There are three jetties, north, east and south.
The present outer harbour covers about 300 acres and is formed by two converging jetties and a breakwater.
Or more by dredging and by the construction of jetties and an immense dam, works which were begun by the state in 1823 but from 1828 were carried on from time to time by the national government.
Long, and with quays and jetties along the Gabbari foreshore.
Harbour works were begun in 1857, piers and jetties were constructed, dredgers imported, and controversy raged over the various schemes for harbour improvement.
Of the outlet of the Straits ready for any move of the Allies in that quarter; but, thanks to a system of jetties erected on either shore at the upper end of the Narrows, and to improved communications, troops could be shifted from side to side of the waterway very rapidly.
If there had been no fighting daring these autumn months worthy of mention, much creditable work had been carried out by the invaders in respect to developing communications and to improving jetties and landing-places, especially at Suvla.
The tempestuous weather, moreover, created serious damage at most of the landing-places, where solidly constructed jetties were in some instances completely demolished by the seas.
The naval authorities had been busy assembling and organizing the available small craft in anticipation of the operation that appeared to be imminent, and jetties damaged in the Nov.
During the daytime reliefs took place as usual, pretences were made of disembarking animals and stores at the jetties, and the result was that the Turks remained in complete ignorance as to what was going on close to their lines.
Long jetties spring out on either side of the entrance, curving round about midway in order to run parallel to the river, thus forming a huge funnelshaped entrance; the eastern jetty forms a landing-stage for passenger traffic and the western is designed for the shipment of bunker and cargo coal.
Tampico and Coatzacoalcos, however, have been improved by breakwaters or jetties, and the deepening of the Channels across the bars, into safe and commodious harbours.
By dredging and the construction of jetties the Federal government has since 1885 greatly improved the channel at the mouth of the river.
Two long jetties or breakwaters have now been constructed, about 350 acres of harbour area have been dredged to a depth of 30 ft., and two wharves of steel and concrete, one 600 ft.
The harbour, built in 9 04-1908, is formed by two jetties, one of 6840 ft., the other of 1968 ft., the entrance being 720 ft.
Some of these are united to the mainland and to each other by jetties which curve round so as to form the Port de Refuge, a haven available only in fair weather.
Over the sill at high water of spring tides; the construction of new jetties at the entrance to the tidal basin and at the north wall; the establishment of a coal wharf with hydraulic appliances; a torpedo range in the harbour; the erection of various buildings such as torpedo and gun-mounting stores, electrical shops and numerous subsidiary works; and extensive dredging of the harbour to increase the berthing accommodation for the fleet.
Respectively at ordinary low tides, and commodious jetties and quays were constructed.
The port has three jetties of wrought iron, respectively 1162, 1152 and 1462 ft.
These jetties are provided with hydraulic cranes, &c., and railways connect them with the main line, so that goods can be sent direct from the jetties to every part of South Africa.
At the same period (1873) the building of the existing jetties was undertaken.
The railway company has constructed jetties at which steamers can discharge their cargo.
In 1894, owing to the constantly increasing size of vessels frequenting the Danube, it was found necessary to deepen the entrance still further, and to construct two parallel piers between the main jetties, reducing the breadth of the river to 500 ft., and thereby increasing the scour.
Two jetties enclose a channel leading into the river, which forms a tidal basin with a depth at neap-tides of 24 ft.
Into the sea, and is composed of Norwegian granite and Belgian limestone, strengthened at intervals by projecting jetties of piles and fascines.
In severe storms the water near shore is filled with sand, which is deposited where the currents are checked around the ends of jetties in such a way as to form bars out into the lake across improved channels.
Duluth, Superior, Port Wing, Wis., Ontonagon, Mich., and Grand Marais, Mich., are harbours with entrances formed by parallel jetties extending across obstructing bars.
Daux, discovered the jetties and the moles of the commercial harbour, and the line of the military harbour (Cothon); both harbours, which were mainly artificial, are entirely silted up. There remains a fragment of the fortifications of the Punic town, which had a total length of 6410 metres, and remains of the substructions of the Byzantine acropolis, of the circus, the theatre, the water cisterns, and of other buildings, notably the interesting Byzantine basilica which is now used as an Arab cafe (Kahwat-el-Kubba).
