Surface-water Sentence Examples

In the hot season there is almost no surface water.

Where the trade-winds heap up the surface water against the east coasts of the continents the currents turn poleward.

In this latter section Spindler ascertained in July 1897 that the temperature of the surface water 60 m.

The tides being lowest on the north coast of the province, the scheme of the Waterstaat, the government department (dating from 1879), provides for the largest removal of superfluous surface water into the Lauwerszee.

When the surface-water of a river is higher than the fields right and left, there is nothing easier than to breach the embankments and flood the fields - in fact, it may be more difficult to prevent their being flooded than to flood them - but in ordinary floods the Nile is never higher than all the bordering lands, and in years of feeble flood it is higher than none of them.

In Cheshire the surface-water trickling through the overlying strata dissolves the salt, which is subsequently pumped as brine, but at Middlesbrough the great depth and impermeability of the strata precludes this, so another method has been resorted to.

Through this space the fresh surface water finds its way, and dissolving the salt below rises in the inner tube as brine, but only to such a level that the two columns bear to one another the relation of ten to twelve, this being the inverse ratio of the respective weights of saturated brine and fresh water.

Hence the best position for a well in the Chalk is generally that over which, if the strata were impermeable, the largest quantity of surface water would flow.

Thus natural or artificial surfaces which are completely permeable to rainfall may become almost impermeable when protected by surface water from drought and frost, and from earth-worms, vegetation and artificial disturbance.

Dams Any well-made earthen embankment of moderate height, and of such thickness and uniformity of construction as to ensure freedom from excessive percolation at any point, will in the course of time become almost impermeable to surface water standing against it; and when permeable rocks are covered with many feet of soil, the leakage through such soil from standing water newly placed above it generally diminishes rapidly, and in process of time often ceases entirely.

The saltest surface water is found in (a) the Arabian Sea and (b) along a belt extending from West Australia to South Africa, the highest salinity in this belt occurring at the Australian end.

South of the belt salinity falls quickly as latitude increases, while to the north of it, in the monsoon region, the surface water is very fresh off the African coast and to the north-east.

Where surface water is adequate the regions of the Pierre shale make splendid grazing lands; but in general they are not very useful for agriculture.

Very generally, especially in the butte regions, the country lends itself to the impounding of surface water.

On that island there are considerable and beautiful streams, but the others generally are badly off for fresh surface water.

The majority of people had no problems with surface water or storm drainage, flood alleviation seems to have lessened the previous problems.

These large areas can produce considerable amounts of surface water runoff in heavy storms.

It may be used for sealing in front of kerbs to prevent surface water egress.

Most of the earth's surface water is permanently frozen or salty.

Selection of Deer control areas Give primary importance to underlying soil type, with preference to surface water gleys and brown earths.

It has rained almost nonstop for three out of the last four days, and the result is a lot of surface water.

For example, in the Atlantic, the Gulf Stream drives warm surface water northwards.

The only use Welsh water had for this pipeline he was informed was during possible surface water outfall.

Often flooding incidents reported to Arun DC relate to a combination of land drainage, highway flooding, and foul or surface water sewerage.

The least expensive option is to construct shallow swales to deflect surface water to less obtrusive sections of the course.

Pesticides enter surface water sources such as lakes and streams through runoff.

In the extreme west the salinity of the surface water is about 36 3 per mille, and it increases eastwards to 37 6 east of Sardinia and 39 0 and upwards in the Levant.

Where surface water is banked up against the land, as by the equatorial and Gulf Stream drift currents, it appears to penetrate to very considerable depths; the escaping stream currents are at first of great vertical thickness and part of the water at their sources has a downward movement.

The fact that spring water is not now found in this locality is by no means fatal to the theory; recent engineering investigations have shown that much of the surface water of the Attic plain has sunk to a lower level.

The temperature is rather remarkable, there being an intermediate cold layer between 25 and 50 fathoms. This is due to the sinking of the cold surface water (which in winter reaches freezing-point) on to the top of the denser more saline water of the greater depths.

The ridge across Denmark Strait west of Iceland nowhere exceeds 300 fathoms in depth, so that the deeper water of the North Polar Basin is effectively separated from that of the Atlantic. A third small basin occupies Baffin Bay and contains a maximum depth of 1050 fathoms. Depths of from loo to 300 fathoms are not uncommon amongst the channels of the Arctic Archipelago north of North America, and Bering Strait, through which the surface water of the Arctic Sea meets that of the Pacific, is only 28 fathoms deep.

Dittmar's analysis of the " Challenger " samples indicated an excess of oxygen in the surface water of high southern latitudes and a deficiency at depths below 50 fathoms.

The observations of Aime in 1845 and of Semmola in the Gulf of Naples in 1881 show that the surface water in winter cools until the whole mass of water from the surface to the bottom, in 1600 fathoms or more, assumes the same temperature.

As the Arctic Basin is shut off from the North Atlantic by ridges rising to within 300 fathoms of the surface and from the Pacific by the shallow shelf of the Bering Sea, and as the ice-laden East Greenland and Labrador currents consist of fresh surface water which cannot appreciably influence the underlying mass, the Arctic region has no practical effect upon the bottom temperature of the three great oceans, which is entirely dominated by the influence of the Antarctic. The existence of deep-lying and extensive rises or ridges in high southern latitudes has been indicated by the deep-sea temperature observations of Antarctic expeditions.

The great warming and abundant rainfall of the island regions of the western Pacific, and the low temperature of the surface water in the east, cause a displacement of the southern tropical maximum of pressure to the east; hence we have a permanent " South Pacific anticyclone " close to the coast of South America.

The cultivation of the cane was greatly encouraged by the Reciprocity Treaty of 1875, which established practically free trade between the islands and the United States, and since 1879 it has been widely extended by means of irrigation, the water being obtained both by pumping from numerous artesian wells and by conducting surface water through canals and ditches.

The Bad Lands are by no means infertile (their name, it should be noted, was originally Mauvaises terres a traverser); but they are almost destitute of ground water, though containing many green " pockets " where surface water can be stored.

Liquid surface water is n't essential to form most of the younger water features.

For underground sewerage or surface water drainage pipes, vitrified clay pipes are suitable.

This influences the temperature of surface water in the world's oceans, and precipitation levels are altered, too.
