88-518: The Port of Dover is a cross-channel ferry, cruise terminal, maritime cargo and marina facility situated in Dover , Kent , south-east England . It is the nearest English port to France, at just 34 kilometres (21 mi) away, and is one of the world's busiest maritime passenger ports, with 11.7 million passengers, 2.6 million lorries, 2.2 million cars and motorcycles and 80,000 coaches passing through it in 2017, and with an annual turnover of £58.5 million

176-657: A beam of 36.8 metres (121 ft) and 122,400 gross tons . The cruise ship terminal can accommodate up to three ships at any one time. In 2019 the Port of Dover accommodated 130 cruise ship port calls and over 200,000 passengers, making it the second busiest cruise ship port in the United Kingdom after the Port of Southampton . Dover Cargo Terminal West opened in December 2019, replacing berthing and handling facilities at

264-599: A Travelodge Hotel and a Cineworld Cinema. The Dover Harbour Board is the responsible authority for the running of the Port of Dover. The English Channel , here at its narrowest point in the Straits of Dover, is the busiest shipping lane in the world. Ferries crossing between here and the Continent have to negotiate their way through the constant stream of shipping crossing their path. The Dover Strait Traffic Separation Scheme allots ships separate lanes when passing through

Duke of York's Royal Military School is a selective secondary school with academy status and England's only military boarding school for children of service personnel (co-education ages 11–18), located next to the former site of Connaught Barracks . Non-selective secondary schools There are fjewwr ex- secondary modern mixed schools in Dover, all with academy status . Astor Secondary School federated with St Radigunds Primary School (then renamed White Cliffs Primary College for

616-415: A natural barrier against future disasters like the 2004 Indian Ocean earthquake . Studies have found that an offshore tsunami wall could reduce tsunami wave heights by up to 83%. The appropriate seawall design relies on location-specific aspects, including surrounding erosion processes. There are three main types of seawalls: vertical, curved, stepped, and mounds (see table below). A report published by

704-541: A problem as it is not easy for people to predict or imagine the strength of hurricane or storm-induced waves compared to normal, expected wave patterns. An extreme event can dissipate hundreds of times more energy than everyday waves, and calculating structures that will stand the force of coastal storms is difficult and, often the outcome can become unaffordable. For example, the Omaha Beach seawall in New Zealand

792-402: A rise of between +16-19.3 cm throughout 1900–1988. Superstorm Sandy of 2012 is an example of the devastating effects rising sea levels can cause when mixed with a perfect storm. Superstorm Sandy sent a storm surge of 4–5 m onto New Jersey's and New York's barrier island and urban shorelines, estimated at $ 70 billion in damage. This problem could be overcome by further modeling and determining

880-443: A seawall can be from the area's natural water-table , rain percolating into the ground behind the wall and waves overtopping the wall. The water table can also rise during periods of high water ( high tide ). Lack of adequate drainage can cause the seawall to buckle, move, bow, crack, or collapse. Sinkholes may also develop as the escaping water pressure erodes soil through or around the drainage system. Extreme events also pose

This contrasts with the nearby Channel Tunnel , the only fixed link between the island of Great Britain and the European mainland, which now handles an estimated 20 million passengers and 1.6 million trucks per year. The modern port facility features a large artificial harbour constructed behind stone piers and a defensive concrete breakwater. The port is divided into two main sections:

1144-499: A £330m investment in the area. It has also been a point of destination for many illegal migrant crossings. The Port of Dover provides much of the town's employment, as does tourism including to the landmark White Cliffs of Dover . There were over 368,000 tourists visiting Dover castle in the year of 2019. Dover is classified as a Large-Port Town, due to its large volumes of port traffic and low urban population. Archaeological finds have shown that there were Stone Age people in

1232-481: Is a static feature which can conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea. The table below summarizes some positive and negative effects of seawalls which can be used when comparing their effectiveness with other coastal management options, such as beach nourishment . Generally, seawalls can be a successful way to control coastal erosion, but only if they are constructed well and out of materials that can withstand

1320-693: Is a town and major ferry port in Kent , South East England . It faces France across the Strait of Dover , the narrowest part of the English Channel at 33 kilometres (21 mi) from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone . The town is the administrative centre of the Dover District and home of the Port of Dover . Archaeological finds have revealed that

1408-545: Is also a major issue with seawalls. In 2013, more than 5,000 feet (1,500 m) of seawall was found to be crumbling in Punta Gorda, Florida . Residents of the area pay hundreds of dollars each year for a seawall repair program. The problem is that most of the seawalls are over a half-century old and are being destroyed by only heavy downpours. If not kept in check, seawalls lose effectiveness and become expensive to repair. Seawall construction has existed since ancient times. In

1496-490: Is an adaptation of the English name Dover . The current name was in use at least by the time of Shakespeare's King Lear (between 1603 and 1606), in which the town and its cliffs play a prominent role. Louis VIII of France landed his army, seeking to depose King Henry III , on Dover's mainland beach. Henry III ambushed Louis' army with approximately 400 bowmen atop The White Cliffs of Dover and his cavalry attacking

1584-613: Is believed to be a 100-meter row of boulders in the Mediterranean Sea off the coast of Israel. Boulders were positioned in an attempt to protect the coastal settlement of Tel Hreiz from sea rise following the last glacial maximum . Tel Hreiz was discovered in 1960 by divers searching for shipwrecks, but the row of boulders was not found until storms cleared a sand cover in 2012. More recently, seawalls were constructed in 1623 in Canvey Island , UK, when great floods of

2024-440: Is possible along the coast, since the cliffs are on the sea's edge. The railway, being tunnelled and embanked, skirts the foot of the cliffs. Dover has an oceanic climate (Köppen classification Cfb ) similar to the rest of the United Kingdom with mild temperatures year-round and a light amount of rainfall each month. The warmest recorded temperature was 37.4 °C (99.3 °F), recorded at Langdon Bay on 25 July 2019, While

2112-491: The 2004 Indian Ocean earthquake tsunami crashed against India's south-eastern coastline killing thousands. However, the former French colonial enclave of Pondicherry escaped unscathed. This was primarily due to French engineers who had constructed (and maintained) a massive stone seawall during the time when the city was a French colony. This 300-year-old seawall effectively kept Pondicherry's historic center dry even though tsunami waves drove water 24 ft (7.3 m) above

2200-809: The Dover Western Heights . In the Roman era a walled town was built on the West Bank of the River Dour and the port grew into an important military, mercantile and cross-channel harbour. Dubris was one of the principal starting points of the Roman road later known as Watling Street . Dover grew further after the Norman invasion of 1066 as a member of the Confederation of Cinque Ports . After

2288-422: The Roman occupation of Britain , the port has always enjoyed a significant strategic position due to its proximity to continental Europe and as the location of the sheltered River Dour estuary between two imposing chalk cliffs. The development of the port led directly to the growth of Dover as a settlement and, over many centuries, to the building of extensive defensive fortifications including Dover Castle and

2376-647: The Saxon Shore Way and the North Downs Way . The National Trust White Cliffs can be reached by foot from the town centre, with pathways to South Foreland Lighthouse , and St Margarets Bay along the cliff top . The walking routes from Dover pass the National Trust visitor centre on the landmark chalk cliffs overlooking the English Channel with views of France visible on a clear day. Two National Cycle Network routes begin their journey at

Southeastern trains run from Dover Priory to London Charing Cross , London Victoria or London St Pancras International stations in London, and Ramsgate or Sandwich in Kent. With the introduction of the high-speed service into St Pancras International via High Speed 1 , rail journey times between London and Dover were reduced to 55 minutes non-stop. The Chatham Main Line into Priory

2552-500: The UK , seawall also refers to an earthen bank used to create a polder , or a dike construction . The type of material used for construction is hypothesized to affect the settlement of coastal organisms, although the precise mechanism has yet to be identified. A seawall works by reflecting incident wave energy back into the sea, thus reducing the energy available to cause erosion. Seawalls have two specific weaknesses. Wave reflection from

2640-612: The United Nations Environment Programme (UNEP) suggests that the tsunami of 26 December 2004 caused less damage in the areas where natural barriers were present, such as mangroves , coral reefs or coastal vegetation. A Japanese study of this tsunami in Sri Lanka used satellite imagery modelling to establish the parameters of coastal resistance as a function of different types of trees. Natural barriers, such as coral reefs and mangrove forests, prevent

3696-576: The Thames estuary occurred, prompting the construction of protection for further events in this flood-prone area. Since then, seawall design has become more complex and intricate in response to an improvement in materials, technology, and an understanding of how coastal processes operate. This section will outline some key case studies of seawalls in chronological order and describe how they have performed in response to tsunamis or ongoing natural processes and how effective they were in these situations. Analyzing

3784-510: The Vancouver Seawall is a prime example of how seawalls can simultaneously provide shoreline protection and a source of recreation which enhances human enjoyment of the coastal environment. It also illustrates that although shoreline erosion is a natural process, human activities, interactions with the coast, and poorly planned shoreline development projects can accelerate natural erosion rates. On December 26, 2004, towering waves of

In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of

4048-602: The area, and that some Iron Age finds also exist. During the Roman period , the area became part of the Roman communications network. It was connected by road to Canterbury and Watling Street and it became Portus Dubris , a fortified port. Dover has a partly preserved Roman lighthouse (the tallest surviving Roman structure in Britain) and the remains of a villa with preserved Roman wall paintings. Dover later figured in Domesday Book (1086). Forts were built above

4136-427: The artificial barrier which reinforces the effectiveness of seawalls. At least 43 percent of Japan's 29,751 km (18,486 mi) coastline is lined with concrete seawalls or other structures designed to protect the country against high waves, typhoons, or even tsunamis. During the 2011 Tōhoku earthquake and tsunami , the seawalls in most areas were overwhelmed. In Kamaishi , 4-metre (13 ft) waves surmounted

4224-608: The board members of the Dover Harbour Board are appointees of the Department for Transport . The port has its own private police force, the Port of Dover Police . The current port traffic volumes and urban population categorize Dover as a Large-Port Town. Recent archaeology indicates that Dover's history as a port and trading gateway dates back at least as far as the Stone and Bronze ages. Known as Dubris during

4312-526: The construction of a seawall, including the disruption of sediment movement and transport patterns. Combined with a high construction cost, this has led to increasing use of other soft engineering coastal management options such as beach replenishment . Seawalls are constructed from various materials, most commonly reinforced concrete , boulders, steel, or gabions . Other possible construction materials include vinyl, wood, aluminum, fiberglass composite, and biodegradable sandbags made of jute and coir . In

4400-618: The dismantling of the Dover Promenade Pier. The yard began to shrink after World War II and was closed in 1964 to make way for port redevelopment and a car ferry terminal. From 1930 until 1950 an aerial ropeway carried coal from Tilmanstone colliery, 7½ miles to the north. It emerged halfway up the Langdon cliffs directly above the Eastern harbour arm, through two portals which have been bricked up but can still be seen from

4488-579: The dockyards of Chatham and Portsmouth . In 1847 construction began on the Admiralty Pier. Envisaged as the Western Arm of the proposed haven, completion of the massive first stage in 1871 effectively stopped the silting of the harbour mouth as it cut off the drift of shingle from the direction of Folkestone . The Admiralty Pier was constructed using a foundation of Portland stone blocks surmounted by granite and durable Bramley Fall stone on

4576-454: The earthquake zone, as the tsunami washed over walls that were supposed to protect the plants. Arguably, the additional defense provided by the seawalls presented an extra margin of time for citizens to evacuate and also stopped some of the full force of energy which would have caused the wave to climb higher in the backs of coastal valleys. In contrast, the seawalls also acted in a negative way to trap water and delay its retreat. The failure of

4664-404: The extension of height and reinforcement of current seawalls which needs to occur for safety to be ensured in both situations. Sea level rise also will cause a higher risk of flooding and taller tsunamis. Seawalls, like all retaining walls , must relieve the buildup of water pressure . Water pressure buildup is caused when groundwater is not drained from behind the seawall. Groundwater against

4752-807: The ferry port. Coal was deposited in bunkers at the outer end of the Eastern harbour arm. The ropeway had 600 1-ton buckets that departed at intervals of 21 seconds and travelled at 4½ miles per hour. The system could thus transport 120 tons of coal per hour. The first two roll-on/roll-off ferry berths in the Eastern Docks were opened on 30 June 1953. The first ro-ro ferry, the appropriately modified British Railways' SS Dinard , departed for Boulogne on 3 July 1953. Today, there are seven active docks for Ro-Ro vessels to utilise at Dover, one deconstructed dock and one unused dock for high-speed Ro-Ro watercraft. In 1966 well over 600,000 accompanied vehicles travelled through Dover's Eastern Docks en route to France or Belgium. After rail services were extended to Dover in 1844,

4840-450: The first century BCE, Romans built a seawall or breakwater at Caesarea Maritima creating an artificial harbor (Sebastos Harbor). The construction used Pozzolana concrete which hardens in contact with seawater. Barges were constructed and filled with the concrete. They were floated into position and sunk. The resulting harbor/breakwater/seawall is still in existence today – more than 2000 years later. The oldest known coastal defense

4928-576: The focus of a £250 million port redevelopment project co-financed by the European Union. Conversion and restoration of the historic former Dover Marine rail terminus, and the opening of a second, larger, cruise terminal building in 1996, have supported a significant expansion in cruise ship traffic. Cruise Terminal 2 is able to accommodate ships as large as the Celebrity Silhouette at 319 metres (1,047 ft) in length overall ,

5016-402: The force of ongoing wave energy. Some understanding is needed of the coastal processes and morphodynamics specific to the seawall location. Seawalls can be very helpful; they can offer a more long-term solution than soft engineering options, additionally providing recreation opportunities and protection from extreme events as well as everyday erosion. Extreme natural events expose weaknesses in

The same element is present in the town's French name Douvres and the name of the river, Dour , which is also evident in other English towns such as Wendover . However, the modern Modern Welsh name Dofr

5808-407: The nearest point to the European mainland, Cap Gris Nez is 34 kilometres (21 mi) away across the Strait of Dover. The site of its original settlement lies in the valley of the River Dour , sheltering from the prevailing south-westerly winds. This has led to the silting up of the river mouth by the action of longshore drift . The town has been forced into making artificial breakwaters to keep

5896-401: The normal high-tide mark. The barrier was initially completed in 1735 and over the years, the French continued to fortify the wall, piling huge boulders along its 1.25 mi (2 km) coastline to stop erosion from the waves pounding the harbor. At its highest, the barrier running along the water's edge reaches about 27 ft (8.2 m) above sea level. The boulders, some weighing up to

The higher land on either side of the valley – the Western Heights and the eastern high point on which Dover Castle stands – has been adapted to perform the function of protection against invaders. The town has gradually extended up the river valley, encompassing several villages in doing so. Little growth

6424-657: The remains of another ship, the War Sepoy , were sunk alongside the Spanish Prince. Dover's Eastern Docks were used for ship breaking beginning during the First World War, when the Admiralty began dismantling ships there. The Stanlee Shipbreaking and Salvage Co. Ltd. took over the ship breaking operation commercially in 1920. Many of the ships broken up were naval vessels from the First World War. The company also handled machinery and general scrap, including

6512-596: The same time, this find also shows that trade routes across the Channel between England and France existed already in the Bronze Age , or even earlier. In 1992, the so-called Dover boat from the Bronze Age was discovered in six metres depth underwater. This is one of the oldest finds of a seaworthy boat. Using the radiocarbon method of investigation, the boat's construction was dated to approximately 1550 BC . First recorded in its Latinised form of Portus Dubris ,

6600-566: The seafloor. The Living Seawalls project, which was launched in Sydney , Australia, in 2018, aims to help many of the marine species in Sydney Harbour to flourish, thus enhancing its biodiversity , by modifying the design of its seawalls. It entails covering parts of the seawalls with specially-designed tiles that mimic natural microhabitats - with crevices and other features that more closely resemble natural rocks. In September 2021,

6688-481: The seawall began in 1917, and since then this pathway has become one of the most used features of the park by both locals and tourists and now extends 22 km in total. The construction of the seawall also provided employment for relief workers during the Great Depression and seamen from HMCS  Discovery on Deadman's Island who were facing punishment detail in the 1950s (Steele, 1985). Overall,

6776-474: The seawall – the world's largest, erected a few years ago in the city's harbor at a depth of 63 m (207 ft), a length of 2 km (1.2 mi) and a cost of $ 1.5 billion – and eventually submerged the city center. The risks of dependence on seawalls were most evident in the crisis at the Fukushima Dai-ichi and Fukushima Dai-ni nuclear power plants , both located along the coast close to

6864-749: The seaward facing exterior. Further construction from 1897 onwards established the Eastern Arm of the current harbour, the Southern Breakwater and a further extension of the Admiralty Pier. During the First World War , a former cargo ship, the Spanish Prince , was deliberately sunk by the Admiralty close to the entrance to Dover Harbour to prevent German U-Boats from firing torpedoes into the harbour. During World War II ,

6952-440: The single ship of SpeedFerries , SpeedOne , with up to five services daily to Boulogne-sur-Mer . The hoverport has now been demolished and redeveloped as a cargo handling facility. The harbour is divided into two main sections, the Eastern Docks and the Western Docks, about 1 kilometre (0.62 mi) apart. Cross channel ferry services to France operate from the seven twin-level ferry berths and associated departure buildings of

7040-411: The spread of tsunamis and the flow of coastal waters and mitigated the flood and surge of water. A cost-benefit approach is an effective way to determine whether a seawall is appropriate and whether the benefits are worth the expense. Besides controlling erosion, consideration must be given to the effects of hardening a shoreline on natural coastal ecosystems and human property or activities. A seawall

7128-583: The successes and shortcomings of seawalls during severe natural events allows their weaknesses to be exposed, and areas become visible for future improvement. The Vancouver Seawall is a stone seawall constructed around the perimeter of Stanley Park in Vancouver, British Columbia . The seawall was constructed initially as waves created by ships passing through the First Narrows eroding the area between Prospect Point and Brockton Point. Construction of

7216-471: The town. Route one goes from Dover to Canterbury. This route links with National Cycle Route 2 from Dover to St Austell, Regional route 16, and Regional route 17 in Dover. It passes three castles. Firstly from Dover on the steap incline past Dover Castle. Then South Foreland Lighthouse is visible from the route. Mostly traffic-free along the east coast from Kingsdown to Deal, passing Walmer Castle and Deal Castle . Follows toll road (free to cyclists) through

7304-511: The use of sluices and the development of an enclosed pool of water known as the Great Pent, by means of which the harbour could be periodically scoured. The Great Pent was formed by the construction of a cross wall across the existing natural shingle lagoon at the mouth of the River Dour: the work was largely undertaken by labourers from Romney Marsh , using skills honed in the construction of seawalls . The project has been described as "one of

7392-549: The wall may result in hydrodynamic scour and subsequent lowering of the sand level of the fronting beach. Seawalls may also accelerate the erosion of adjacent, unprotected coastal areas by affecting the littoral drift process. Different designs of man-made tsunami barriers include building reefs and forests to above-ground and submerged seawalls. Starting just weeks after the disaster, in January 2005, India began planting Casuarina and coconut saplings on its coast as

7480-605: The world's largest seawall, which cost $ 1.5 billion to construct, shows that building stronger seawalls to protect larger areas would have been even less cost-effective. In the case of the ongoing crisis at the nuclear power plants, higher and stronger seawalls should have been built if power plants were to be built at that site. Fundamentally, the devastation in coastal areas and a final death toll predicted to exceed 10,000 could push Japan to redesign its seawalls or consider more effective alternative methods of coastal protection for extreme events. Such hardened coastlines can also provide

7568-763: Was designed to prevent erosion from everyday waves only, and when a storm in 1976 carved out ten meters behind the existing seawall, the whole structure was destroyed. The addition of seawalls near marine ecosystems can lead to increased shadowing effects in the waters surrounding the seawall. Shadowing reduces the light and visibility within the water, which may disrupt the distribution as well as foraging capabilities of certain species. The sediment surrounding seawalls tends to have less favorable physical properties (Higher calcification levels, less structural organization of crystalline structure, low silicon content, and less macroscale roughness) when compared to natural shorelines, which can present issues for species that reside on

7656-535: Was electrified under British Railways in 1959 as part of Stage 1 of Kent Coast Electrification, under the BR 1955 Modernisation Plan . The line up to Ramsgate, via Deal, was subsequently electrified under stage two of Kent Coast electrification in January 1961. The line from Folkestone into Priory was electrified in June 1961. A tram system operated in the town from 1897 to 1936. Dover has two long distance footpaths :

7744-681: Was originally operated by ferry operator Norfolkline . This company was later acquired by the pan European operator DFDS Seaways in July 2010. The crossing time is approximately two hours. The location of Dunkirk is also more convenient for those travelling by road transport on to countries in Northern Europe including Belgium , the Netherlands , Germany and further afield. Stagecoach in East Kent provide local bus services. Dover
