Polder
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as ''koogs'', especially in Germany The ground level in drained marshes subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its previous l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flevopolder Larserbos
The Flevopolder is an island polder forming the bulk of Flevoland, a province of the Netherlands. Created by land reclamation, its northeastern part was drained in 1955 and the remainder—the southwest—in 1968. Boundaries Unlike other major polders, such as Noordoostpolder and Wieringermeer, the Flevopolder is surrounded by bordering lakes or below-sea-level channels. These are the IJsselmeer, the Veluwemeer, Ketelmeer, and Gooimeer. It is the largest artificial island in the world. History Reclamation of its land Levees and dikes were first built around the polder. However, unlike similar projects, the internal water was then drained by diesel and electric pumps. Etymology Its name refers to the ancient Lake Flevo.

Schermer
Schermer () is a former municipality in the Netherlands, in the province of North Holland. The name came from "''skir mere''", which means "bright lake" (ref. Groenedijk, 2000). Since 2015 it has been a part of Alkmaar. The municipality of Schermer included not only the Schermer polder, but also the polders Oterleek, Mijzenpolder, and Eilandspolder. History Around 800 AD, the area that was the municipality of Schermer was covered in peat, and a small river called the Schermer flowed through it. Because of peat-digging by man, and storm floods, this small river had by 1250 developed into an inland lake with an open connection with the Zuyderzee. In the 17th century private investors started draining the largest part of the lake, leaving the southern part, the Alkmaardermeer, intact. In 1635, of polder was drained, whereupon the land was divided among the shareholders. In 1970, the village of Zuid- en Noord-Schermer was merged into Schermer.Ad van der Meer and Onno Boonstra ...

Beemster
Beemster () is a former municipality in the Netherlands, in the province of North Holland. The Beemster is the first so-called polder in the Netherlands that was reclaimed from a lake, the water being extracted from the lake by windmills. The Beemster polder was drained between 1609 and 1612. It has preserved intact its well-ordered landscape of fields, roads, canals, dykes and settlements, laid out in accordance with classical and Renaissance planning principles. A grid of canals parallels the grid of roads in the Beemster. The grids are offset: the larger feeder canals are offset by approximately one kilometer from the larger roads. Beemster merged into the existing municipality of Purmerend on 1 January 2022. Population centres The former municipality of Beemster consisted of the following cities, towns, villages and/or districts: Topography ''Map of the former municipality of Beemster, 2015.''

IJsselmeer
The IJsselmeer (; fy, Iselmar, nds-nl, Iesselmeer), also known as Lake IJssel in English, is a closed off inland bay in the central Netherlands bordering the provinces of Flevoland, North Holland and Friesland. It covers an area of with an average depth of . The river IJssel flows into the IJsselmeer. History Two thousand years ago Pomponius Mela, a Roman geographer, mentioned a complex of lakes at the current location of the IJsselmeer. He called it ''Lacus Flevo''. Over the centuries, the lake banks crumbled away due to flooding and wave action and the lake, now called the Almere, grew considerably. During the 12th and 13th centuries, storm surges and rising sea levels flooded large areas of land between the lake and the North Sea, turning the lake into a bay of the North Sea, called the Zuiderzee. The Zuiderzee continued to be a threat to the Dutch, especially when northwesterly storms funnel North Sea waters towards the English Channel, creating very high tides along ...

Koog
A ''koog'' (plural: ''köge'') or ''groden'' is a type of polder found on the North Sea coast of Germany that is established by the construction of dykes enclosing the land which is then drained to form marshland. This type of land reclamation is also used along rivers. In general, a ''koog'' is protected by embankments known as dykes (''Deiche''). Etymology Unlike the meaning in modern German, Ingvaeonic ''*kāg'', Old Dutch ''*kōg'', modern Dutch ''koog'' and West Frisian Dutch ''kaag'' all designate "land outside the dike". In the Netherlands, it primarily survives in place names (e.g. De Koog, Koog aan de Zaan, Kaag). From the Dithmarschen word ''koch'' (15th and 16th centuries), it went into Danish as ''kog''. In North Frisian it is ''kuch''. The spelling ''koog'' was used by the poet Michael Richey in 1755 and around 1700, what is now the port of Cuxhaven was still called ''Koogshaven''.

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Reclamation
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. The land reclaimed is known as reclamation ground or land fill. In some jurisdictions, including parts of the United States, the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses." In Oceania, it is frequently referred to as land rehabilitation. History One of the earliest large-scale projects was the Beemster Polder in the Netherlands, realized in 1612 adding of land. In Hong Kong the Praya Reclamation Scheme added of land in 1890 during the second phase of construction. It was one of the most ambitious projects ever taken during the Colonial Hong Kong era.Bard, Solomon. 002 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yser
The Yser ( , ; nl, IJzer ) is a river that rises in French Flanders (the north of France), enters the Belgian province of West Flanders and flows through the '' Ganzepoot'' and into the North Sea at the town of Nieuwpoort. The source of the Yser is in Buysscheure (''Buisscheure''), in the Nord department of northern France. It flows through Bollezeele (''Bollezele''), Esquelbecq (''Ekelsbeke''), and Bambecque (''Bambeke''). After approximately of its course, it leaves France and enters Belgium. It then flows through Diksmuide and out into the North Sea at Nieuwpoort. During the Battle of the Yser in the First World War, by opening the sluices, part of the polder west of the Yser was flooded with seawater between Nieuwpoort and Diksmuide to provide an obstacle to the advancing German Army and keep westernmost Belgium safe from German occupation. The Yser river itself never overflowed its banks.Leper, J., Kunstmatige inundaties in Maritiem Vlaanderen 1316-1945, Michiels, Tong ...
