definition

When the whole of the sediment is on the cork, the iron clip, with which the latter is kept in position, is removed for a moment, and the force of the wine ejects the sediment and cork simultaneously.

Over time, more and more layers of sediment built up and gradually hardened into rock.

The stream is heavily charged with sediment, and from that circumstance got its ancient epithet of flavus (tawny).

On account of the rapid deposition of sediment near the main channel at times of overflow, the flood plain, as is normally the case on mature valley floors, has a lateral slope of as much as 5, 10, or even 12 ft.

In the Tay, Forth and Clyde, where important harbours are situated, great expense is involved in constantly dredging to remove the sediment continually brought down from the land and carried backwards and forwards by the tides.

The Italian shore is generally low, merging, in the north-west, into the marshes and lagoons on either hand of the protruding delta of the river Po, the sediment of which has pushed forward the coast-line for several miles within historic times.

In prosecuting the study of this part of British geology it is soon discovered, and it is essential to bear in mind, that, during the Carboniferous period, the land whence the chief supplies of sediment were derived rose mainly to the north and north-west, as it seems to have done from very early geological time.

Piercing the desert, and at its annual overflow depositing rich sediment brought from the Abyssinian highlands, the river has created the Delta and the fertile strip in Upper Egypt.

When the slope down which a river runs has become very slight, it is unable to carry the sediment brought from higher regions nearer its source, and consequently the lower portion of the river valley becomes filled with alluvial deposits; and since in times of flood the rush of water in the high regions tears off and carries down a greater quantity of sediment than usual, the river spreads this also over the lower valley where the plain is flooded, because the rush of water is checked, and the stream in consequence drops its extra load.

The bottles, which up till now have been in a horizontal position, are then, in order to prepare them for the next process, namely, that known as disgorging, placed in a slanting position, neck downwards, and are daily shaken very slightly, so that by degrees the sediment works its way on to the cork.

The soils in the southern part of Arizona are mainly sandy loams, varying from light loam to heavy, close adobe; on the plateaus is what is known as " mesa " soil; and along the rivers are limited overflow plains of fine sediment - especially along the Colorado and the river Verde.

Intertidal and subtidal sediment biotopes may cover very extensive areas of shore or seabed.

In exceptional cases, when a strong deep current does flow over a rise, as in the case of the Wyville Thomson Ridge, the bottom is swept clear of fine sediment.

Thus a fall in the gradient at any point in the course of a stream; any snag, projection or dam, impeding the current; the reduced velocity caused by the overflowing of streams in flood and the dissipation of their energy where they enter a lake or the sea, are all contributing causes to alluviation, or the deposition of streamborne sediment.

Hwang Ho = Yellow river, Missouri = Big Muddy, the Red river, &c. It has been estimated that the Mississippi annually carries 4064 million tons of sediment to the sea; the Hwang Ho 796 million tons; the Po 67 million tons.

This again depends upon the fertilizing sediment brought down by the Nile and the measure in which lands beyond the natural reach of the flood water can be rendered productive by irrigation.

Flood plains may be the result of planation, with aggradation, that is, they may be due to a graded river working in meanders from side to side, widening its valley by this process and covering the widened valley with sediment.

This fermentation proceeds throughout the summer months, and in the meantime a sediment which adheres to the side of the bottle is gradually formed.

Château After the sediment has been removed the wine is subjected to dosage, or liqueuring.

The process is of course observed by means of the microscope, but the clumps soon settle in the fluid and ultimately form a sediment, leaving the upper part clear.

Most frequently they occur lying on the bedding planes of black shales; less commonly they are met with in many other kinds of sediment, and when in limestone they may retain much of their original relief and admit of a detailed microscopic study.

It has been suggested that where there is low sediment supply mangrove accretion may not be able to keep pace with projected sea-level rises.

The soft sediment infauna may include amphipods, polychaete worms, bivalves and echinoderms.

This is a wide sandy beach with a narrow backshore berm of coarser sediment supplied from local erosion of high sandstone and breccia cliffs.

The second black box was recovered the next day despite being buried in sediment without any traces being visible on the seabed.

Some modern brachiopods have rootlets, but they spread out into soft sediment, just as plant roots do.

River channel confluences are ubiquitous features of all fluvial networks & represent sites of complex, three-dimensional flow & sediment dynamics.

The optimum standards for tracing inorganic contaminants in soil, sediment, water, oil, plants and food materials.

Sediment supply, relative to fluvial transport capacity, has therefore a potentially decisive effect on the erosive power of any bedrock river.

An important part of the project will be to understand how sediment diagenesis affects the anisotropy of shales.

You are letting all the yeast, and colliodal sediment dorp out and letting the CO2 escape.

But how does a traditional barrel of beer with sediment remain drinkable on a moving train?

My thesis title is Studies on the biogenic mediation of sediment dynamics in coastal systems.

This may represent sediment supplied by cliff erosion being entrained by the westward flowing recirculating eddy (Dyer, 1971 ).

Sediment accumulations within groin embayments at Hamworthy Park also indicate a net west to east drift.

The fluvial facies dominates the basal sediment portion that is overlain by an aeolian interval.

Sediment exposures generally show well-sorted and interbedded sand and gravel facies typical of a glaciolacustrine depositional environment.

The aim was to survey the habitat resource and to characterize the sediment types favored by the specialist invertebrate fauna.

These daily gaging stations provide the best information available on sediment flux in the Nation's rivers.

The copper element distribution map, shown here, is one example of the analysis of the inorganic geochemistry of the sediment.

Gully pots The primary purpose of gully pots The primary purpose of gully pots is to trap sediment associated with road run-off.

These include local wave climate; sources of sediment feed and the role of coastline orientation in creating an anticlockwise tidal gyre.
