American Rural Highways Total renewable water resources: This entry provides the long-term average water availability for a country in cubic kilometers of precipitation, recharged ground water, and surface inflows from surrounding countries. The 2008 CIA World Factbook Ground moisture is derived partly from the evaporation of the ground water and its capillary absorption by the surface soil, and partly by the retention of water from rains upon the surface. The Home Medical Library, Volume V (of VI) Both calcium carbonate and calcium phosphate are soluble in ordinary ground waters, but the carbonate is the more soluble of the two. The Economic Aspect of Geology A system of drainage by which the ground water was brought to the same level under both stables made them equally healthful. Rural Hygiene The remedy in both cases is tile underdrains alongside the road to lower the ground water level so that it cannot affect the road surface. American Rural Highways This water in the earth, or ground water, is of very great importance. Conservation Reader Subsoil Drainage.—By subsoil drainage is meant the reducing of the level of the ground water by draining all subsoil water into certain water courses, either artificial or natural. The Home Medical Library, Volume V (of VI) Only a very small part of the central region can be reclaimed; for where there is so little rain there can be but little either of surface or of ground waters. Wealth of the World's Waste Places and Oceania These pipes may run fifty or one hundred feet each way from the main spring, so long as they continue to find ground water. Rural Hygiene Similarly, the higher head of the underground water near the top of a hill may result in ground water coming quite close to the surface some distance down the hill. American Rural Highways We went down some eighteen feet or so, near the ground water, and can report as follows, viz., the top layer consisted of about two and a half feet of extraordinary hard and compacted soil. The Journal of Negro History, Volume 6, 1921 The level of the ground water depends upon the underlying strata, and also upon the movements of the subterranean water bed. The Home Medical Library, Volume V (of VI) A site on clay soil, or where the ground water approaches the surface, is damp, cold, and unhealthful. Infantry Drill Regulations, United States Army, 1911 Corrected to April 15, 1917 (Changes Nos. 1 to 19) The writer has seen a six-inch underdrain running full of ground water collected within a distance of a hundred feet, but this was in gravel soil through which the water passed very freely. Rural Hygiene The function of the tile drains in such cases is precisely the same as when employed in land drainage; to lower the ground water level. American Rural Highways A large portion of this helps to cause the slow rock-decay that forms the soil, and which is known as ground water. Checking the Waste A Study in Conservation In marshy land the ground water is at the surface; in other places it can be reached only by deep borings. The Home Medical Library, Volume V (of VI) Around the metropolis, some ground water is being taken from wells even now to supplement the overall supply and to satisfy the whole demand of any number of outlying communities. The Nation's River A report on the Potomac from the U.S. Department of the Interior The question of installing underdrains will arise only in cases where the ground water, always to be found below the surface somewhere, comes up so high as to affect the disposal of sewage. Rural Hygiene Sometimes the ground water encounters an impervious stratum as it flows downward through the soil, or one that is less pervious than the surface soil. American Rural Highways Next to these the best crops are grown where congenial soils are underlaid with ground water, not too near nor too distant from the surface. Clovers and How to Grow Them The movements of the ground water are in two directions—horizontal and vertical. The Home Medical Library, Volume V (of VI) A future possibility, if research presently going on in the Basin verifies it and shows ways of putting it to use, is to employ ground water in the same way. The Nation's River A report on the Potomac from the U.S. Department of the Interior We can imagine the ceaseless corrosion due to the ground water, bringing about a constant though slow descent of the whole surface. Outlines of the Earth's History A Popular Study in Physiography It is sometimes called ground water or standing water and flows under the influence of gravity. The First Book of Farming The amount of water required will vary with the soil, the season of the year, the distance of the ground water from the surface, and the precipitation. Clovers and How to Grow Them The vertical motion of the ground water is to and from the surface, and is due to the amount of rainfall, the pressure of tides, and water courses into which the ground water drains. The Home Medical Library, Volume V (of VI) The real activity of ground water is due to its great solvent power; every time we put sugar into tea or soap into water we are using water as a solvent. General Science The proportion of these two classes, the surface and the ground water, varies greatly, and an intermixture of them is continually going on. Outlines of the Earth's History A Popular Study in Physiography Fluctuations in the level of ground water, especially if great and sudden, generally cause ill-health among the residents. Scientific American Supplement, No. 455, September 20, 1884 Where the ground water is deep a wind mill and storage tank would be desirable. The Dollar Hen The water of springs is subterranean, or ground water, which for geological reasons has found a natural outlet on the surface. The Home Medical Library, Volume V (of VI) Rain water, coming as it does from the clouds, is free from the chemicals gathered by ground water, and is hence practically pure. General Science The soil down to the limit of the ground water contains a large amount of air. Scientific American Supplement, No. 362, December 9, 1882 In the portion of the dry-farm territory where the rainfall approximates twenty inches, this problem is not so very difficult, since ground water may be reached easily. Dry-Farming : a System of Agriculture for Countries under a Low Rainfall Are these wells fed by water from the river percolating through the sand, or by ground water on its way to the stream and possibly contaminated with the sewage of the town? The Elements of Geology The above explanation will be helpful in pointing out how, in some cases, spring water may be nothing but contaminated ground water. The Home Medical Library, Volume V (of VI) By studying a spring one may learn much of the ways and work of ground water. The Elements of Geology In arid lands where ground water is drawn by capillarity to the surface and there evaporates, it leaves as surface incrustations the minerals held in solution. The Elements of Geology In countries where the rainfall is 30 inches or over, and in many places where the rainfall is considerably less, the water drains through the soil into the standing ground water. Dry-Farming : a System of Agriculture for Countries under a Low Rainfall Near the surface, where the circulation of ground water is most active, it oxidizes, corrodes, and dissolves the rocks through which it passes. The Elements of Geology A well should always be placed above the source of pollution, using the word "above" with reference to the direction in which the ground water flows. The Home Medical Library, Volume V (of VI) So both rain and ground water are charged with active chemical agents, by the help of which they corrode and rust and decompose all rocks to a greater or less degree. The Elements of Geology Evaporating beneath the surface, ground water may deposit a limy cement in beds of loose sand and gravel. The Elements of Geology Although to some extent the soluble waste of rocks is washed down surface slopes by the rain, by far the larger part is carried downward by ground water and is delivered to streams by springs. The Elements of Geology The absence of layers of insoluble or impervious rock in its structure allows a free circulation of ground water within it by the way of all natural openings in the rock. The Elements of Geology The source of the ground water is the rainfall, part of which drains into the porous soil until it reaches an impermeable stratum, where it collects. The Home Medical Library, Volume V (of VI) The zone in which the work of ground water is thus for the most part destructive we may call the zone of solution. The Elements of Geology Karst, the name of a part of this country, is now used to designate any region or landscape thus sculptured by the chemical action of surface and ground water. The Elements of Geology Below a depth of even three or four miles it is believed that ground water cannot circulate. The Elements of Geology Seeping through the mantle of waste, ground water soaks into the pores and crevices of the underlying rock. The Elements of Geology Compounds of iron have been taken into solution by ground water from soil and rocks, and are now changed to the insoluble oxide on exposure to the oxygen of the air. The Elements of Geology In wet ground iron compounds leached by ground water from the soil often collect in reddish deposits a few feet below the surface, where their downward progress is arrested by some impervious clay. The Elements of Geology So slow is the movement of ground water through the rocks that even during long droughts large amounts remain stored above the levels of surface drainage. The Elements of Geology The work of ground water in producing landslides has already been noticed. The Elements of Geology In dry climates permanent ground water may be found only at depths of hundreds of feet. The Elements of Geology Even when gathered into definite channels, ground water does not have the erosive power of surface streams, since it carries with it little or no rock waste. The Elements of Geology Along its base the ground water of the neighboring land finds its natural outlet in springs which under mine it. The Elements of Geology The minerals of veins are therefore constantly being dissolved along their upper portions and carried down the fissures by ground water to lower levels, where they are redeposited. The Elements of Geology They contribute to the ground water of the region instead of being increased by it. The Elements of Geology |
