Along the portion of the south shore of the Gulf of Carpentaria which belongs to Queensland and the east coast, many large rivers discharge their waters, amongst them the Norman, Flinders, Leichhardt, Albert and Gregory on the southern shore, and the Batavia, Archer, Coleman, Mitchell, Staaten and Gilbert on the eastern shore.
The rivers flowing into the Gulf of Carpentaria, as well as those in the Northern Territory, drain country which is subject to regular monsoonal rains, and have the general characteristics of sub-tropical rivers.
The so-called rivers have a strong flow only after heavy rains, and some of them do not ever reach the main drainage line.
In many cases the rivers as they approach the main stream break up into numerous branches, or spread their waters over vast flats.
This is especially the case with the tributaries of the Darling on its left bank, where in seasons of great rains these rivers overspread their banks and flood the flat country for miles around and thus reach the main stream.
The great rivers of Australia, draining inland, carve out valleys, dissolve limestone, and spread out their deposit over the plains when the waters become too sluggish to bear their burden farther.
All Australian rivers, except the Murray and the Murrumbidgee, depend entirely and directly on the rainfall.
Springs which would equalize the discharge of rivers by continuing to pour water into their beds after the rainy season has passed seem entirely absent in the interior.
Nor are there any snowfields to feed rivers, as in the other continents.
As the general level of the country is raised by successive alluvial deposits, the more ancient river-beds become buried, but being still connected with the newer rivers at some point or other, they continue to absorb water.
It is this tropical downpour that fills and floods the rivers flowing into Lake Eyre and those falling into the Darling on its right bank.
The sea produces three different seals, which often ascend rivers from the coast, and can live in lagoons of fresh water; many cetaceans, besides the " right whale " and sperm whale; and the dugong, found on the northern shores, which yields a valuable medicinal oil.
So far the mud-fish has been found only in the Mary and the Burnett rivers.
Excellent fish of many varieties abound in the Australian seas and in many of the rivers.
The principal deposits of copper in New South Wales are found in the central part of the state between the Macquarie, Darling and Bogan rivers.
The most important tin-mines in Queensland are in the Herberton district, south-west of Cairns; at Cooktown, on the Annan and Bloomfield rivers; and at Stanthorpe, on the border of New South Wales.
Their nets, made by women, either of the tendons of animals or the fibres of plants, will catch and hold the kangaroo or the emu, or the very large fish of Australian rivers.
Oxley now turned aside - led by Mr Evans's report of the country eastward - crossed the Arbuthnot range, and traversing the Liverpool Plains, and ascending the Peel and Cockburn rivers to the Blue Mountains, gained sight of the open sea, which he reached at Port Macquarie.
By this time much had thus been done to obtain an acquaintance with the eastern parts of the Australian continent, although the problem of what could become of the large rivers flowing north-west and south-west into the interior was still unsolved.
The Barcoo or Cooper's Creek and its tributary streams were traced from the Queensland mountains, holding a south-westerly course to Lake Eyre in South Australia; the Flinders, the Gilbert, the Gregory, and other northern rivers watering the country towards the Gulf of Carpentaria were also explored.
Hann, with Messrs Warner, Tate and Taylor, in 1873, related to the country north of the Kirchner range, watered by the Lynd, the Mitchell, the Walsh and the Palmer rivers, on the east side of the Gulf of Carpentaria.
Elphinstone Dalrymple, with Messrs Hill and Johnstone, finishing in December 1873, effected a valuable survey of the inlets and navigable rivers in the Cape York Peninsula.
John (afterwards Sir John) Forrest was despatched by the Perth government with general instructions to obtain information regarding the immense tract of country out of which flow the rivers falling into the sea on the northern and western shores of Western Australia.
The chief streams are the Werra, which traverses the south and east of the duchy, and various tributaries of the Main and the Saale, so that Saxe-Meiningen belongs to the basins of the three great rivers Weser, Rhine and Elbe.
The neighbouring valleys of the Gandara and Hippatan rivers are exceedingly fertile, but in 1908 were uncultivated.
Only an insignificant fraction of these forests has ever been visited by human beings, the Malays and even the aboriginal tribe having their homes on the banks of the rivers, and never, even when travelling from one part of the country to another, leaving the banks of a stream except for a short time when passing from one river-system to another.
The principal rivers on the west coast are the Perak, the Bernam and the Muar.
The deepest rivers are the Kuantan and Rompin; the largest are the Kelantan and the Pahang, both of which are navigable for native boats for a distance of over 250 m.
The rivers on the east coast are practically the only highways, the Malays always travelling by boat in preference to walking, but they serve their purpose very indifferently, and their great beauty is their chief claim to distinction.
The Deerfield, West, Williams, White, Passumpsic and Nulhegan rivers are the largest of the many streams which are tributary to the Connecticut.
The Black, Barton and Clyde rivers flow into Lake Memphremagog.
Vermont's rivers are generally swift, and in many places they are made very picturesque by their clear and sparkling waters, rapids, falls, gorges and wooded banks.
The first important industry of the state was "rafting" lumber from Vermont through Lake Champlain and the Richelieu and St Lawrence rivers to Quebec. Burlington became a great lumber market for a trade moving in the direction of Boston after the Richelieu river was blocked to navigation and railway transportation began, and in 1882 Burlington was the third lumber centre in the United States.
The rivers of the province belong to the basins of the Indian Ocean and the Java Sea respectively, the water-parting being formed by the western and eastern ends respectively of the northern and southern lines of mountain peaks.
The Chi Tandui, also rising here, flows south-east to the Indian Ocean, and alone of all the rivers in this province is navigable.
The position is strong, being protected by the two rivers mentioned, and the medieval fortifications, which are nearly 2 m.
The terrigenous deposits consist of blue muds, red muds (abundant along the coast of Brazil, where the amount of organic matter present is insufficient to reduce the iron in the matter brought down by the great rivers to produce blue muds), green muds and sands, and volcanic and coral detritus.
The Sio and Haho, the two largest rivers of the coast region, both flow into the Togo lagoon.
These rivers rise on the eastern versant of a chain of mountains which traverse the country in a south-westerly to north-easterly direction.
The chief rivers of Rajputana are the Luni, the Chambal and the Banas.
A few miles below Valenza it is joined by the Tanaro, a large stream, which brings with it the united waters of the Stura, the Bormida and several minor rivers.
More important are the rivers that descend from the main chain of the Graian and Pennine Alps and join the Po on its left bank.
The Adige, formed by the junction of two streams—the Etsch or Adige proper and the Eisak, both of which belong to Tirol rather than to Italy—descends as far as Verona, where it enters the great plain, with a course from north to south nearly parallel to the rivers last described, and would seem likely to discharge its waters into those of the Po, but below Legnago it turns eastward and runs parallel to the Po for about 40 m., entering the Adriatic by an independent mouth about 8 m.
The waters of the two rivers have, however, been made to communicate by artificial cuts and canals in more than one place.
It is occupied by the branches and offshoots of the mountain ranges which separate it from the great plain to the north, and send down their lateral ridges close to the water's edge, leaving only in places a few square miles of level plains at the mouths of the rivers and openings of the valleys.
From the proximity of the mountains to the sea none of the rivers in this part of Italy has a long course, and they are generally mere mountain torrents, rapid and swollen in winter and spring, and almost dry in summer.
The most considerable rivers of Tuscany south of the Arno are the Cecina, which flows through the plain below Volterra, and the Ombrone, which rises in the hills near Siena, and enters the sea about 12 m.
The central range here approaches much nearer to the sea, and hence, with few exceptions, the rivers that flow from it have short courses and are of comparatively little importance.
The whole of the district known in ancient times as Samnium (a part of which retains the name of Sannio, though officially designated the province of Campobasso) is occupied by an irregular mass of mountains, of much inferior height to those of Central Italy, and broken up into a number of groups, intersected by rivers, which have for the most part a very tortuous course.
None of the rivers of Southern Italy is of any great importance.
Below this the watershed of the Apennines is too near to the sea on that side to allow the formation of any large streams. Hence the rivers that flow in the opposite direction into the Adriatic and the Gulf of Taranto have much longer courses, though all partake of the character of mountain torrents, rushing down with great violence in winter and after storms, but dwindling in the summer into scanty streams, which hold a winding and sluggish course through the great plains of Apulia.
Proceeding south from the Trigno, already mentioned as constituting the limit of Central Italy, there are (1) the Biferno and (2) the Fortore, both rising in the mountains of Samnium, and flowing into the Adriatic west of Monte Gargano; (3) the Cervaro, south of the great promontory; and (4) the Ofanto, the Aufidus of Horace, whose description of it is characteristic of almost all the rivers of Southern Italy, of which it may be taken as the typical representative.
They have been already noticed in connection with the rivers by which they are formed, but may be again enumerated in order of succession.
It is a great depression—the continuation of the Adriatic Sea—filled up by deposits brought down by the rivers from the mountains.
The total length of navigable rivers is 967 m.
The great extension of Italian coast-line is thought by some to be not really a source of strength to the Italian mercantile marine, as few of the ports have a large enough hinterland to provide them with traffic, and in this hinterland (except in the basin of the Po) there are no canals or navigable rivers.
They fought for bare existence, for primacy in commerce, for the command of seaports, for the keys of mountain passes, for rivers, roads and all the avenues of wealth and plenty.
This was intended to give greater freedom to inland navigation, the rivers being the main highways of trade.

Beyond the limits of his personal travels Herodotus applied the characteristically Greek theory of symmetry to complete, in the unknown, outlines The ides of lands and rivers analogous to those which had been of symexplored.
He formed a comprehensive theory of the variations of climate with latitude and season, and was convinced of the necessity of a circulation of water between the sea and rivers, though, like Plato, he held that this took place by water rising from the sea through crevices in the rocks, losing it .s dissolved salts in the process.
Excellent examples of the indecisive drainage of a new land surface, on which the river system has not had time to impress itself, are to be seen in northern Canada and in Finland, where rivers are separated by scarcely perceptible divides, and the numerous lakes frequently belong to more than one river system.
By a re-elevation of a peneplain the rivers of an old land surface may be restored to youthful activity, and resume their shaping action, deepening the old valleys and initiating new ones, starting afresh the whole course of the geographical cycle.
The whole question of the regime of rivers and lakes is sometimes treated under the name hydrography, a name used by some writers in the sense of marine surveying, and by others as synonymous with oceanography.

For practical studies see official reports on the Mississippi, Rhine, Seine, Elbe and other great rivers.
On the fertile low grounds along the margins of rivers or in clearings of forests, agricultural communities naturally take their rise, dwelling in villages and cultivating the wild grains, which by careful nurture and selection have been turned into rich cereals.
Rivers do not form effective international boundaries, although between dependent self-governing communities they are convenient lines of demarcation.
There are many pleasant drives along the shore of the bay or the banks of rivers, and some of these lead to popular resorts, such as Riverton Park, on the Presumpscot; Cape Cottage Park, at the mouth of the harbour; and Falmouth Foreside, bordering the inner bay.
The chief rivers of the eastern region are the Valserine and the Seran, right-hand tributaries of the Rhone, which forms the eastern and southern boundary of the department; and the Albarine and Oignin, left-hand affluents of the Ain.

It is an inhabitant of the rivers and streams of Europe north of the Alps, but it is most abundant in those of France and Germany.
In the time of the Arabs these were the chief canals, and the cuts from the main channels of the Nahr `Isa, Nahr Sarsar, Nahr Malk (or Nahr Malcha), and Nahr Kutha, reticulating the entire country between the rivers, converted it into a continuous and luxuriant garden.
The fact also that many of the most ancient of these ruins, like Ur, Lagash (Sirpurla), Larsa, Erech, Nippur, Sippara and Babylon, were situated on the banks of the great canals would indicate that the control of the waters of the rivers by a system of canalization and irrigation was one of the first achievements of civilization.
By far the greater part of the country was a plain watered by numerous rivers, the chief of which have already been mentioned, with the exception of its great central stream, the Liger or Ligeris (Loire).
The boundaries separating it from Rio Grande do Sul, a province of Brazil, are Lake Mirim, the rivers Chuy, Jaguarao and Quarahy, and a cuchilla or low range of hills called Santa Ana.
Besides the rivers mentioned, the chief streams are the Santa Lucia, which falls into the Plata a little west of Montevideo; the Queguay, in Paysandu; and the Cebollati, rising in the sierras in Minas and flowing into Lake Mirim.

The fish of the lagoons and streams are coarse, and some of them primitive in type; but two or three kinds, found generally in the large rivers, are much prized.
In addition to the natural lines of communication provided by the rivers bordering on or belonging to the republic, there are about 2240 m.
In the deltas of shoal rivers, with a strong tide or current and no land visible, a 5 lb lead is substituted for the log-ship; the lead rests on the bottom, and the speed is obtained in a manner similar to that previously described.
The general slope of the plateau is toward the N., and the drainage of the state is chiefly through the above-named rivers - the principal tributaries of the Araguaya being the Grande and Vermelho, and of the Upper Tocantins, the Manoel Alves Grande, Somno, Paranan and Maranhao.
Several rivers, of which the Komo is the chief, discharge their waters into the estuary.
As most of the rivers have rapids or falls actually at the sea coast or close to it, they are, with the exception of the Cavalla, useless for penetrating far inland, and the whole of this part of Africa from Cape Palmas north-west to the Senegal suggests a sunken land.
Although very little of the coast belt is actually swampy, a kind of natural canalization connects many of the rivers at their mouths with each other, though some of these connecting creeks are as yet unmarked on maps.
The Dukwia and Farmington are tortuous rivers entering the sea under the name of the river Junk (Portuguese, Junco).
It extends between the Duobe and the Cavalla rivers.
In the rivers and swamps there are soft-shelled turtle (Trionyx and Sternothaerus).

The rivers are not navigable.
Russia; the Valdai tablelands, where all the great rivers of Russia take their rise; the broad and gently sloping meridional belt of the Ural Mountains; and lastly the Taimyr, Tunguzka and Verkhoyansk ranges in Siberia, which, notwithstanding their sub-Arctic position, do not reach the snow-line.
It is owing to these leading orographical features - divined by Carl Ritter, but only recently ascertained and established as fact by geographical research - that so many of the great Rivers.
The deposits of the Post-Glacial period are represented throughout Russia, Poland and Finland, as also throughout Siberia and Central Asia, by very thick lacustrine deposits, which show that, after the melting of the ice-sheet, the country was covered with immense lakes, connected by broad channels (the fjarden of the Swedes), which later on gave rise to the actual rivers.
This upheaval - the consequences of which have been felt even within the historic period, by the drainage of the formerly impracticable marshes of Novgorod and at the head of the Gulf of Finland - together with the destruction of forests, contributes towards a decrease of precipitation over Russia and towards increased shallowness of her rivers.
At the same time, as the gradients are gradually increasing on account of the upheaval of the continent, the rivers dig their channels deeper and deeper.
The round flattened summits of the Valdai plateau do not rise above 1100 ft., and they present the appearance of mountains only in consequence of the depths of the valleys - the rivers which flow towards the depression of Lake Peipus being only 200 to 250 ft.
Taking their origin from a series of lacustrine basins scattered over the plateaus and differing slightly in elevation, the Russian rivers describe immense curves before reaching the sea, and flow with a very gentle gradient, while numerous large tributaries collect their waters from over vast areas.
Dvina, and the Pripet, both very important for navigation - as well as several smaller tributaries on which rafts are floated; on the left the Sozh, the Desna, one of the most important rivers of Russia, navigated by steamers as far as Bryansk, the Sula, the Psiol and the Vorskla.
A great variety of monographs dealing with separate rivers and basins are available; e.g.
The rapid melting of the snow at the same time causes the rivers to swell, and renders a.
The rivers freeze rapidly; towards November 10th all the streams of the White Sea basin are ice-bound, and so remain for an average of 167 days; those of the Baltic, Black Sea and Caspian basins freeze later, but about December the 10th nearly all the rivers of the country are highways for sledges.
Not a tree is to be seen, the few woods and thickets being hidden in the depressions and deep valleys of the rivers.
The vegetation in the marshy bottoms of the ravines and in the valleys of the streams and rivers is totally different.
Europe, except the carp, are met with in the lakes and rivers in immense quantities, the characteristic feature of the region being its wealth in Coregoni and in Salmonidae generally.
The absence of Coregoni is a characteristic feature of the fish-fauna of the steppes; the carp, on the contrary, reappears, and the rivers abound in sturgeon (Acipenseridae).
The mouths of the Caspian rivers are especially celebrated for their wealth of fish.2 Ethnography.
All over Russia there is a network of such artels - in the cities, in the forests, on the banks of the rivers, on journeys and even in the prisons.

Larger rivers, canals, roads, other railways and sometimes deep narrow valleys are crossed by bridges (q.v.) of timber, brick, stone, wrought iron or steel, and many of these structures rank among the largest engineering works in the world.
The three principal areas in which irrigation is practicable are along the Humboldt river, in the plains watered by the Carson, Truckee and Walker rivers, and at the foot of the mountains along the western edge of the state.
The oldest of these trunk lines, the Southern Pacific (formerly the Central Pacific), follows the course of the Humboldt and Truckee rivers.

The southern half of the state, however, slopes eastward and is drained directly into the Atlantic through a number of small rivers, the largest of which are the Irapiranga (whose source is in the state of Bahia and which is called Vasa Barris at its mouth), the Real, and the Cotinguiba.
There are no good ports on the coast because of the bars at the mouths of the rivers.
Put comprehensively, it involves the control of the subsoil and surface waters by drainage, the regulation of rivers and floods, suitable agriculture, the clearing of forests or jungles, which tend to increase the rainfall and keep the ground swampy.
Even at that period, however, the silt brought down by the rivers rendered access to the harbour difficult, and the historian Philistus excavated a canal to give free access to the sea.
The most remarkable of these rivers is the Laibach, which rises in the Karst region under the name of Poik, takes afterwards a subterranean course and traverses the Adelsberg grotto, and appears again on the surface near Planina under the name of Unz.
Augustus joined it with Lucania (from which it was divided by the rivers Laus and Crathis) to form the third region of Italy.
The Lerma, on the northern frontier, and the Balsas on the southern, are the only rivers of importance of the state, their tributaries within its boundaries being small and swift-flowing.

Buffalo-fish, paddle-fish, cat-fish, drum, crappie, black bass, rock bass, German carp, sturgeon, pike, perch, eels, suckers and shrimp inhabit the waters of the Mississippi and its tributaries, and oysters, shrimp, trout, Spanish mackerel, channel bass, black bass, sheepshead, mullet, croakers, pompano, pin-fish, blue-fish, flounders, crabs and terrapin are obtained from the Mississippi Sound and the rivers flowing into it.
Pine stumps and waste limbs are utilized, notably at Hattiesburg, for the manufacture of charcoal, tar, creosote, turpentine, &c. Fisheries Fishing is a minor industry, confined for the most part to the Mississippi Sound and neighbouring waters and to the Mississippi and Yazoo rivers.
The Yazoo, Tallahatchie, Yalobusha, Sunflower, Big Black, Pascagoula and Pearl rivers are also navigable to a limited extent.
Projecting into these sounds and between the estuaries of rivers flowing into them are extensive tracts of swamp land - the best known of these is Dismal Swamp, which lies mostly in Virginia and is about 3 o m.
In the Mountain Region and in the Piedmont Plateau Region the rivers have numerous falls and rapids which afford a total water power unequalled perhaps in any other state than Maine on the Atlantic Coast, the largest being on the Yadkin, Roanoke and Catawba; and in crossing some of the mountains, especially the Unakas, the streams have carved deep narrow gorges that are much admired for their scenery.
In contrast with the rivers of these regions those of the Coastal Plain are sluggish, and toward their mouths expand into wide estuaries.
Large numbers of shad, blue fish, weak fish (squeteague), alewives, Spanish mackerel, perch, bass, croakers (Micropogon undulatus), mullet, menhaden, oysters and clams are caught in the sounds, in the lower courses of the rivers flowing into them, or in the neighbouring waters of the sea.
In the sounds along the coast, in the lower courses of the rivers that flow into them, and along the outer shores fishing is an important industry.
The harbours along the sounds and in the estuaries of the rivers are well protected from the storms of the ocean by the long chain of narrow islands in front, but navigation by the largest vessels is interrupted by shoals in the sounds, and especially by bars crossing the inlets between islands.
Part of these rivers are navigable for small steamers, and the Sao Francisco must some day be of great importance in the development of Central Brazil.
All these rivers of the Brazilian plateau are interrupted by falls and rapids.

The great rivers of northern India - the Ganges, the Brahmaputra and the Indus - all derive their waters from the Tibetan mountain mass; and it is a remarkable circumstance that the northern water-parting of India should lie to the north of the Himalaya in the regions of central Tibet.
In this tract the rainfall is nowhere sufficient for the purposes of agriculture, which is only possible by help of irrigation; and the fixed population (which contains a non-Turkish element) is comparatively small, and restricted to the towns and the districts near the rivers.
Last is the Altai, near the 50th parallel, rising to 10,000 or 12,000 ft., which separates the waters of the great rivers of western Siberia from those that collect into the lakes of northwest Mongolia, Dzungaria and Kalka.
The Ob,Yenisei and Lena,which traverse Siberia, are among the largest rivers in the world.
