⭐ Core Definition: Polder

A polder (Dutch pronunciation: [ˈpɔldər] ) 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:

  1. Land reclaimed from a body of water, such as a lake or the seabed
  2. Flood plains separated from the sea or river by a dike
  3. 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 level, because of peat decomposing when exposed to oxygen from the air.

👉 Polder in the context of Netherlands

The Netherlands is a country in Northwestern Europe, with overseas territories in the Caribbean. It is the largest of the four constituent countries of the Kingdom of the Netherlands. The Netherlands consists of twelve provinces; it borders Germany to the east and Belgium to the south, with a North Sea coastline to the north and west. It shares maritime borders with the United Kingdom, Germany, and Belgium. The official language is Dutch, with West Frisian as a secondary official language in the province of Friesland. Dutch, English, and Papiamento are official in the Caribbean territories. People from the Netherlands are referred to as Dutch.

Netherlands literally means "lower countries", in reference to its low elevation and flat topography, 26% of which is below sea level. Most of the areas below sea level, known as polders, are the result of land reclamation that began in the 14th century. In the Republican period, which began in 1588, the Netherlands entered a unique era of political, economic, and cultural greatness, ranked among the most powerful and influential in Europe and the world; this period is known as the Dutch Golden Age. During this time, its trading companies, the Dutch East India Company and the Dutch West India Company, established colonies and trading posts all over the world. While neutral in the First World War, the Netherlands was invaded and occupied by Nazi Germany in 1940 during the Second World War, which lasted until the end of the war in 1945.

Polder in the context of Marsh

In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants. More in general, the word can be used for any low-lying and seasonally waterlogged terrain. In Europe and in agricultural literature low-lying meadows that require draining and embanked polderlands are also referred to as marshes or marshland.

Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat.

Polder in the context of Purmerend

Purmerend (Dutch pronunciation: [ˌpʏrməˈrɛnt] ) is a city and municipality in the west of the Netherlands, in the province of North Holland. The city is surrounded by polders, such as the Purmer, Beemster and the Wormer. Purmerend's population grew relatively slowly until the 1960s, when it increased from around 10,000 to over 80,000 by 2020. This expansion has turned Purmerend into a commuter town; many inhabitants (14,200 in 2011) work, go to school or spend leisure time in Amsterdam. Purmerend is part of the Randstad, one of the largest conurbations in Europe.

The municipality of Beemster merged into the municipality of Purmerend on 1 January 2022. The extended municipality has a population of about 96,000.

Polder in the context of Flevopolder

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.

Unlike other major polders, it is surrounded by lakes and below-sea-level channels. By some definitions, it is the world's largest artificial island. Levees, dikes, and pumping were used to drain the land. The polder's name references the ancient Lake Flevo. The Flevopolder, along with the Noordoostpolder, forms the Flevoland province, which is located near Amsterdam in the southwest and Kampen, Overijssel in the northeast.

Polder in the context of Markermeer

The Markermeer (Dutch pronunciation: [ˌmɑrkərˈmeːr]) is a 700 km (270 sq mi) lake in the central Netherlands in between North Holland, Flevoland, and its smaller and larger neighbors, the IJmeer and IJsselmeer. A shallow lake at 3 to 5 m in depth, matching the reclaimed land to its west, north-west and east it is named after the small former island, now peninsula, of Marken on its west shore.

The Markermeer was not originally intended to remain a lake. It was formerly part of the Zuiderzee, a saltwater inlet of the North Sea, that was dammed off by the Afsluitdijk (Closure Dike) in 1932, turning the Zuiderzee into the freshwater IJsselmeer. The following years saw the reclamation of extensive tracts of land as large polders in an enormous project known as the Zuiderzee Works. One of these, the Markerwaard, was to occupy the area of the current Markermeer. Part of the construction of this polder was building the Houtribdijk, also called Markerwaarddijk, finished in 1976, which hydrologically splits the IJsselmeer in two, the southern section being the Markermeer.
