An artificial island or man-made island is an island that has been constructed by humans rather than formed through natural processes. Other definitions may suggest that artificial islands are lands with the characteristics of human intervention in their formation process, while others argue that artificial islands are created by expanding existing islets , constructing on existing reefs , or amalgamating several islets together. Although constructing artificial islands is not a modern phenomenon, there is no definite legal definition of it. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure to those that support entire communities and cities. Archaeologists argue that such islands were created as far back as the Neolithic era . Early artificial islands included floating structures in still waters or wooden or megalithic structures erected in shallow waters (e.g. crannógs and Nan Madol discussed below).
86-556: The Palm Islands consist of three artificial archipelagos : Palm Jumeirah , Dubai Islands (formerly known as Palm Deira or Deira Islands), and Palm Jebel Ali , on the coast of Dubai , United Arab Emirates . The Palm Islands were constructed around the same time as The World Islands . Nakheel Properties is the Palm Islands real estate developer. The creation of the islands began in 2001 and ended around 2006/2007. These islands have significantly impacted ocean sediment and wildlife in
172-399: A clear distinction between land masses eligible for expansion into new island groups and those that do not qualify. According to this legal framework, low-tide elevations are considered part of the seabed and do not generate a territorial sea, EEZ, or continental shelf. However, they serve as a reference point for measuring the entitlements of nearby rocks or islands. Rocks, unlike islands, lack

Beaches dissipate wave energy on the foreshore and provide a measure of protection to the adjoining land. The stability of the foreshore, or its resistance to lowering. Once stable, the foreshore should widen and become more effective at dissipating the wave energy, so that fewer and less powerful waves reach beyond it. The provision of updrift material coming onto

During the isolationist era, Dutch people were generally banned from Nagasaki and Japanese from Dejima. Similarly, Ellis Island , in Upper New York Bay beside New York City , a former tiny islet greatly expanded by land reclamation , served as an isolated immigration center for
516-712: A definition of hybrid warfare that suggests it is targeted at populations. Additionally, China's objective is not to destabilise other states, but rather to enhance its national security by gaining control over regional waters. Furthermore, China is not aiming to seize control from another power, but rather seeks to establish a dominant security and political position in the region. It is worth noting that China employs unarmed or lightly armed vessels deliberately, as they are unlikely to resort to deadly force. However, others argue that China's greyzone tactics can be classified as hybrid warfare. Some viewpoints contend that China's establishment of military bases on artificial islands serves as
602-469: A horrific case of coastal erosion is due to an increase in the frequency and the intensity of storms it experienced. These natural events had destroyed the Hampton Pier, Hernecliffe Gardens, a set of villas, several roads, and many other structures that once lay on Hampton-On-Sea. After this destruction, in 1899 they started building a sea wall to protect the rest of the remaining land and buildings. However,
688-404: A length of about 11.5 km, the base of these breakwaters and the island itself were constantly monitored during the construction process with the help of deep-sea divers. The divers checked the alignment and placement of the rocks beneath the surface to ensure their stability. The shape of the island was monitored using the global positioning system. The sand on top of the island was sprayed by
774-483: A means to assert their territorial claims through the use of force. This approach is referred to as the Cabbage strategy, wherein a contested area is encircled by multiple layers of security to deny access to rival nations, ultimately solidifying their claim. While there is no consensus on China's motives behind the creation of artificial islands, it is widely acknowledged that China aims to bolster its power and influence in

The area is said to be the fastest-eroding shore of the United States' West Coast. Measures were finally taken to slow the erosion, with substantial slowing of the process noted in 2018. Fort Ricasoli , a historic 17th century fortress in Malta is being threatened by coastal erosion, as it
946-576: A solution that keeps in mind environmental justice . Typically, there has been low public support for "retreating". However, if a community does decide to relocate their buildings along the coast it is common that they will then turn the land into public open space or transfer it into land trusts in order to protect it. These relocation practices are very cost-efficient, can buffer storm surges, safeguard coastal homes and businesses, lower carbon and other pollutants, create nursery habitats for important fish species, restore open space and wildlife, and bring back

#17328378767951032-410: A technique called rainbowing . The whole island was planned to have no stagnant water between the island and the breakwaters. To achieve this, small structural modifications were made to the breakwaters surrounding the island, allowing the seawater to move through the breakers without causing any damage to the island. To prevent erosion of the sand from the island, maintenance systems spray material along
1118-552: A temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion , impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels , bridges , columns , and pillars . Over time
1204-697: A whole new range of solutions to coastal erosion, not just structural solutions. Solutions that have potential include native vegetation, wetland protection and restoration, and relocation or removal of structures and debris. The solutions to coastal erosion that include vegetation are called "living shorelines". Living shorelines use plants and other natural elements. Living shorelines are found to be more resilient against storms, improve water quality, increase biodiversity, and provide fishery habitats. Marshes and oyster reefs are examples of vegetation that can be used for living shorelines; they act as natural barriers to waves. Fifteen feet of marsh can absorb fifty percent of

It consists of a series of 15 large artificial islands covering an area of about 5 km2 (54,000,000 sq ft) and has six atolls, five fish-shaped islands, two crescent-shaped islands, and two more small islands related to the Marina area. In 1969, the Flevopolder in the Netherlands was finished, as part of the Zuiderzee Works . It has a total land surface of 970 km , which makes it by far
1634-502: Is due to waves causing erosion of the primarily sedimentary material on which the buildings foundations sit. Dunwich , the capital of the English medieval wool trade, disappeared over the period of a few centuries due to redistribution of sediment by waves. Human interference can also increase coastal erosion: Hallsands in Devon , England, was a coastal village washed away over the course of
1720-426: Is estimated the average life span of a seawall is 50–100 years and the average for a groyne is 30–40 years. Because of their relative permanence, it is assumed that these structures can be a final solution to erosion. Seawalls can also deprive public access to the beach and drastically alter the natural state of the beach. Groynes also drastically alter the natural state of the beach. Some claim that groynes could reduce
1806-583: Is suffering from this problem as well. Hampton-on-Sea is located in Kent, England. It was at one time very popular for its oyster fishing and was very reliant on the sea. Hampton-on-Sea has undergone the effects of coastal erosion since before the 1800s. Hampton-on-Sea's coastal erosion worsened with the increase in global warming and climate change. Global warming is causing a rise in sea level, more intense and frequent storms, and an increase in ocean temperature and precipitation levels. Another reason Hampton-on-Sea had such

Some argue, that China's greyzone tactics mainly aim to improve its geopolitical position in a peaceful manner. In contrast to the greyzone tactics used by Russia in Crimea in 2014, China's approach differs significantly. One supporting argument is that the majority of the activities occur in uninhabited areas at sea, which contradicts
2064-544: Is understood as a form of conflict that combines conventional and irregular tactics. Hybrid warfare may also be defined as a multifaceted strategy aimed at destabilising a functioning state and dividing its society. This comprehensive definition portrays hybrid strategy as a versatile and complex approach utilising a combination of conventional and unconventional means, overt and covert activities, involving military, paramilitary, irregular, and civilian actors across different domains of power. The ultimate objective of hybrid warfare
2150-469: Is worth mentioning that artificial islands may include stationary oil rigs. Coastal states are permitted to undertake reclamation within designated areas as long as they fulfil their obligation to inform other countries and respect their rights, as outlined by UNCLOS rules. However, any artificial islands created through this process are restricted to maintaining a 500-meter safety zone around them and must not obstruct international navigation. Hybrid warfare

However, beyond this 12 nautical mile limit, the country must consider whether its actions conform to the rights and jurisdictions recognised by UNCLOS. Reclamation activities conducted between 12 and 200 nautical miles are considered part of the process of establishing and utilising artificial islands, installations, and structures, governed by specific provisions within UNCLOS.

Additional data was collected with technological improvements, including remote video monitoring of Dubai beaches, sediment sampling and analysis, near-shore directional wave and current recordings, and intensive measurement exercises at selected locations using Acoustic Doppler Current Profiler (ADCP) equipment. Because of this, they can constantly monitor the continuously changing environmental conditions along
2924-671: The Philippines and China have been reported to have constructed artificial islands in the South China Sea, primarily to assert territorial claims over the disputed waters. Similarly, Russia has allegedly done so in the Arctic, both for strategic and military purposes. These reports are subject to ongoing political and diplomatic debates. The island-building activities of China have been the subject of close examination by experts, who suggest that they are driven by strategic objectives. The issue at
3010-575: The South China Sea. China began building islands in the 1980s, initially creating a series of minor military garrisons. However, the reason why China faces criticism is because some of the reclaimed islands fall within the EEZs of other countries, which raises concerns about China's compliance with UNCLOS. Vietnam has also made a historical claim, pointing to its rule over the islands in the 17th century. The Philippines argues for its rights based on geographical proximity. Meanwhile, Malaysia and Brunei claim parts of

Corrosion or solution/chemical weathering occurs when the sea's pH (anything below pH 7.0) corrodes rocks on a cliff face. Limestone cliff faces, which have a moderately high pH, are particularly affected in this way. Wave action also increases the rate of reaction by removing the reacted material. The ability of waves to cause erosion of

Solution is the process in which acishutds contained in sea water will dissolve some types of rock such as chalk or limestone. Abrasion , also known as corrasion , occurs when waves break on cliff faces and slowly erode it. As the sea pounds cliff faces it also uses the scree from other wave actions to batter and break off pieces of rock from higher up
3354-443: The coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. Also erosion commonly happens in areas where there are strong winds, loose sand , and soft rocks. The blowing of millions of sharp sand grains creates a sandblasting effect. This effect helps to erode, smooth and polish rocks. The definition of erosion is grinding and wearing away of rock surfaces through

At first, the project—which was supposed to be a part of the Palm Islands—was known as Palm Deira. It was intended to be the biggest palm of the three, roughly eight times as big as the Palm Jumeirah. Dubai built the Palm Tree Islands to increase the coastline for tourists.

To properly manage their shorelines and effects, Dubai relies on its coastal monitoring program. Established in 1997, the Dubai Coastal Monitoring program began studying the baseline bathymetric (measurement of the depth of water in oceans or seas) and topographic survey of

This was done to hold the island's base together and to make a strong foundation for further construction. The construction of the Palm Islands along the coast of Dubai has had a significant impact on the surrounding environment, resulting in changes to area wildlife (especially aquatic life), coastal erosion , alongshore sediment transport, and wave patterns. The origin of most of

The unrecognised micronation known as the Principality of Sealand (often shorted to simply "Sealand") is entirely on a single artificial island. Over time, after World War II , several countries have been reported to have built artificial islands for strategic and military purposes. For instance,

One of the world's largest artificial islands, René-Levasseur Island , was formed by the flooding of two adjacent reservoirs. Technological advancements have made it feasible to build artificial islands in waters as deep as 75 meters. The size of the waves and

At that time, China recovered islands in the name of the Cairo Declaration and the Potsdam Proclamation , and there was no reaction from Vietnam or any other state against it. In 1947, China drafted the eleven-dash line (also referred to as the nine-dash line ) to outline the geographical scope of its authority over
4042-411: The cracks can grow, sometimes forming a cave . The splinters fall to the sea bed where they are subjected to further wave action. Attrition occurs when waves cause loose pieces of rock debris ( scree ) to collide with each other, grinding and chipping each other, progressively becoming smaller, smoother and rounder. Scree also collides with the base of the cliff face, chipping small pieces of rock from

Before-and-after comparisons can be made using data gathered by manual surveying, laser altimeter , or a GPS unit mounted on an ATV. Remote sensing data such as Landsat scenes can be used for large scale and multi year assessments of coastal erosion. Moreover, geostatistical models can be applied to quantify erosion effects and
4300-443: The effects of erosion. These options, including Sandbag and beach nourishment , are not intended to be long-term solutions or permanent solutions. Another method, beach scraping or beach bulldozing allows for the creation of an artificial dune in front of a building or as means of preserving a building foundation. However, there is a U.S. federal moratorium on beach bulldozing during turtle nesting season, 1 May – 15 November. One of

The natural processes of both absolute and relative sea level rise and erosion are considered in rebuilding. Depending on factors such as the severity of the erosion, as well as the natural landscape of the property, relocation could simply mean moving inland by a short distance or relocation can be to completely remove improvements from an area. A coproduction approach combined with managed retreat has been proposed as

#17328378767954472-463: The environmental damage stems from disturbed sediment from the construction of the Palm Island. The sediment decreased the amount of sunlight filtering down to the sea vegetation and injured the surrounding marine fauna. Environmental disturbances caused by changes in sediment and coastal erosion have attracted the attention of environmental groups such as Greenpeace , who criticized the Palm Islands for
4558-530: The eroded sands that attract visitors to Florida and help support its multibillion-dollar tourism industries. There are three common forms of coastal erosion control methods. These three include: soft-erosion controls, hard-erosion controls, and relocation. Hard-erosion control methods provide a more permanent solution than soft-erosion control methods. Seawalls and groynes serve as semi-permanent infrastructure. These structures are not immune from normal wear-and-tear and will have to be refurbished or rebuilt. It

The adjacent bathymetry , or configuration of the seafloor, controls the wave energy arriving at the coast, and can have an important influence on the rate of cliff erosion. Shoals and bars offer protection from wave erosion by causing storm waves to break and dissipate their energy before reaching the shore. Given the dynamic nature of

Over the years beach nourishment has become a very controversial shore protection measure: It has the potential to negatively impact several of the natural resources. Some large issues with these beach nourishment projects are that they must follow a wide range of complex laws and regulations, as well as
4816-688: The heart of the matter revolves around China's claim that its historical entitlement justifies its actions in the area. This is opposed by the legal argument supported by the United Nations Convention on the Law of the Sea (UNCLOS). It is noteworthy that UNCLOS serves as the primary legal framework that governs the use and control of maritime zones. This convention establishes regulations on how coastal states can exercise their sovereignty over territorial waters, contiguous zones, exclusive economic zones ( EEZs ), and
4902-400: The high expenses it takes to complete these projects. Just because sand is added to a beach does not mean it will stay there. Some communities will bring in large volumes of sand repeatedly only for it to be washed away with the next big storm. Despite these factors, beach nourishment is still used often in many communities. Lately, the U.S. Army Corps of Engineers emphasized the need to consider

The increased amount of sand, sediment, and fine particles creates turbid conditions, blocking necessary UV rays from reaching coral reefs, creating coral turbidity (where more organic material is taken in by coral) and increasing bacterial activity (more harmful bacteria are introduced into coral). The construction of artificial islands also decreases
5504-487: The mechanical action of other rock or sand particles. According to the IPCC, sea level rise caused by climate change will increase coastal erosion worldwide, significantly changing the coasts and low-lying coastal areas. Hydraulic action occurs when waves striking a cliff face compress air in cracks on the cliff face. This exerts pressure on the surrounding rock, and can progressively splinter and remove pieces. Over time,
5590-416: The most common methods of soft erosion control is beach nourishment projects. These projects involve dredging sand and moving it to the beaches as a means of reestablishing the sand lost due to erosion. In some situations, beach nourishment is not a suitable measure to take for erosion control, such as in areas with sand sinks or frequent and large storms.

Nevertheless, China has repeatedly challenged this principle by constructing artificial islands, imposing restrictions on navigation, and militarising the area. The legal implications surrounding China's island construction efforts present complex challenges. A key issue revolves around determining the classification of land masses as either rocks or seabed, which holds significant importance in these disputed cases. Maritime law establishes

Therefore, China's construction of artificial islands raises questions about whether they can legitimately claim an EEZ around those islands. UNCLOS also enshrines the freedom of navigation and overflight in the EEZ of coastal states, which implies that all countries have

These events cause many land investors to back out. Eventually, Hampton-on-Sea had to be abandoned because the erosion overtook so much of the land. By 1916 Hampton-on-Sea had been completely abandoned. By the 1920s only a couple of structures still stood. It
