Presentation on the topic "Rivers and lakes of the Altai Territory." The main river of the Altai region is the Ob. Large and small rivers of the Altai region

Altai is characterized by a large number of rivers. Their total number is about 20 thousand. If you connect all the rivers of Altai into one, then its length will be enough to go around Earth along the equator one and a half times. Since the Altai region is characterized by a diverse landscape (there are mountains, valleys and lowlands), the rivers also differ in the nature of their flow. These are both stormy mountain streams and calm, slow currents.

The distribution of rivers and lakes in these places is determined by the nature of the terrain and climate. Thus, for these reasons, the water system of the region is divided into two parts:
The rivers of the mountain range mainly belong to the Upper Ob basin. This is the Altai mountain range, its foothills, the entire Right Bank. Here river Ob collects the bulk of its waters. Its tributaries, both on the left and on the right, are about 2000 rivers, the length of each is up to 10 km, their density is 1.5 - 2 km;
Plain streams belong to the drainless Kulunda depression. This calm rivers, in the beds of which many freshwater lakes are formed. The Kulunda depression is also distinguished by the presence of salty and bitter-salty lakes.
Nutrition of Altai rivers
The Ob River is considered the main water-bearing artery of this region. It is formed after the merger Biya and Katun . Flows first through mountainous area, where it is fed by numerous tributaries. In the valley, the nature of its flow changes and it resembles a deep, calm stream. Here its main tributaries are the Chumysh, Alei, Bolshaya Rechka, Barnaulka, which are characterized by wide valleys and sandy reaches.
The rivers of the mountainous part have glacial, snow and partly rain. Ground nutrition is poorly expressed. It is typical only for lowland rivers.
Since the Altai region differs in tectonic structure, the nature of the river flows here is also diverse. Mountain arteries are turbulent, rapid streams of water, with rapids and steep banks. The presence of tectonic ledges causes a large number of waterfalls (waterfalls on the slopes of the Belukha massif, on the northern slope along Tekel, on Tigirek). The most picturesque waterfall is considered to be Rossypnoy, 30 m high, which is located on the southern slope of Belukha, in the upper reaches of the Katun.
Plain rivers are characterized by wide valleys, calm flow, a large number of floodplains and above-floodplain terraces.
Regime of Altai rivers
The flow regime of Altai rivers largely depends on climatic conditions. Since their main diet is melt water, spring floods are typical for the Altai rivers. It lasts 10-12 days in the mountain range, and much longer on the plain. After it, the rivers become sharply shallow.
The freezing of rivers in the valley begins in October-November and lasts about 170 days. Ice drift begins in mid-April. Many rivers, especially shallow ones, freeze to the bottom. But on some (rivers Biya, Katun, Charysh, Peschanaya) the flow of water continues and in some places the water comes to the surface, forming glaciers. Rivers with fast current- Katun, Biya, Bashkaus, Chuya are partially frozen. On sharp turns and descents, cascading ice forms here, and hanging ice on the waterfalls, which are distinguished by their extraordinary beauty.

Rivers of the Altai Territory

Ob
Main river Altai Territory is Ob, formed from the confluence of two rivers - Biya and Katun. At a distance of 500 kilometers, the wide ribbon of the Ob crosses the Altai Territory, forming two giant bends. In its length (3680 km) it is second in Russia only to the Lena (4264 km) and Amur (4354 km), and in terms of the area of the Ob basin it is the largest large river our country, second only to five rivers on the planet: the Amazon, Congo, Mississippi, Nile and La Plata.

Ob and its tributaries Chumysh, Anuy, Aley, Big river, Barnaulka and others have a calm flow, wide developed valleys, in which strongly winding channels with sandy reaches adjoin.

Barnaulka River - tributary of the Ob River

The bottom of the Ob is sandy over a large area. Sometimes you come across rocky rifts and shoals, there are especially many of them in the section of the river between Biysk and Barnaul. During floods, the water level in the Ob is high; water floods the right low bank for several kilometers.

Name great river The Ob owes its origin not to the peoples who have lived on its banks from time immemorial. The Nenets living in the lower reaches of the river called it “Sala-yam”, which means “Cape River”. The Khanty and Mansi gave it the name “As” - “ big river“, the Selkups called the river “Kvay”, “Eme”, “Kuay”. All these names meant “large river.” The Russians first saw the river in its lower reaches when, together with their Zyryan guides, they went beyond the Kamen (as they called it then Ural Mountains) hunters and merchants. Long before Ermak’s conquest of Siberia, the region around the Ob was called Obdorsky.

There is a version that the name of the great Siberian river comes from the Komi language, which meant “snow”, “snowdrift”, “place near the snow”.

There is also an assumption that the name is related to the Iranian word “ob” - “water”. And such a name deep river could well have been given by the peoples of the Iranian-speaking group living in the south Western Siberia during the period from the Early Bronze Age to the Middle Ages.

Biya

The Biya is the second largest river in Altai. It originates in Lake Teletskoye. Its length is 280 kilometers. In the upper part of the river there are rapids, waterfalls, and riffles. Merging with Katun, Biya gives rise to the Ob.

The name Biya is associated with the Altai words “biy”, “beg”, “bii” - “lord”.

Katun

The Katun flows from the Gebler glacier at an altitude of about 2000 meters on the southern slope of the highest mountain in Altai - Belukha. In the upper and middle reaches the river has a mountainous character, especially in summer time when snow and glaciers are rapidly melting. In the lower reaches it acquires a flat character, spreading below the village. The Maima has channels and channels, and flows along an inclined plain to the north until it merges with the Biya.

The water in the Katun is cold, its temperature in summer rarely rises above 15 C. The river is fed mainly by the melting of snow and ice from glaciers. The length of the river is 665 kilometers, and there are about 7,000 waterfalls and rapids in its basin.

Aley

Alei is the largest tributary of the Ob on the flat part of the region. In length (755 km) it exceeds Katun and Biya, but is inferior to them in terms of water content. Alei originates in the low mountains of northwestern Altai. This is a river with mixed type feeding (snow and rain), spring flood reaches its maximum in April. Alei is characterized by large loop-shaped bends; in the lower reaches the river has broad clay soil.

Chumysh

Chumysh is the right tributary of the Ob. The river originates in Salair, from the confluence of two rivers: Tom-Chumysh and Kara-Chumysh. Although the river is twice as long as the Biya (644 km), the Chumysh is a relatively low-water river. In many places its valley is swampy and covered mixed forest. The share of snow supply makes up more than half of the runoff for the year, and the maximum flood in Chumysh is in April.

Lakes of Altai

Picturesque Altai lakes. There are thousands of them in the region, and they are located throughout the territory.

Most of the lakes are located in the Kulunda Lowland and on the Priob Plateau. It’s not for nothing that Altai is called the land of blue lakes. Small mountain and steppe lakes give natural landscapes a unique charm and uniqueness.

The largest lake in the Altai region is a bitter-salty lake Kulundinskoe(area 600 sq. km, length - 35 and width 25 km). It is shallow, ( maximum depth- 4 m), fed by the waters of the Kulunda River and groundwater. South of Kulundinsky there is the second largest lake - Kuchukskoe(area 180 sq. km). It is completely similar in regime and nutrition to Kulundinsky and was previously connected to it by a channel.

Kulunda the lakes are all remnants of an ancient sea that existed many millions of years ago on the site of the present plains. Many of these lakes have long been famous for their mineral waters, having healing properties, as well as healing clays and mud. Gorkoe-Isthmus, Raspberry- are places of pilgrimage for residents of the region and numerous guests. On the salty Bolshoi Yarov the lake has been healing for many years health complex. Salty water, abundance of steppe sun, picturesque Pinery The shores of such lakes create unique conditions for recreation.

There is a lot of fish in the fresh flowing lakes, and waterfowl in the reed thickets along the banks.

The lakes of the mountainous part of the Altai Territory are very picturesque. They are located in the hollows of ancient drainage, on the site of old riverbeds that have long disappeared mountain rivers, which arose during the melting of an ancient glacier.

Between the Biya and Chumysh rivers there are small and shallow freshwater lakes. There are lakes on the floodplains of lowland rivers, and in ancient and modern river valleys there are small elongated lakes - oxbow lakes.

The Altai region is also rich in mineral springs. What makes it especially famous is its radon springs, which have been used by the local population for medicinal purposes since time immemorial. Both in our country and abroad, the famous radon waters of Belokurikha are famous, where numerous resorts and health resorts have been built. The presence of radon waters was noted in the valleys of the Kalmanka and Berezovaya rivers.

Waterfalls are also common in Altai, like a waterfall on a river Shinok, not far from Denisova Cave, about 70 meters high, until recently it was known only local residents. Now many people dream of visiting here. Currently, there are eight waterfalls and one waterfall on the Shinok River. In 2000, the Cascade of Waterfalls on the Shinok River reserve acquired the status of a natural monument.

The lakes of the mountainous part of the Altai Territory are very picturesque. They are located in the hollows of ancient drainage, on the site of old channels of long-vanished mountain rivers that arose when an ancient glacier melted.

Lake Aya

The unique beauty of Lake Kolyvan, along the shores of which quaint castles of granite rocks are piled up. You can admire the stone sculptures of fantastic animals while lying on the sandy beach.

Kolyvan Lake

Many of these lakes form long chain, connecting with each other through channels and small rivers. Some of these lakes give rise to the left tributaries of the Ob (the Barnaulka River, flowing through the territory of the regional center, originates from such lakes located in the forest near the villages of Peschanoye and Voronikha).

Waterfalls are also common in Altai, like the waterfall on the Shinok River, not far from Denisova Cave, about 70 meters high, which until recently was known only to local residents.

The Barnaulka River is a tributary of the Ob River

The name of the great river "Ob" It owes its origin not to the peoples who have lived on its shores from time immemorial. The Nenets living in the lower reaches of the river called it “Sala-yam”, which means “Cape River”. The Khanty and Mansi gave it the name “As” - “big river”, the Selkups called the river “Kvay”, “Eme”, “Kuay”. All these names meant “large river.” The Russians first saw the river in its lower reaches when hunters and merchants, together with Zyryan guides, went beyond the Stone (as the Ural Mountains were then called). Long before Ermak’s conquest of Siberia, the region around the Ob was called Obdorsky.

There is a version that the name of the great Siberian river comes from the Komi language, which meant “snow”, “snowdrift”, “place near the snow”.

River Ob

But there is also an ingenuous version that the word “Ob” comes from the Russian “both”, that is, “both rivers” - “Ob”, meaning two rivers - Katun and Biya, which merged into the mighty beauty Ob.

Biya
Biya is the second largest river in Altai. It originates in Lake Teletskoye. Its length is 280 kilometers. It is considered navigable along its entire length in big water. In the upper part of the river there are rapids, waterfalls, and rifts. Merging with Katun, Biya gives rise to the Ob.

Biya River

Name of Biya associated with the Altai words “biy”, “beg”, “bii” - “lord”. According to one of the Altai legends, the words “master” and “mistress” sound like the names of Biya and Katun. In his works, N.M. Yadrintsev wrote that the direction of the flow of these rivers is explained by the fact that a man and a woman wanted to compete to see who would run across whom. Katun tried to run across Biya, and then the offended man Biya crossed her path. According to other sources, the name Biya comes from the ancient Turkic “bey” - “river”, or the Samoyedic “ba” - “river”.

Katun
The Katun flows from the Gebler glacier at an altitude of about 2000 meters on the southern slope of the highest mountain in Altai - Belukha. In the upper and middle reaches, the river has a mountainous character, especially in the summer, when snow and glaciers melt intensively. In the lower reaches it acquires a flat character, spreading below the village. The Maima has channels and channels, and flows along an inclined plain to the north until it merges with the Biya.

The water in the Katun is cold, its temperature in summer rarely rises above 15 C. The river is fed mainly by the melting of snow and ice from glaciers. The length of the river is 665 kilometers; in its basin there are about 7,000 waterfalls and rapids.

Katun River

About the origin of the name "Katun" consensus does not exist. According to one version, the term “katun” is based on the ancient Turkic “kadyn” or “khatun” - “mistress”, “mistress”. This is due to the ancient custom of worshiping large rivers, exalting them in their names. In other languages there are such additions, for example, “oros-khatun” in Yakut - “mother river”. During the time of Genghis Khan, the Mongols used the word "khatun" to mean "river". “Boga-khatun” - “small river”, “ihi-khatun” - “big river”. There is a version that the word “katun” comes from “katanga” - “water”, “river”, as rivers from Western Siberia were called to the Pacific Ocean.

Aley
Alei is the largest tributary of the Ob on the flat part of the region. In length (755 km) it exceeds Katun and Biya, but is inferior to them in terms of water content. Alei originates in the low mountains of northwestern Altai. This is a river with a mixed type of feeding (snow and rain), the spring flood reaches its maximum in April.

IN fresh flowing lakes there is a lot of fish, and in the thickets of reeds along the banks - waterfowl. The lakes of the mountainous part of the Altai Territory are very picturesque. They are located in the hollows of ancient drainage, on the site of old channels of long-vanished mountain rivers that arose when an ancient glacier melted.
