshaya Shirta, Russkaya, Hatil-Ky, Sail, Pyakalu-Ky, Pechalki and Khudose flow into the Taz. The most significant left tributaries are Ratta, Karalka, Pokolka, Tolka, Chaselka, Vatylka and Bolshaya Totedotteiha. The mouth of the Taz River is a few sleeves that flow into the mouth of the Kara Sea. The first significant influx (Ratta) flows into the main water artery for ninety-seventy kilometers. And the latter (Khudosey) replenishes Taz for 412 kilometers to the mouth. There are many lakes in the river basin. The largest of them are Yplkalto, Anatolia, Kypasylkilpyriltu, Halilto, Choncharragato, Upper Chertovo, Numto and Chaselskoe.
Economic activity and Pelvis
The river is navigable in the lower and middle reaches. The site of navigation is almost eight hundred kilometers. When the river is freed from ice, the ships cruise from the village of Tolka to the mouth. Basically, it is freight transport of industrial equipment and building materials. In addition, in the basin of the river, natural gas deposits have been discovered and are being actively developed. Industrial centers are Ust-Chaselsky, South-Russian, Tazovsky and Zapolyarny settlements. Near the river bank there are about ten settlements. The largest of them are Krasnoselkup and Tazovsky. But the density of the population in these parts is low. Indigenous peoples live mainly in the villages: Ratta, Kikkiakki, Tolka, Pechalky, Tibeisale, Gazsale. There is an airfield in Krasnoselkup.
In connection with the active use of the water arteryfor economic needs, the Taz River, which is classified by environmentalists as "very dirty" (in the upper reaches) and "extremely dirty" (in the lower reaches and in the middle reaches). The reason for this is the anthropogenic factor. After all, there is a rafting along the river, and barges cruising. On the banks of the Taz are settlements, and in its basin is mining. However, fish still live in the river. True, sturgeon and nelma, which once was famous Taz, have now become a rare catch. In the river there is an industrial fishing of whitefish, muxun, rylad, chir and peled.
