See also:VOLGA (known to the See also:Tatars as Etil, Jill or Atel; to the Finnish tribes as See also:Rau, and to the ancients as Rha and Oarus)
, the longest and most important See also:river of See also:European See also:Russia
.
It rises in the Valdai See also:plateau of See also:Tver and, after a winding course of 232; M

(1070 in a straight See also:line), falls into the See also:Caspian at See also:Astrakhan
.
It is by far the longest river of See also:Europe, the

5Danube, which comes next to it, being only 1775 m., while the See also:Rhine (76o m.) is shorter even than two of the See also:chief tributaries of the See also:Volga—the Oka and the See also:Kama
.
Its drainage See also:area, which includes the whole of See also:middle and eastern as well as See also:part of See also:south-eastern Russia, amounts to 563,300 sq. m., thus exceeding the aggregate superficies of See also:Germany, See also:France and the See also:United See also:Kingdom, and containing a See also:population of fifty millions
.
Its tributaries are navigable for an aggregate length of nearly 20,000 m
.
The " See also:basin " of the Volga is not limited to its actual catchment area
.
By a See also:system of canals which connect the upper Volga with the See also:Neva, the commercial mouth of the Volga has been transferred, so to speak, from the Caspian to the Baltic, thus making St See also:Petersburg, the See also:capital and chief seaport of Russia, the chief See also:port of the Volga basin as well
.
Other less important canals connect it with the Western See also:Dvina (See also:Riga) and the See also: See also:Lake Seliger was formerly considered to be the See also:principal source;but that distinction is now given to The upper a small See also:spring issuing beneath a See also:chapel (57 15' N.; 32° 3o river . E.) in the midst of a large See also:marsh to the See also:west of Seliger . The See also:honour has also been claimed, not without plausibility, for the Runa rivulet . See also:Recent exact surveys have shown these originating marshes to be no more than 665 ft. above sea-level . The stream first traverses several small lakes, all having the same level, and, after its confluence with the Runa, enters Lake Volga . A See also:dam erected a few See also:miles below that lake, with a storage of nearly 1o,000 million cub. ft. of See also:water, makes it possible to raise the level of the Volga as far down as the Sheksna, thus rendering it navigable, even at See also:low water, from its 65th mile onwards . From its confluence with the Sheksna the Volga flows with a very See also:gentle descent towards the south-See also:east, past See also:Yaroslavl and See also:Kostroma, along a broad valley hollowed to a See also:depth of 150-200 ft. in the See also:Permian and See also:Jurassic deposits . In fact, its course lies through a See also:string of depressions formerly filled with wide lakes, all linked together . When the Volga at length assumes a due south-east direction it is a large river (825o cub. ft. per second, rising occasionally in high See also:flood to as much as 178,360 cub. ft.) ; of its numerous tributaries, the Unzha (365 m., 330 navigable), from the See also:north, is the most important . The next great tributary is the Oka, which comes from the south-west after having traversed, on its course of 950 m., all the Great See also:Russian provinces of central Russia . It rises in the govern- confiament of See also:Orel, among hills which also send tributaries to the ence with See also:Dnieper and the Don, and receives on the See also:left the Upa, the the Oka . Zhizdra, the Ugra (300 m.), the Moskva, on which steamers ply up to See also:Moscow, the Klyazma (395 m.), on whose See also:banks arose the middle-Russian principality of Suzdal, and on the right the navigable Tsna (255 m.) and Moksha . Every one of these tributaries is connected with some important event in the See also:history of Great Russia . The drainage area of the Oka is a territory of 97,000 sq. m . It has been maintained that, of the two See also:rivers which unite at Nizhniy-See also:Novgorod, the Oka, not the Volga, is the chief ; the fact is that both in length (818 m.) and in drainage area above the confluence (89,500 sq. m.), as well as in the aggregate length of its tributaries, the Volga is the inferior stream . At its confluence with the Oka the Volga enters the broad lacustrine depression which must have communicated with the Caspian during the See also:post-See also:Pliocene See also:period by means of at least a broad strait . Lams . Its level at low water is only 190 ft. above that of the ocean. trine de . Immediately below the confluence the breadth of the river pressions. ranges from 350 to 1750 yds . There are many islands which See also:change their See also:appearance and position after each inundation . On the right the Volga is joined by the Sura, which drains a large area and brings a See also:volume of 2700 to 22,000 cub. ft. of water per second, the Vetluga (465 M. See also:long, of which 365 are navigable), from the See also:forest-tracts of Yaroslavl, and many smaller tributaries . Then the stream turns south-east and descends into another lacustrine depression, where it receives the Kama, below Kazan . Remains of molluscs still extant in the Caspian occur extensively throughout this depression and up the lower Kama . The Kama,' which brings to the Volga a contribution ranging from 52,500 to 144,400 cub. ft. and occasionally reaching 515,000 cub. ft. per second, might again be considered as the more important of the two rivers . It rises in See also:Vyatka, takes a wide sweep towards the north and east, and then flows south and south-west to join the Volga after a course of no less than I150 m . i To the Votyaks it is known as the Budzhim-Kam, to the Chuvashcs as the Shoiga-adil and to the See also:Tatars as the Cholman-idel or Ak-idel, all words signifying " White river." 11 M3 Along the next 738 m. of its course the Volga—now 580 to 2600 yds. wide—flows south-south-west, with but one great See also:bend at See also:Samara . At this point, where it pierces a range of See also:limestone hills, the course of the river is very picturesque, fringed as it is by cliffs which rise moo ft. above the level of the stream (which is only 54 ft. above the sea at Samara) . Along the whole of the Samara bend the Volga is accompanied on its right hank by high cliffs, which it is constantly undermining, while broad See also:lowland areas stretch along the left or eastern See also:bank, and are intersected by several old beds of the Volga . At See also:Tsaritsyn the great river reaches its extreme south-western limit, and is there separated from the Don by an See also:isthmus only 45 m. in width . The isthmus is too high to be crossed by means of a See also:canal, but a railway to See also:Kalach brings the Volga into some sort of connexion with the Don and the Sea of Azov . At Tsaritsyn the river takes a See also:sharp turn in a south-easterly direction towards the Caspian; it enters the Caspian See also:steppes, and a few miles above Tsaritsyn sends off a See also:branch—the Akhtuba—which accompanies it for 330 m. before falling into the Caspian . Here the Volga The lower receives no tributaries; its right bank is skirted by low rlvErand hills, but on the left it anastomoses freely with the See also:delta . Akhtuba when its See also:waters are high, and floods the See also:country for 15 to 35 M . The width of the See also:main stream ranges from 520 to 3500 yds. and the depth exceeds 8o ft . The delta proper begins 40 m. above Astrakhan, and the branches subdivide so as to reach the sea by as many as 200 See also:separate mouths . Below Astrakhan See also:navigation is difficult, and on the See also:sand-bars at the mouth the maximum depth is only 12 ft. in cahn See also:weather . The figures given show how immensely the river varies in volume, and the greatness of the changes which are constantly going on in the channel and on its banks . Not only does its level occasionally rise in flood as much as 50 ft. and overflow its banks for a distance of 5 to 15 m.; even the level of the Caspian is considerably affected by the sudden influx of water brought by the Volga . The amount of suspended See also:matter brought down is correspondingly great . All along its course the Volga is eroding and destroying its banks with great rapidity; towns and loading ports have constantly to be shifted farther back . The question of the See also:gradual See also:desiccation of the Volga, and its causes, has often been discussed, and in 1838 a See also:committee which included Karl See also:Baer among its members was appointed by the Russian See also:academy of sciences to investigate the subject . No See also:positive result was, however, arrived at, principally on See also:account of the want of See also:regular measurements of the volume of the Volga and its tributaries—measurements which began to be made on scientific principles only in 1880 . Still, if we go back two or three centuries, it is indisputable that rivers of the Volga basin which were easily navigable then are now hardly accessible to the smallest See also:craft . The desiccation of the rivers of Russia has been often attributed to the steady destruction of its forests . But it is obvious that there are other See also:general causes at See also:work, which are of a much more important See also:character—causes of which the larger phenomena of the general desiccation of Eastern and Western See also:Turkestan are contemporaneous manifestations . The gradual See also:elevation of the whole of See also:northern Russia and See also:Siberia, and the consequent draining of the marshes, is one of these deeper-seated, ampler causes; another is the desiccation of the lakes all over the northern hemisphere . See also:Fisheries.—The network of shallow and still limans or " cut-offs " in the delta cf the Volga and the shallow waters of the northern Caspian, freshened as these are by the water of the Volga, the Ural, the Kura and the See also:Terek, is exceedingly favourable to the breeding of See also:fish, and as a whole constitutes one of the most productive fishing grounds in the See also:world . As soon as the See also:ice breaks up in the delta innumerable shoals of See also:roach (Leuciscus rulilus) and See also:trout (Luciotrutta leucichthys) See also:rush up the river, They are followed by the great See also:sturgeon (Acipenser huso), the See also:pike, the See also:bream and the pike See also:perch (Leucioperca sandra) .
Later on appears the Caspian See also:herring (Clupea See also:case a), which formerly was neglected, but has now become more important than sturgeon; the sturgeon A. stellatus and " See also:wels " (See also:Silures glanis) follow, and finally the sturgeon Acipenser guldenstadtii, so much valued for its See also:caviare
.
In See also:search of a gravelly spawning-ground the sturgeon go up the river as far as Sarepta (250 m.)
.
The See also:lamprey, now extensively pickled, the sterlet (A. rut/terms), the See also:tench, the See also:gudgeon and other fluvial See also:species also appear in immense See also:numbers
.
It is estimated that 18o,000 tons of fish of all kinds, of the value of considerably over L1,5o0,000, are taken annually in the four fishing districts of the Volga, Ural, Terek and Kura
.
See also:Seal-See also:hunting is carried on off the
Volga mouth, and every See also:year about 40,000 of Phoca vitulina are killed to the north of the 1Vlanghishlak See also:peninsula on the east See also:side of the Caspian
.
Ice Covering.—In See also:winter the numberless tributaries and sub-tributaries of the Volga become highways for sledges
.
The ice lasts 90 to 16o days, and breaks up earlier in its upper course than in some parts lower down
.
The See also:average date of the break-up is See also:April iith at Tver, and 14 days later about Kostroma, from which point a regular See also:acceleration is observed (April 16th at Kazan, April 7th at Tsaritsyn, and See also: The following table shows the principal river ports, with the See also:movement of See also:shipping in an average year: Chief River Vessels .

See also:Horse-See also:power is still extensively resorted to along the three canal systems . The first large steamers of the See also:American type were built in 1872 . Thousands of steamers are now employed in the traffic, to say nothing of smaller boats and rafts . Many of the steamers use as See also:fuel mazut or petroleum refuse . Large numbers of the boats and rafts are broken up after a single voyage . History.—The Volga was not improbably known to the See also:early Greeks, though it is not mentioned by any writer previous to See also:Ptolemy . According to him, the Rha is a tributary of an interior sea, formed from the confluence of two great rivers, the See also:sources of which are separated by twenty degrees of See also:longitude, but it is scarcely possible to See also:judge from his statements how far the Slays had by that, See also:time succeeded in penetrating into the basin of the Volga . The Arab geographers throw little See also:light on the See also:condition of the Volga during the great migrations of the 3rd See also:century, or subsequently under the invasion of the See also:Huns, the growth of the Khazar See also:empire in the See also:southern steppes and of that of See also:Bulgaria on the middle Volga . But we know that in the 9th century the Volga basin was occupied by Finnish tribes in the north and by See also:Khazars and various See also:Turkish races in the south . The Slays, driven perhaps to the west, had only the Volkhov and the Dnieper, while the (See also:Mahommedan) Bulgarian empire, at the confluence of the Volga with the Kama, was so powerful that for some time it was an open question whether See also:Islam or See also:Christianity would gain the upper See also:hand among the Slav idolaters . But, while the Russians were driven from the See also:Black Sea by the Khazars, and later on by a See also:tide of Ugrian See also:migration from the north-east, a stream of Slays moved slowly towards the north-east, down the upper Oka, into the borderland between the Finnish and Turkish regions . After two centuries of struggle the Russians succeeded in colonizing the fertile valleys of the Oka basin; in the 12th century they built a See also:series of fortified towns on the Oka and Klyazma; and finally they reached the mouth of the Oka, there See also:founding (in 1222) a new Novgorod—the Novgorod of the Lowlands, now Nizhniy-Novgorod . The great lacustrine depression of the middle Volga was thus reached; and when the Mongol invasion of 1239-42 came, it encountered in the Oka basin a dense agricultural population with many fortified and wealthy towns—a population which the See also:Mongols found they could conquer, indeed, but were unable to drive before them as they had done so many of the Turkish tribes . The Samara bend . This invasion checked but did not stop the advance of the Russians down the Volga . Two centuries elapsed before the Russians covered the 300 M. which separate the mouths of the Oka and the Kama and took See also:possession of Kazan . But in the meantime a flow of Novgorodian colonization had moved eastward, along the upper portions of the left-bank tributaries of the Volga, and had reached the Urals . With the See also:capture of Kazan (1552) the Russians found the lower Volga open to their boats, and eight years afterwards they were masters of the mouth of the river at Astrakhan . Two centuries more elapsed before the Russians secured a See also:free passage to the Black Sea and became masters of the Sea of Azov and the See also:Crimea; the Volga, however, was their route . During these two centuries they fortified the lower river, settled it, and penetrated farther eastward into the steppes towards the upper Ural and thence to the upper parts of the Tobol and other great Siberian rivers . |
