Bonaire
–
Bonaire is an island in the Leeward Antilles in the Caribbean Sea. Together with Aruba and Curaçao, it forms the group known as the ABC islands, unlike much of the Caribbean region, the ABCs lie outside the hurricane belt. The islands have a climate, which helps tourism, as visitors to the islands can reliably expect warm. Bonaire is a destination for SCUBA divers, and it is also well known for easy access to its various reefs from the shore. The island has a permanent population of 18,905 and an area of 294 km2, Bonaire was part of the Netherlands Antilles until the countrys dissolution in 2010, when the island became a special municipality within the country of the Netherlands. It is one of the three BES islands in the Caribbean, the other two BES islands are Sint Eustatius and Saba, the name Bonaire is thought to have originally come from the Caquetio word Bonay, a name that meant low country. The early Spanish and Dutch modified its spelling to Bojnaj and also Bonaire, the French influence, while present at various times, was never strong enough to make the assumption that the name means good air. Bonaires earliest known inhabitants were the Caquetio Indians, a branch of the Arawak who came by canoe from Venezuela in about 1000 AD, archeological remains of Caquetio culture have been found at certain sites northeast of Kralendijk and near Lac Bay. Caquetio rock paintings and petroglyphs have been preserved in caves at Spelonk, Onima, Ceru Pungi, the Caquetios were apparently a very tall people, for the Spanish name for the ABC Islands was las Islas de los Gigantes or the islands of the giants. In 1499, Alonso de Ojeda arrived in Curaçao and an island that was almost certainly Bonaire. Ojeda was accompanied by Amerigo Vespucci and Juan de la Cosa, de La Cosas Mappa Mundi of 1500 shows Bonaire and calls it Isla do Palo Brasil or Island of Brazilwood. In 1526, Juan de Ampies was appointed Spanish commander of the ABC Islands and he brought back some of the original Caquetio Indian inhabitants to Bonaire and Curaçao. Ampies also imported domesticated animals from Spain, including cows, donkeys, goats, horses, pigs, the Spaniards thought that Bonaire could be used as a cattle plantation worked by natives. The cattle were raised for hides rather than meat, the Spanish inhabitants lived mostly in the inland town of Rincon which was safe from pirate attack. The Dutch West India Company was founded in 1621, starting in 1623, ships of the West India Company called at Bonaire to obtain meat, water, and wood. The Dutch also abandoned some Spanish and Portuguese prisoners there, the Dutch and the Spanish fought from 1568 to 1648 in what is now known as the Eighty Years War. In 1633, the Dutch—having lost the island of St. Maarten to the Spanish—retaliated by attacking Curaçao, Bonaire, Bonaire was conquered in March 1636. The Dutch built Fort Oranje in 1639, while Curaçao emerged as a center of the slave trade, Bonaire became a plantation of the Dutch West India Company

Saba
–
Saba is a Caribbean island and the smallest special municipality of the Netherlands. It consists largely of the active volcano Mount Scenery, at 887 metres the highest point of the entire Netherlands. Saba has an area of 13 square kilometres. As of January 2013, the population was 1,991 inhabitants and its towns and major settlements are The Bottom, Windwardside, Hells Gate and St. Johns. The origin of the name Saba comes from the Arabic word Sabha, like many Caribbean islands, Saba is highly dependent on fossil fuels imports, which leaves it vulnerable to global oil price fluctuations that directly impact the cost of electricity. This new energy policy is defined by the development plan 2014–2020’. Intermediate targets are 20% renewable electricity by 2017 and 40% by 2020, christopher Columbus is said to have sighted the island on 13 November 1493. He did not land, being deterred by the islands rocky shores. In 1632, a group of shipwrecked Englishmen landed upon Saba and they stated they found the island uninhabited when they were rescued, however, clear evidence has been found indicating that Caribs and Arawak Native Nations have lived on the island. In 1635, a stray Frenchman claimed Saba for Louis XIII of France, in the latter 1630s, the Dutch Governor of the neighboring island of Sint Eustatius sent several Dutch families over to colonize the island for the Dutch West India Company. These Dutch family names included Hassell, Heyliger, Leverock, Zagers, the Netherlands have been in continuous possession of Saba since 1816, after numerous flag changes during the previous centuries. By 2016 the island had been French for 12 years, English for 18 years, in the 17th and 18th centuries Sabas major industries were sugar, indigo and rum produced on plantations owned by Dutchmen living on St Eustatius, and later fishing, particularly lobster fishing. In the 17th century Saba was believed to be a hideout for Jamaican pirates. England also deported its undesirable people to live in the Caribbean colonies, and some of them also became pirates, the island of Saba is forbidding and steep, a natural fortress, and so the island became a private sanctuary for the families of smugglers and pirates. The most notable native Saban pirate was Hiram Beakes, who famously quipped, during this period of time, with most of the islands men gone out to sea, the island became known as The Isle of Women. The remains of the settlements of 1630–40 can be found on the west side at Tent Bay and these settlements were destroyed by a landslide in the 17th century. A status referendum was held in Saba on 5 November 2004,86. 05% of the population voted for closer links to the Netherlands. Saba consists largely of the active volcano Mount Scenery

Sint Eustatius
–
Sint Eustatius, also known affectionately to the locals as Statia, is part of the Caribbean Netherlands, i. e. it is a Caribbean island and a special municipality of the Netherlands. The island lies in the northern Leeward Islands portion of the West Indies, Sint Eustatius is immediately to the northwest of Saint Kitts, and to the southeast of Saba. The island has an area of 21 square kilometres, in the 2001 census, the population was recorded as 3,543 inhabitants, with a population density of 169 inhabitants per square kilometre. As of 2015, the population was estimated at 3,877. The official language is Dutch, but English is the language of life on the island. A local English-based creole is spoken informally. Travellers to the island by air arrive through F. D, formerly part of the Netherlands Antilles, Sint Eustatius became a special municipality within The Netherlands on 10 October 2010. The name of the island, “Sint Eustatius”, is the Dutch name for Saint Eustace, the island was seen by Christopher Columbus in 1493 and claimed by many different nations. From the first settlement, in the 17th century until the early 19th century, in 1636, the chamber of Zeeland of the Dutch West India Company took possession of the island that was then reported to be uninhabited. As of 1678, the islands of St. Eustatius, Sint Maarten and Saba fell under command of the Dutch West India Company. At the time, the island was of importance for cultivation of tobacco. Its economy developed by ignoring the monopolistic trade restrictions of the British, French, St. Eustatiuss economy, under the Dutch, flourished. The island was known as The Golden Rock, edmund Burke said of the island in 1781, It has no produce, no fortifications for its defense, nor martial spirit nor military regulations. The universality of its use, the neutrality of its nature was its security and its proprietors had, in the spirit of commerce, made it an emporium for all the world. Its wealth was prodigious, arising from its industry and the nature of its commerce, the island sold arms and ammunition to anyone willing to pay. It was one of the few places from which the young United States could obtain military stores, the good relationship between St. Eustatius and the United States resulted in the noted First Salute. On November 16,1776, Captain Isaiah Robinson of the 14-gun American brig Andrew Doria, Robinson announced his arrival by firing a thirteen gun salute, one gun for each of the thirteen American colonies in rebellion against Britain. Governor Johannes de Graaff replied with a gun salute from the cannons of Fort Oranje

Aruba
–
It measures 32 kilometres long from its northwestern to its southeastern end and 10 kilometres across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands, collectively, Aruba and the other Dutch islands in the Caribbean are often called the Dutch Caribbean. Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, the citizens of these countries all share a single nationality, Dutch. Aruba has no subdivisions, but, for census purposes, is divided into eight regions. Unlike much of the Caribbean region, Aruba has a dry climate and this climate has helped tourism as visitors to the island can reliably expect warm, sunny weather. It has an area of 179 km2 and is densely populated. Arubas first inhabitants are thought to have been Caquetío Amerindians from the Arawak tribe, fragments of the earliest known Indian settlements date back to 1000 AD. As sea currents made travel to other Caribbean islands difficult. Europeans first learned of Aruba following the explorations for Spain by Amerigo Vespucci, both described Aruba as an island of giants, remarking on the comparatively large stature of the native Caquetíos compared to Europeans. Gold was not discovered on Aruba for another 300 years, Vespucci returned to Spain with stocks of cotton and brazilwood from the island and described houses built into the ocean. Vespucci and Ojedas tales spurred interest in Aruba, and Spaniards soon colonized the island, because it had low rainfall, Aruba was not considered profitable for the plantation system and the economics of the slave trade. Aruba was colonized by Spain for over a century, simas, the Cacique, or chief, in Aruba, welcomed the first Catholic priests in Aruba, who gave him a wooden cross as a gift. In 1508, the Spanish Crown appointed Alonso de Ojeda as its first Governor of Aruba, Arawaks spoke the broken Spanish which their ancestors had learned on Hispaniola. Another governor appointed by Spain was Juan Martínez de Ampiés, a cédula real decreed in November 1525 gave Ampiés, factor of Española, the right to repopulate Aruba. In 1528, Ampiés was replaced by a representative of the House of Welser, the Dutch statutes have applied to Aruba since 1629. The Netherlands acquired Aruba in 1636, since 1636, Aruba has been under Dutch administration, initially governed by Peter Stuyvesant, later appointed to New Amsterdam. Stuyvesant was on a mission in Aruba in November and December 1642. The island was included under the Dutch West India Company administration, as New Netherland and Curaçao, in 1667 the Dutch administration appointed an Irishman as Commandeur in Aruba

Sint Maarten
–
Sint Maarten is an island country in the Caribbean. It is a constituent country of the Kingdom of the Netherlands, before 10 October 2010, Sint Maarten was known as the Island Territory of Sint Maarten, and was one of five island territories that constituted the Netherlands Antilles. However, though he claimed it as a Spanish territory, Columbus never landed there, the French and Dutch, on the other hand, both coveted the island. While the French wanted to colonize the islands between Trinidad and Bermuda, the Dutch found San Martín a convenient halfway point between their colonies in New Amsterdam and Brazil. With few people inhabiting the island, the Dutch easily founded a settlement there in 1631, jan Claeszen Van Campen became its first governor, and soon thereafter the Dutch West India Company began its salt mining operations. French and British settlements sprang up on the island as well, taking note of these successful colonies and wanting to maintain their control of the salt trade, the Spanish now found St. Martin much more appealing. The Eighty Years War which had been raging between Spain and the Netherlands provided further incentive to attack, Spanish forces captured Saint Martin from the Dutch in 1633, seizing control and driving most or all of the colonists off the island. At Point Blanche, they built what is now Old Spanish Fort to secure the territory, although the Dutch retaliated in several attempts to win back St. Martin, they failed. Fifteen years after the Spanish conquered the island, the Eighty Years War ended, since they no longer needed a base in the Caribbean and St. Martin barely turned a profit, the Spanish lost their inclination to continue defending it. In 1648, they deserted the island, with St. Martin free again, both the Dutch and the French jumped at the chance to re-establish their settlements. Dutch colonists came from St. Eustatius, while the French came from St. Kitts, after some initial conflict, both sides realized that neither would yield easily. Preferring to avoid a war, they signed the Treaty of Concordia in 1648. During the treatys negotiation, the French had a fleet of ships off shore. In spite of the treaty, relations between the two sides were not always cordial, between 1648 and 1816, conflicts changed the border sixteen times. The entire island came under effective French control from 1795 when Netherlands became a state under the French Empire until 1815. In the end, the French came out ahead with 53 km2 against 34 km2 on the Dutch side, with the new cultivation of cotton, tobacco, and sugar, the French and the Dutch imported a massive number of slaves to work on the plantations. The slave population grew larger than that of the land owners. Subjected to cruel treatment, slaves staged rebellions, and their overwhelming numbers made it impossible to ignore their concerns, in 1848, the French abolished slavery in their colonies including the French side of St. Martin

Sea level
–
Mean sea level is an average level of the surface of one or more of Earths oceans from which heights such as elevations may be measured. A common and relatively straightforward mean sea-level standard is the midpoint between a low and mean high tide at a particular location. Sea levels can be affected by factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, the term above sea level generally refers to above mean sea level. Precise determination of a sea level is a difficult problem because of the many factors that affect sea level. Sea level varies quite a lot on several scales of time and this is because the sea is in constant motion, affected by the tides, wind, atmospheric pressure, local gravitational differences, temperature, salinity and so forth. The easiest way this may be calculated is by selecting a location and calculating the mean sea level at that point, for example, a period of 19 years of hourly level observations may be averaged and used to determine the mean sea level at some measurement point. One measures the values of MSL in respect to the land, hence a change in MSL can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates. In the UK, the Ordnance Datum is the sea level measured at Newlyn in Cornwall between 1915 and 1921. Prior to 1921, the datum was MSL at the Victoria Dock, in Hong Kong, mPD is a surveying term meaning metres above Principal Datum and refers to height of 1. 230m below the average sea level. In France, the Marégraphe in Marseilles measures continuously the sea level since 1883 and it is used for a part of continental Europe and main part of Africa as official sea level. Elsewhere in Europe vertical elevation references are made to the Amsterdam Peil elevation, satellite altimeters have been making precise measurements of sea level since the launch of TOPEX/Poseidon in 1992. A joint mission of NASA and CNES, TOPEX/Poseidon was followed by Jason-1 in 2001, height above mean sea level is the elevation or altitude of an object, relative to the average sea level datum. It is also used in aviation, where some heights are recorded and reported with respect to sea level, and in the atmospheric sciences. An alternative is to base height measurements on an ellipsoid of the entire Earth, in aviation, the ellipsoid known as World Geodetic System 84 is increasingly used to define heights, however, differences up to 100 metres exist between this ellipsoid height and mean tidal height. The alternative is to use a vertical datum such as NAVD88. When referring to geographic features such as mountains on a topographic map, the elevation of a mountain denotes the highest point or summit and is typically illustrated as a small circle on a topographic map with the AMSL height shown in metres, feet or both. In the rare case that a location is below sea level, for one such case, see Amsterdam Airport Schiphol

Dike (construction)
–
A levee, dike, dyke, embankment, floodbank or stopbank is an elongated naturally occurring ridge or artificially constructed fill or wall, which regulates water levels. It is usually earthen and often parallel to the course of a river in its floodplain or along low-lying coastlines, the word levee, from the French word levée, is used in American English. It originated in New Orleans a few years after the founding in 1718 and was later adopted by English speakers. The name derives from the trait of the ridges being raised higher than both the channel and the surrounding floodplains. The modern word dike or dyke most likely derives from the Dutch word dijk, the 126 kilometres long Westfriese Omringdijk was completed by 1250, and was formed by connecting existing older dikes. The Roman chronicler Tacitus even mentions that the rebellious Batavi pierced dikes to flood their land, the word dijk originally indicated both the trench and the bank. It is closely related to the English verb to dig, in Anglo-Saxon, the word dic already existed and was pronounced as dick in northern England and as ditch in the south. Similar to Dutch, the English origins of the lie in digging a trench. This practice has meant that the name may be given to either the excavation or the bank, thus Offas Dyke is a combined structure and Car Dyke is a trench though it once had raised banks as well. In the midlands and north of England, and in the United States, a dike is what a ditch is in the south, a property boundary marker or small drainage channel. Where it carries a stream, it may be called a dike as in Rippingale Running Dike. The Weir Dike is a dike in Bourne North Fen, near Twenty and alongside the River Glen. In the Norfolk and Suffolk Broads, a dyke may be a ditch or a narrow artificial channel off a river or broad for access or mooring, some longer dykes being named. In parts of Britain, particularly Scotland, a dyke may be a field wall, Levees can be mainly found along the sea, where dunes are not strong enough, along rivers for protection against high-floods, along lakes or along polders. Furthermore, levees have been built for the purpose of empoldering, the latter can be a controlled inundation by the military or a measure to prevent inundation of a larger area surrounded by levees. Levees have also built as field boundaries and as military defences. More on this type of levee can be found in the article on dry-stone walls, Levees can be permanent earthworks or emergency constructions built hastily in a flood emergency. When such a bank is added on top of an existing levee it is known as a cradge

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

River delta
–
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, River deltas are ecologically important as they provide coastline defense, are home to many species, and can impact drinking water supply. The tidal currents also cannot be too strong, as sediment would wash out into the body faster than the river deposits it. Of course, the river must carry enough sediment to layer into deltas over time, the rivers velocity decreases rapidly, causing it to deposit the majority, if not all, of its load. This alluvium builds up to form the river delta, when the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, as a result, sediment drops out of the flow and deposits. Over time, this single channel builds a deltaic lobe, pushing its mouth into the standing water, as the deltaic lobe advances, the gradient of the river channel becomes lower because the river channel is longer but has the same change in elevation. As the slope of the channel decreases, it becomes unstable for two reasons. First, gravity makes the flow in the most direct course down slope. If the river breaches its natural levees, it out onto a new course with a shorter route to the ocean. Second, as its slope gets lower, the amount of stress on the bed decreases, which results in deposition of sediment within the channel. This makes it easier for the river to breach its levees, often when the channel does this, some of its flow remains in the abandoned channel. When these channel-switching events occur, a mature delta develops a distributary network, another way these distributary networks form is from deposition of mouth bars. When this mid-channel bar is deposited at the mouth of a river and this results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta, in both of these cases, depositional processes force redistribution of deposition from areas of high deposition to areas of low deposition. This results in the smoothing of the shape of the delta as the channels move across its surface. Because the sediment is laid down in fashion, the shape of these deltas approximates a fan. The more often the flow changes course, the shape develops as closer to an ideal fan, the Mississippi and Ural River deltas, with their birds-feet, are examples of rivers that do not avulse often enough to form a symmetrical fan shape
10.
Seawall
–
A seawall is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a sea wall is to protect areas of habitation, conservation and leisure activities from the action of tides, waves. As a seawall is a feature it will conflict with the dynamic nature of the coast. The coast is generally a high-energy, dynamic environment with spatial variations over a range of timescales. The coast is exposed to erosion by rivers and winds as well as the sea, because of these persistent natural forces, sea walls need to be maintained to maintain their effectiveness. Sea walls are hard engineering shore-based structures which protect the coast from erosion, but various environmental problems and issues may arise from the construction of a sea wall, including disrupting sediment movement and transport patterns. Combined with a construction cost, this has led to an increasing use of other soft engineering coastal management options such as beach replenishment. Sea walls may be constructed from various materials, most commonly reinforced concrete, boulders, steel, other possible construction materials are, vinyl, wood, aluminium, fibreglass composite, and large biodegrable sandbags made of jute and coir. In the UK, sea wall also refers to a bank used to create a polder. A seawall works by reflecting incident wave energy back into the sea, sea walls have two specific weaknesses. First, wave reflection from the wall may result in scour, second, sea walls may accelerate erosion of adjacent, unprotected coastal areas because they affect the littoral drift process. Different designs of man-made tsunami barriers include building reefs and forests to above-ground, in 2005, India began planting Casuarina and coconut saplings on its coast as a natural barrier against future tsunamis like the 2004 Indian Ocean earthquake. Studies have found that a tsunami wall could reduce tsunami wave heights by up to 83%. The design and type of sea wall that is appropriate depends on aspects specific to the location, 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 reefs and mangrove forests, prevent the spread of tsunamis. A cost benefit approach is a way to determine whether a seawall is appropriate. Besides controlling erosion, consideration must be given to the effects of hardening a shoreline on natural coastal ecosystems, a seawall 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 summarises some positive and negative effects of seawalls which can be used when comparing their effectiveness with other coastal management options, such as beach nourishment
11.
Dune
–
In physical geography, a dune is a hill of loose sand built by wind or the flow of water. Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water, most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter slip face in the lee of the wind. The valley or trough between dunes is called a slack, a dune field is an area covered by extensive sand dunes. Dunes occur, for example, in deserts and along some coasts. Some coastal areas have one or more sets of dunes running parallel to the shoreline directly inland from the beach, in most cases, the dunes are important in protecting the land against potential ravages by storm waves from the sea. Although the most widely distributed dunes are those associated with coastal regions, Dunes can form under the action of water flow, and on sand or gravel beds of rivers, estuaries and the sea-bed. The modern word dune came into English from French c,1790, which in turn came from Middle Dutch dūne. Crescent-shaped mounds are generally wider than they are long, the slipfaces are on the concave sides of the dunes. These dunes form under winds that blow consistently from one direction, some types of crescentic dunes move more quickly over desert surfaces than any other type of dune. A group of dunes moved more than 100 metres per year between 1954 and 1959 in Chinas Ningxia Province, and similar speeds have been recorded in the Western Desert of Egypt. The largest crescentic dunes on Earth, with mean crest-to-crest widths of more than three kilometres, are in Chinas Taklamakan Desert. They may be composed of clay, silt, sand, or gypsum, eroded from the floor or shore, transported up the concave side of the dune. Examples in Australia are up to 6.5 km long,1 km wide and they also occur in southern and West Africa, and in parts of the western United States, especially Texas. Straight or slightly sinuous sand ridges typically much longer than they are wide are known as linear dunes and they may be more than 160 kilometres long. Some linear dunes merge to form Y-shaped compound dunes, many form in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement, linear loess hills known as pahas are superficially similar. These hills appear to have formed during the last ice age under permafrost conditions dominated by sparse tundra vegetation. Radially symmetrical, star dunes are pyramidal sand mounds with slipfaces on three or more arms that radiate from the center of the mound
12.
Ardennes
–
The Ardennes is a region of extensive forests, rough terrain, rolling hills and ridges formed by the geological features of the Ardennes mountain range and the Moselle and Meuse River basins. Geologically, the range is a extension of the Eifel. The eastern part of the Ardennes forms the northernmost third of the Grand Duchy of Luxembourg, also called Oesling, the greater region maintained an industrial eminence into the 20th century after coal replaced charcoal in metallurgy. The region is typified by steep-sided valleys carved by swift-flowing rivers and its most populous cities are Verviers in Belgium and Charleville-Mézières in France, both exceeding 50,000 inhabitants. The Ardennes is otherwise relatively sparsely populated, with few of the cities exceeding 10,000 inhabitants with a few exceptions like Eupen or Bastogne. The Eifel range in Germany adjoins the Ardennes and is part of the geological formation. N. B. the Belgian Province of Luxembourg in the above list is not to be confused with the known as the Grand Duchy of Luxembourg. The Ardennes is an old mountain formed during the Hercynian orogeny, in France similar formations are the Armorican Massif, the Massif Central, the low interior of such old mountains often contain coal, plus iron, zinc and other metals in the sub-soil. This geologic fact explains the greatest part of the geography of Wallonia, the region was uplifted by a mantle plume during the last few hundred thousand years, as measured from the present elevation of old river terraces. This geological region is important in the history of Wallonia because this old mountain is at the origin of the economy, the history, Wallonia presents a wide range of rocks of various ages. Some geological stages internationally recognized were defined from rock sites located in Wallonia, except for the Tournaisian, all these rocks are within the Ardennes geological area. Before the 19th century industrialization, the first furnaces in the four Walloon provinces and in the French Ardennes used charcoal for fuel and this industry was also in the extreme south of the present-day Belgian province of Luxembourg, in the region called Gaume. Wallonia became the industrial power area of the world in proportion to its territory. The rugged terrain of the Ardennes limits the scope for agriculture, arable, the region is rich in timber and minerals, and Liège and Namur are both major industrial centres. The extensive forests have an abundant population of wild game, the scenic beauty of the region and its wide variety of outdoor activities, including hunting, cycling, walking and canoeing, make it a popular tourist destination. The region took its name from the ancient Silva, a vast forest in Roman times called Arduenna Silva, the modern Ardennes covers a much smaller area. The Song of Roland describes Charlemagne as having a nightmare the night before the Battle of Roncevaux Pass of 778 and this nightmare took place in the Ardennes forest, where his most important battles occurred. Another song about Charlemagne, the Old French 12th-century chanson de geste Quatre Fils Aymon, mentions many of Wallonias rivers, villages and other places

Vaalserberg
–
The Vaalserberg is a hill with a height of 322.7 metres above NAP and the highest point in mainland Netherlands. The Vaalserberg is located in the province of Limburg, at the south-easternmost edge of the country, after the Dutch possessions in the Caribbean were incorporated into the Kingdom of the Netherlands, the Vaalserberg was replaced as the Netherlands highest mountain by Mount Scenery. On the Belgian side, the tripoint borders the region of Wallonia, between 1830 and 1919, the summit was a quadripoint, also bordering Neutral Moresnet - today part of Belgiums German speaking areas. The current Belgian-German-border is not the same as the eastern border of Moresnet with Prussia. Therefore, five different borders came together at this point, however never more than four at one time - except possibly for the period 1917-1920, when the border situation was unclear and disputed. This border intersection has made the Vaalserberg a well-known tourist attraction in the Netherlands with a tower on the Belgian side offering a panorama of the surrounding landscape. The road leading up to point on the Dutch side is called the Viergrenzenweg. The names of the roads in Belgium and Germany only refer to three, the Vaalserberg is often used in the Amstel Gold Race and is climbed halfway through the race. The climb is named in the roadbook of the Gold Race as Drielandenpunt and is followed by the Gemmenich climb, list of mountains and hills in North Rhine-Westphalia

Belgium

Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, today, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments. Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is also a member of the Eurozone, NATO, OECD and WTO. Its capital, Brussels, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is also a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands. The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie

Meuse
–
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. It has a length of 925 km. Its lower Belgian portion, part of the sillon industriel, was the first fully industrialized area in continental Europe. The Meuse and its crossings were a key objective of the last major German WWII counter-offensive on the Western Front, the Meuse River is represented in the documentary The River People released in 2012 by Xavier Istasse. The name Meuse is derived from the French name of the river, the Dutch name Maas descends from Middle Dutch Mase, which comes from the presumed but unattested Old Dutch form *Masa, from Proto-Germanic *Masō. Only modern Dutch preserves this Germanic form, however, despite the similarity, the Germanic name is not derived from the Latin name, judging from the change from earlier o into a, which is characteristic of the Germanic languages. Therefore, both the Latin and Germanic names were derived from a Proto-Celtic source, which would have been *Mosā. The Meuse rises in Pouilly-en-Bassigny, commune of Le Châtelet-sur-Meuse on the Langres plateau in France from where it flows northwards past Sedan, at Namur it is joined by the River Sambre. Beyond Namur the Meuse winds eastwards, skirting the Ardennes, the river then forms part of the Belgian-Dutch border, except that at Maastricht the border lies further to the west. The river has been divided near Heusden into the Afgedamde Maas on the right, the Bergse Maas continues under the name of Amer, which is part of De Biesbosch. Near Lage Zwaluwe, the Nieuwe Merwede joins the Amer, forming the Hollands Diep, between Maastricht and Maasbracht, an unnavigable section of the Meuse is bypassed by the 36 km Juliana Canal. South of Namur, further upstream, the river can carry more modest vessels. From Givet, the river is canalized over a distance of 272 kilometres, the canalized Meuse used to be called the Canal de lEst — Branche Nord but was recently rebaptized into Canal de la Meuse. The waterway can be used by the smallest barges that are still in use commercially, just upstream of the town of Commercy, the Canal de la Meuse connects with the Marne–Rhine Canal by means of a short diversion canal. The Cretaceous sea reptile Mosasaur is named after the river Meuse, the first fossils of it were discovered outside Maastricht 1780. An international agreement was signed in 2002 in Ghent, Belgium about the management of the river amongst France, Germany, Luxembourg, the Netherlands, also participating in the agreement were the Belgian regional governments of Flanders, Wallonia, and Brussels. Most of the area is in Wallonia, followed by France. An International Commission on the Meuse has the responsibility of the implementation of the treaty, the map of the basin area of Meuse was joined to the text of the treaty

Geographic coordinates
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Amersfoort
–
Amersfoort is a municipality and the second largest city of the province of Utrecht in central Netherlands. The city is growing quickly but has a well-preserved and protected medieval centre, Amersfoort is one of the largest railway junctions in the country, because of its location on two of the Netherlands main east-west and north-south rail lines. It celebrated its 750th birthday as a city in 2009, hunter gatherers set up camps in the Amersfoort region in the Mesolithic period. Archaeologists have found traces of these camps, such as the remains of hearths, the city grew around what is now known as the central square, the Hof, where the Bishops of Utrecht established a court in order to control the Gelderse Vallei area. It was granted city rights in 1259 by the bishop of Utrecht, a first defensive wall, made out of brick, was finished around 1300. Soon after, the need for enlargement of the city became apparent and around 1380 the construction of a new wall was begun, the famous Koppelpoort, a combined land and water gate, is part of this second wall. The first wall was demolished and houses were built in its place, todays Muurhuizen Street is at the exact location of the first wall, the fronts of the houses are built on top of the first city walls foundations. The Onze-Lieve-Vrouwentoren tower is one of the tallest medieval church towers in the Netherlands at 98 metres, the construction of the tower and the church was started in 1444. It is now the point of the RD coordinate system, the coordinate grid used by the Dutch topographical service. The inner city of Amersfoort has been preserved well since the Middle Ages, in the Middle Ages, Amersfoort was an important centre for the textile industry, and there were a large number of breweries. In the 18th century the city flourished because of the cultivation of tobacco, after the 1920s growth stalled again, until in 1970 the national government designated Amersfoort, then numbering some 70,000 inhabitants, as a growth city. In 2009 the population was 140,000 plus, with an expected 150,000 by 2012, after four days of battle, the population was allowed to return. There was a functioning Jewish community in the town, at the beginning of the war numbering about 700 people, half of them were deported and killed, mainly in Auschwitz and Sobibor. In 1943, the synagogue, dating from 1727, was damaged on the orders of the then Nazi-controlled city government. It was restored and opened again after the war, and has served since by a succession of rabbis. There was a camp near the city of Amersfoort during the war. The camp, officially called Polizeiliches Durchgangslager Amersfoort, better known as Kamp Amersfoort, was located in the neighbouring municipality of Leusden. After the war the leader of the camp, Joseph Kotälla and he died in captivity in 1979

Solar time
–
Solar time is a calculation of the passage of time based on the position of the Sun in the sky. The fundamental unit of time is the day. Two types of time are apparent solar time and mean solar time. Fix a tall pole vertically in the ground, at some instant on any day the shadow will point exactly north or south. That instant is local apparent noon,12,00 local apparent time, about 24 hours later the shadow will again point north/south, the Sun seeming to have covered a 360-degree arc around the Earths axis. When the Sun has covered exactly 15 degrees, local apparent time is 13,00 exactly, after 15 more degrees it will be 14,00 exactly. As explained in the equation of time article, this is due to the eccentricity of the Earths orbit, the effect of this is that a clock running at a constant rate – e. g. This is mean solar time, which is not perfectly constant from one century to the next but is close enough for most purposes. Currently a mean solar day is about 86,400.002 SI seconds, the two kinds of solar time are among the three kinds of time reckoning that were employed by astronomers until the 1950s. By the 1950s it had become clear that the Earths rotation rate was not constant, so astronomers developed ephemeris time, the apparent sun is the true sun as seen by an observer on Earth. Apparent solar time or true solar time is based on the apparent motion of the actual Sun and it is based on the apparent solar day, the interval between two successive returns of the Sun to the local meridian. Solar time can be measured by a sundial. The equivalent on other planets is termed local true solar time, the length of a solar day varies through the year, and the accumulated effect produces seasonal deviations of up to 16 minutes from the mean. The effect has two main causes, first, Earths orbit is an ellipse, not a circle, so the Earth moves faster when it is nearest the Sun and slower when it is farthest from the Sun. Second, due to Earths axial tilt, the Suns annual motion is along a circle that is tilted to Earths celestial equator. In June and December when the sun is farthest from the equator a given shift along the ecliptic corresponds to a large shift at the equator. So apparent solar days are shorter in March and September than in June or December and these lengths will change slightly in a few years and significantly in thousands of years. Mean solar time is the angle of the mean Sun plus 12 hours

Altitude
–
Altitude or height is defined based on the context in which it is used. As a general definition, altitude is a measurement, usually in the vertical or up direction. The reference datum also often varies according to the context, although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the direction are commonly referred to as depth. In aviation, the altitude can have several meanings, and is always qualified by explicitly adding a modifier. Parties exchanging altitude information must be clear which definition is being used, aviation altitude is measured using either mean sea level or local ground level as the reference datum. When flying at a level, the altimeter is always set to standard pressure. On the flight deck, the instrument for measuring altitude is the pressure altimeter. There are several types of altitude, Indicated altitude is the reading on the altimeter when it is set to the local barometric pressure at mean sea level. In UK aviation radiotelephony usage, the distance of a level, a point or an object considered as a point, measured from mean sea level. Absolute altitude is the height of the aircraft above the terrain over which it is flying and it can be measured using a radar altimeter. Also referred to as radar height or feet/metres above ground level, true altitude is the actual elevation above mean sea level. It is indicated altitude corrected for temperature and pressure. Height is the elevation above a reference point, commonly the terrain elevation. Pressure altitude is used to indicate flight level which is the standard for reporting in the U. S. in Class A airspace. Pressure altitude and indicated altitude are the same when the setting is 29.92 Hg or 1013.25 millibars. Density altitude is the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions, aircraft performance depends on density altitude, which is affected by barometric pressure, humidity and temperature. On a very hot day, density altitude at an airport may be so high as to preclude takeoff and these types of altitude can be explained more simply as various ways of measuring the altitude, Indicated altitude – the altitude shown on the altimeter

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Germany
–
Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

Nautical mile
–
A nautical mile is a unit of measurement defined as exactly 1852 meters. Historically, it was defined as one minute of latitude, which is equivalent to one sixtieth of a degree of latitude. Today it is an SI derived unit, being rounded to a number of meters. The derived unit of speed is the knot, defined as one mile per hour. The geographical mile is the length of one minute of longitude along the Equator, there is no internationally agreed symbol. M is used as the abbreviation for the mile by the International Hydrographic Organization and by the International Bureau of Weights. NM is used by the International Civil Aviation Organization, nm is used by the U. S. National Oceanic and Atmospheric Administration. Nmi is used by the Institute of Electrical and Electronics Engineers, the word mile is from the Latin word for a thousand paces, mīlia. In 1617 the Dutch scientist Snell assessed the circumference of the Earth at 24,630 Roman miles, around that time British mathematician Edmund Gunter improved navigational tools including a new quadrant to determine latitude at sea. He reasoned that the lines of latitude could be used as the basis for a unit of measurement for distance, as one degree is 1/360 of a circle, one minute of arc is 1/21600 of a circle. These sexagesimal units originated in Babylonian astronomy, Gunter used Snells circumference to define a nautical mile as 6,080 feet, the length of one minute of arc at 48 degrees latitude.3 metres. Other countries measure the minute of arc at 45 degrees latitude, in 1929, the international nautical mile was defined by the First International Extraordinary Hydrographic Conference in Monaco as 1,852 meters. Imperial units and United States customary units used a definition of the nautical mile based on the Clarke Spheroid, the United States nautical mile was defined as 6,080.20 feet based in the Mendenhall Order foot of 1893. It was abandoned in favour of the nautical mile in 1954.181 meters. It was abandoned in 1970 and, legally, references to the unit are now converted to 1,853 meters. Conversion of units Orders of magnitude
