A jetty is a man-made structure that protrudes from land out into water. A jetty may serve as a breakwater, as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word ', "thrown", signifying something thrown out. For regulating rivers Wing dams Jetties of one form, wing dams, are extended out, opposite one another, from each bank of a river, at intervals, to contract a wide channel, and concentrate the current to deepen the channel. At the outlet of tideless rivers Jetties have been constructed on each side of the outlet river of some of the rivers flowing into the Baltic, with the objective of prolonging the scour of the river and protecting the channel from being shoaled by the littoral drift along the shore. Another application of parallel jetties is in lowering the bar in front of one of the mouths of a deltaic river flowing into a tide — a virtual prolongation of its less sea, by extending the scour of the riv ...

Great Yarmouth
Great Yarmouth ( ), often called Yarmouth, is a seaside resort, seaside town which gives its name to the wider Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located east of Norwich. Its fishing industry, mainly for herring, shrank after the mid-20th century and has all but ended. North Sea oil from the 1960s supplied an oil rig industry that services offshore natural gas rigs; more recently, offshore wind power and other renewable energy industries have ensued. Yarmouth has been a resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Holidaymaking rose when a railway opened in 1844, bringing easier, cheaper access and some new settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth boomed as a resort, with a promenade, pubs, trams, fish-and-chip shops, theatres, the Great Yarmouth Pleasure Beach, Pleasure Beach, the Sea Life Centres, Sea Life Centre, the Great Yarmouth Hi ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be composed ...

Lock (water Transport)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Openwork
In art history, architecture, and related fields, openwork or open-work is any decorative technique that creates holes, piercings, or gaps through a solid material such as metal, wood, stone, pottery, cloth, leather, or ivory. Such techniques have been very widely used in a great number of cultures. The term is rather flexible, and used both for additive techniques that build up the design, as for example most large features in architecture, and those that take a plain material and make cuts or holes in it. Equally techniques such as casting using Molding (process), moulds create the whole design in a single stage, and are common in openwork. Though much openwork relies for its effect on the viewer seeing right through the object, some pieces place a different material behind the openwork as a background. Varieties Techniques or styles that normally use openwork include all the family of lace and cutwork types in textiles, including broderie anglaise and many others. Fretwork in ...

Dock (maritime)
The word dock () in American English refers to one or a group of human-made structures that are involved in the handling of boats or ships (usually on or near a shore). In British English, the term is not used the same way as in American English; it is used to mean the area of water that is next to or around a wharf or quay. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard (also known as a shipyard) where the loading, unloading, building, or repairing of ships occurs. History The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor, of Pharaoh Khufu#Wadi al-Jarf, Khufu, dating from c.2500 BC located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BC and was located away from the main current (water), current to avoid deposition of silt. Modern oceanographers have observed that the ancient Indu ...

Fascine Mattress
A fascine mattress , literally sink piece), is a large woven mat made of wikt:brushwood, brushwood, typically willow twigs and shoot (botany), shoots, used to protect riverbeds and other underwater surfaces from Hydrodynamic scour, scour and erosion. They are similar in construction to a fascine, but are primarily used for hydraulic engineering works, typically to strengthen the banks of rivers and streams, as well as coastal structures like revetments and groynes. Modern fascine mattresses utilise a layer of geotextile in order to fulfill the competing requirements of water Permeability (Earth sciences), permeability balanced with the need to be impervious to sand. Prior to the advent of synthetic geotextiles in the 1960s, a layer formed from Reed (plant), reeds was incorporated to make the fascine mattress sand-tight. Fascine mattresses have been used worldwide, but are particularly common in The Netherlands, where significant expertise in their preparation and construction i ...

Meuse (river)
The Meuse or Maas is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301, the upper Meuse roughly marked the western border of the Holy Roman Empire with the France in the Middle Ages, Kingdom of France, after Count Henry III, Count of Bar, Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV of France, Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III, Duke of Bavaria, John III against the citizens of Liège, who were in open revolt. After the Battle of Othée, battle, which saw the men from Liège defeated, John ordered the drowning in the Meuse of burghers and noblemen in Liège whose loyalties he suspected. The border remained relatively stable until the annexation of the Three Bishoprics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
