Stream (water)

“ Seen from a distance the water seems at first sight, when the broad stream fills the vision as a whole, to flow with smooth, even current between meadow and cornfield. But, coming to the brink, that silvery surface now appears exquisitely chased with ever-changing lines. The light airs, wandering to and fro where high banks exclude the direct influence of the breeze, flutter the ripples hither and thither, so that, instead of rolling upon one lee shore, they meet and expend their little force upon each other. ”

“ Then, as he staggered toward this green-bordered pond and that crystal-blue lake, already drinking and laving in his mind, he began to hear the beautiful sounds of falling rain, of gurgling brooks, of lapping waves, of roaring rapids, of gentle river currents, of water—water—water sweetly tinkling and babbling, of wind-laden murmur of a mountain stream. ”

“ More mobile and more searching than ice or rock rubbish, the trickling drops are guided by the deepest lines of the hillside in their incipient flow, and as these River systems. lines converge, the stream, gaining strength, proceeds in its torrential course to carve its channel deeper and entrench itself in permanent occupation. Thus the stream-bed, from which at first the water might be blown away into a new channel by a gale of wind, ultimately grows to be the strongest line of the landscape. ”

“ At our feet a stream was struggling with the multitude of rude rocks, which Nature, in one of her primeval convulsions, had flung here and there in masses into its current; sometimes uniting into irregular ledges, over which the water swept with impetuosity;—sometimes standing insulated in the stream, and increasing the energies of the river by their resistance;—sometimes breaking forward from the bank, and giving a bolder effect to its romantic outline. ”

“ It is pleasanter to think of not unsuccessful days by lowland or highland streams, when the sun was veiled, the sky pearly grey, the water, as the people say, in grand order. There is the artistic excitement of choosing the hook, gaudy for a heavy water, neat and modest for a clearer stream. There is the feverish moment of adjusting rod and line, while you mark a fish “rising to himself.” You begin to cast well above him, and come gradually down, till the fly lights on the place where he is lying. ”

“ The clusters next the stream droop over till their graceful plumes touch the surface of the water, and, as the plants grow older, they droop lower, until the stream is filled with a yielding mesh of canes. ”

“ A stream may acquire the name of a river, in the channel of which, at some seasons of extreme drought, no water flows. For a great portion of the year parts of a stream may flow in great abundance, in which, during a very dry season, we may find only standing pools. It would be against all usage to say that the general source of the river was at that point in its channel from which the water always flows. ”

“ In a little hollow of the stream, below the waterfalls, where the falling water has churned out a basin for itself, we sometimes see a trout, silvery bellied, and dark of back, with spots along his sides. But the place where we go to look for fish and other water folk is farther down the stream, below the wood and moorland. ”

“ The stream is not perceived till you stand on the very edge. Its bed is between 300 and 400 yards broad, and is about 200 or 300 feet below the average surface of the table-land. The body of water which forms this river is very inconsiderable, and becomes more and more so as it nears the sea. ”

“ In the dry season the stream runs at the bottom of a narrow and deep groove, whose sides are polished and fluted by the boiling action of the water in flood, like the rims of ancient Eastern wells by the draw-ropes. The breadth of the groove is often not more than from forty to sixty yards, and it has some sharp turnings, double channels, and little cataracts in it. As we steamed up, the masts of the "Ma Robert," though some thirty feet high, did not reach the level of the flood-channel above, and the man in the chains sung out, "No bottom at ten fathoms." ”

“ A part of the rain-water is there held, until it returns by evaporation, to the clouds, while a part slowly percolates downward, finding its way into swamps and springy plains, and finally, after days or weeks of wandering, slowly, but surely, finds its outlet in the stream or pond. ”

“ They paddle to a shallow part of the stream, where it flows under grassy banks, a place where the bottom is a little muddy, instead of being covered with small round pebbles. Then they stand and look into the water, up stream, for the ripples flowing from their ankles make it impossible to see into the water clearly if they look the other way. ”

“ But, frequently, a very large marsh is traversed by a tortuous stream which occupies a large area, and which, although the tidal water which it contains gives it the appearance of a river, is only the outlet of an insignificant stream, which might be carried along the edge of the upland in an ordinary mill-race. ”

“ The stream whose water spreads over its low banks is without depth and current and power. But confine the waters between high, narrow banks, the bed of the stream is deepened, and its mighty current supports animal life and turns the wheels of mill and factory. ”

“ This wave has first to overcome the water flowing down the river, which is acting in opposition to it, and in so doing causes a banking up of the water to such a height that the inclination of the surface is reversed to an extent sufficient to cause a tidal current to run up the river. The momentum acquired by the water passing up-stream carries it to a higher level towards the head of the river than at the mouth, and, similarly, in returning, the water flowing down the river gains sufficient impetus to scoop out the water at the mouth and form a low water below that in the sea adjoining. ”

“ OTHER WATER BORDERS It is the proper destiny of every considerable stream in the west to become an irrigating ditch. It would seem the streams are willing. They go as far as they can, or dare, toward the tillable lands in their own boulder fenced gullies—but how much farther in the man-made waterways. ”

“ Water is found only in certain streams and in single springs, and is very valuable. Of course, any good road which is {68} required has to follow the line of water, but the rivers commence to flow at any point in the river-bed, and after becoming a rushing torrent, disappear as suddenly as they arose, into the ground and are seen no more; where they go to no one knows, but you may seek in vain further down the bed of the river and not find water. In some cases the water reappears in the stream ten miles lower down, and disappears again as before. ”

“ A river that spreads out into the indeterminate earthform of a marsh is an effective barrier; but one that gathers waters into a natural basin and forms a lake retains the uniting power of a navigable stream and also, by the extension of its area and elimination of its current, approaches the nature of an enclosed sea. Mountain rivers, characterized by small volume and turbulent flow, first become navigable when they check their impetuosity and gather their store of water in some lake basin. ”

“ A stream is water falling down hill with a velocity depending upon the inclination of its bed. As it falls it acquires momentum and, hence, energy; and thus a mountain stream, suddenly swollen by rain or melting snow, will tear away masses of rock and sweep everything before it. Nothing can look softer or more harmless than a calm sea, but if the wind sweeping over its surface puts the water in motion, it strikes upon the shore with terrific force ”

“ While the stream is often turbid with surface waste washed into it by rains, the spring remains clear; its water has been filtered during its slow movement through many small underground passages and the pores of rocks. Commonly the spring differs from the stream in that it carries a far larger load of dissolved rock. Chemical analysis proves that streams contain various minerals in solution, but these are usually in quantities so small that they are not perceptible to the taste or feel. ”

“ About two hundred yards below us, the stream rushed with an astonishing but silent velocity, between perpendicular rocks, which are not more than thirty-five yards asunder: when the water is high, it runs over those rocks, in a channel three times that breadth, where it is bounded by far more elevated precipices. ”

“ Alteration of Depth or Water-Level.—When the width of a stream is altered, the depth of water—the gradient being supposed to be unchanged—must alter in the opposite manner. A narrowing of the channel by training necessitates an increase in the depth of water, and the same remark applies if an arm of the stream is closed. The increase in depth may be effected either by raising the water-level or by lowering the bed—as may be convenient—or both. If the bed is to be lowered and is of hard clay, it may be necessary to dredge it and, when this has been done, training may be unnecessary. ”

“ They flow between low, rounded hills, and are joined by quiet streams, that occupy the separating grooves between the hills. This is the oldest type of river. It has done its work. Rainfall and stream-flow have brought the level of the land nearly to the level of the stream. Very little more is left to be ground down and carried away. The landscape is beautiful, but it is no longer picturesque. Wind and water have smoothed away unevennesses. Trees and grass and other vegetation check erosion, and the river has little to do but to carry away the surface water that falls as rain. ”

“ If the stream receives no water of another kind, or scarcely any, not only the rivers, but likewise the lakes which receive these waters, are of the same nature as the springs, and serve the same uses ”

“ With favorable conditions, as a stream carrying abundance of fine silt, the water moving sluggishly over the inundated surfaces will drop its earthy burden upon them in thin, loose layers, evenly at first, but, as shallows are formed, irregularly modified, or as sudden freshets produce stronger currents, eddies and ripple-bars gather or disturb the sediment. New lands in wet banks and knobs will begin to appear over the highest ridges. ”

“ For about two hundred miles from its mouth, it has many long and narrow lakes, of about the width of the river itself; and probably they were formerly its channel. These lakes generally have an outlet into the river, [Pg 87] and these so much resemble it, that a person not well acquainted with the stream, would be puzzled to know what channel to take. The river occupies too much ground for its quantity of water, and for about half of the year, it is a difficult stream to navigate. ”

“ If it shall be found that nearly all the rainfall should go into the soil and thence into the under-drainage, coming out slowly and steadily by seepage and by springs into the streams, clear and pure, these streams should present nearly ideal conditions for water-food, for water-power and for stream-navigation. An ideal solution of the soil problem may therefore solve the greater part of the whole complex of problems of which navigation is the last term. ”

“ In arid regions the ground-water surface lies so low that for the most part stream ways do not intersect it. Streams therefore are not fed by springs, but instead lose volume as their waters soak into the thirsty rocks over which they flow. They contribute to the ground water of the region instead of being increased by it. Being supplied chiefly by the run-off, they wither at times of drought to a mere trickle of water, to a chain of pools, or go wholly dry, while at long intervals rains fill their dusty beds with sudden raging torrents. ”

“ The course of water flowing underground is not strictly analogous to that of rivers on the surface, there being, in the one case, a constant descent from a higher to a lower level from the source of the stream to the sea; whereas, in the other, the water may at one time sink far below the level of the ocean, and afterwards rise again high above it. ”

“ Other rills meet this, and form a larger stream, which is called a brook or creek.
As the brook flows on, it is joined by other streams, until, little by little, it becomes a wide and deep river on which large boats may float. At last, it finds its way into the ocean.
Where a river begins is its source. The place where it flows into another body of water is called its mouth. The land over which it flows is its bed.
A river has two banks. As we go toward its mouth, the right bank is on our right hand, and the left bank is on our left. ”

“ Somewhat farther there is a curl upon the water, not constant, but coming every few seconds in obedience to the increase or decrease of the volume of the stream, which there meets with some slight obstacle out of sight. ”

“ In rising one foot a lake may store away more water than the river by its consequent rise at the point of outflow will carry away in many months, and this for the simple reason that the lake may be many hundred or even thousand times as wide as the stream. Moreover, as before noted, the sediment gathered by the stream above the level of the lake is deposited in its basin, and does not affect the lower reaches of the river. ”

“ We measure what is flowing above the bed, but there is more beneath. It sinks down till retained by some impervious stratum, and may become something like a second river flowing under the larger one which we see. It happens sometimes that the whole of a small stream sinks into porous soil and disappears, and, if a retentive stratum which it meets beneath comes out to the surface at a lower part of its course, the filtered water will pour out and become a surface river again, after the ordinary manner of streams. ”
