Dredging has improved the navigable channel of the river, which is tidal to this point and is lined with quays.

Constant use, increased friction (m o r e especially at high speeds), and damage to the rotator will alter an ascertained log error; head or following seas, strong winds, currents and tidal streams also FIG.

The lake is practically tideless, though true tidal pulsations amounting to 3 in.

Under ordinary conditions the sluices are raised to admit boats to pass from the half flood to half ebb, so that the river remains tidal up to Teddington, the next lock.

This sand has not been brought by the Hudson itself, for that river drops most of its sediment load far up stream, in its long tidal channel.

About two-thirds of the boundary line of Kent is formed by tidal water.

The main watershed follows a tortuous course which crosses the mountainous belt just north of New river in Virginia; south of this the rivers head in the Blue Ridge, cross the higher Unakas, receive important tributaries from the Great Valley, and traversing the Cumberland Plateau in spreading gorges, escape by way of the Cumberland and Tennessee rivers to the Ohio and Mississippi, and thus to the Gulf of Mexico; in the central section the rivers, rising in or beyond the Valley Ridges, flow through great gorges (water gaps) to the Great Valley, and by southeasterly courses across the Blue Ridge to tidal estuaries penetrating the coastal plain; in the northern section the water-parting lies on the inland side of the mountainous belt, the main lines of drainage running from north to south.

Tidal movement is slight.

The channel was called the Wantsume, and its extent may be gathered from the position of the village of Fordwich near Canterbury, which had formerly a tidal harbour, and is a member of the Cinque Port of Sandwich.

Within historic times much of this marsh was covered by the sea, and the valley of the river Rother, which forms part of the boundary of Kent with Sussex, entering the sea at Rye harbour, was represented by a tidal estuary for a considerable distance inland.

Throughout this distance the waters are tidal, and the river is navigable all the year round by boats drawing 6 ft.

The town occupies a narrow beach between the sea and bluffs, and was greatly damaged by an earthquake and tidal wave in 1877.

On the East Shore to the north is a marly loam overlying a yellowish-red clay sub-soil, to the south is a soil quite stiff with light coloured clay, while here and there, especially in the middle and south, are considerable areas both of light sandy soils and tidal marsh loams. On the West Shore the soils range from a light sandy loam in the lower levels south from Baltimore to rather heavy loarns overlying a yellowish clay on the rolling uplands and on the terraces along the Potomac and Patuxent.

The tramway was converted into a railway, and in 1865 opened for passenger traffic. In 1866 a dock (71 acres) and tidal basin (21 acres) were constructed, but since about 1902 they have fallen into disuse and the coal is diverged to other ports, chiefly Port Talbot.

The Piscataqua is a tidal estuary fed chiefly by the Salmon Falls, Lamprey and Exeter rivers.

The extensive Alexandra tidal basin, on the north side of the Liffey, admits vessels of similar capacity.

He also reduced the solar parallax to 14" (less than a quarter of Kepler's estimate), corrected the sun's semi-diameter to 15' 45", recommended decimal notation, and was the first to make tidal observations.

Where drift deposits border the sea, the shore line has been cut back or built forward in beaches of submature expression, often enclosing extensive tidal marshes; but the great part of the shore line is rocky, and there the change from initial pattern due to submergence is as yet small.

This arrangement has been provided at several weirs on the Thames, to afford control of the flood discharge, and reduce the extent of the inundations; the largest of these composite weirs on that river is at the tidal limit at Teddington, where the two central bays, with a total length of 2421 ft., are closed by thirty-five draw-doors sliding between iron frames supporting a foot-bridge, from which the doors are raised by a winch.'

The great earthquake of 1868, followed by a tidal wave, nearly destroyed the town and shipping.

The greatest tidal rise is 13 ft.

The warping which is practised in England is almost exclusively confined to the overflowing of level ground within tide mark, and is conducted mostly within the districts commanded by estuaries or tidal rivers.

But while the wisdom of one age thus succeeded in restricting within bounds the tidal water of the river, it was left to the greater wisdom of a succeeding age to improve upon' this arrangement by admitting these muddy waters to lay a fresh coat of rich silt on the exhausted soils.

It is essentially an inhabitant of tidal waters and estuaries, and often goes out to sea; hence its wide distribution, from the whole coast of Bengal to southern China, to the northern coasts of Australia and even to the Fiji islands.

In tidal seas a " jas " (or storage reservoir) is constructed alongside, similarly rendered impervious, in which the water is allowed to settle and concentrate to a certain extent.

In tidal seas they range from the limits of high water to some distance beyond the low-water line.

The Tyne dock has a water-area of 50 acres, the tidal basin of 10 acres, and the quays and yards about 300 acres.

The tidal harbour is enclosed by stone breakwaters, and large vessels enter and load frozen meat direct from the refrigerator cars.

One necessary effect of the tidal retardation of the earth's rotation is gradually to increase this length.

These rivers approach each other at their mouths, and form a vast network of tidal channels, creeks and islands.

The surface is diversified by vales, meadows, sand-dunes and tidal marshes.

In such a system the tidal forces must be very great, and under their influence the stars will not be spherical, but will be elongated in the direction of the line joining their centres.

When the orbits are eccentric, the tidal disturbance varying with the distance between the two components will probably cause changes in their absolute brilliancy; the variation due to change in the aspect of the system presented to us may thus be supplemented by a real intrinsic variation, both, however, being regulated by the orbital motion.

Tidal action also accounts for the progressively increasing eccentricities of the orbits, already referred to.

The east coast of Korea is steep and rock-bound, with deep water and a tidal rise and fall of 1 to 2 ft.

The west coast is often low and shelving, and abounds in mud-banks, and the tidal rise and fall is from 20 to 36 ft.

These included a tidal basin and, opening out of it, a deep dock and two locks, in themselves serving as large docks, which lead to three basins and four docks.

An entrance was also formed between the new tidal basin and the steam basin of 1848, and large additions were made to the wharfage accommodation as well as to the storehouses and factories.

Under the influence of the intermittent trade-winds Lake Nicaragua rises and falls regularly, whence the popular notion that it was a tidal lake.

Evidences of shallow water conditions arc abundant; very frequently on the bedding surfaces of sandstones and other rocks we find cracks made by the sun's heat and pittings caused by the showers that fell from the Cambrian sky, and these records of the weather of this remote period are preserved as sharply and clearly as those made only to-day on our tidal reaches.

It is only when we come to consider such delicate questions as the influence of tidal friction that other standards become necessary.

In the Gulfs of Suez and Akaba, almost the only part of the Red Sea in which tidal phenomena are well developed, a sharply defined tidal circulation is found.

When the earthquake occurs on the coast, or beneath the sea in its vicinity, tidal waves are sometimes formed, which cause even greater damage than the earthquake itself.

Arica has been three times destroyed by tidal waves, and other small towns of the north Chilean coast have suffered similar disasters.

Coquimbo was swept by a tidal wave in 1849, and Concepcion and Talcahuano were similarly destroyed in 1835.

The great earthquake which partially destroyed Valparaiso in 1906, however, was not followed by a tidal wave.

The common quay was on the west bank; all ships coming in had to lie in the river bed or in a natural tidal basin known as Fabian's Bay, on the east.

A canal connecting the tidal part of the river Neath with the mouth of the Tawb, made in 1789, was in 1824 connected with the Vale of Neath canal by means of an aqueduct across the Neath river, when also a small dock, Port Tennant (so named after its owner) or Salthouse Dock, was made near the east pier, and this continued to be used till 1880.
