Lauwerszee
Lauwersmeer () is a man-made lake in the north of the Netherlands, on the border of the provinces of Groningen and Friesland. The lake was formed on 23 May 1969, when the dike between the bay called Lauwers Sea and the Wadden Sea was closed. It is noted for birdwatching. On the eastern shores of the Lauwersmeer is the Marnewaard, an exercise area of the Royal Netherlands Army. The central and eastern parts of the lake became Lauwersmeer National Park on 12 November 2003. History The Lauwers Sea (in Dutch: ''Lauwerszee'') was formed by a flood in 1280, and named after the river Lauwers, which flows along the border between the provinces of Groningen and Friesland. During the flood the mouth of the river Lauwers disappeared, and its tributaries the Reitdiep, the Dokkumerdiep, and the Ee flowed directly into the new bay. Many plans were made after this disaster to shut it off from the sea but none was ever put into effect. However, parts of it were empoldered piecemeal, s ...

Lauwersmeer National Park
Lauwersmeer National Park ( nl, Nationaal Park Lauwersmeer) is a national park in the provinces of Friesland and Groningen in the Netherlands. It consists of the southern and eastern parts of the Lauwersmeer (previously Lauwerszee). As part of the Dutch Wadden Sea Conservation Area, it was inscribed on the UNESCO World Heritage List for its outstanding biodiversity and its large, relatively pristine intertidal ecosystem. Geography In the north of the Netherlands, the Lauwers river forms part of the east-west border between the provinces of Friesland and Groningen. The Lauwers flows from south to north into the Wadden Sea. The Lauwersmeer is its estuary, which is connected to the sea via a sluice at Lauwersoog. The national park consists of most of the Lauwersmeer and is situated in the Frisian municipalities of Dongeradeel and Kollumerland c.a. in Friesland and the Groningen municipality of De Marne. History On 25 May 1969, the Lauwers Sea was enclosed and separated from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lauwers
The Lauwers () is a river in the Netherlands. It forms part of the border between the provinces of Friesland and Groningen. From the 730s to Widukind's defeat in 785, it was part of the border of the Frankish Empire. The former Lauwerszee and the present-day Lauwersmeer are both named after the river, which as a small stream has its source southeast of the village of Surhuisterveen. Near Gerkesklooster/Stroobos, it crosses the Prinsesmargrietkanaal/van Starkenborghkanaal. The Lauwers achieves the width of a true river at the place that it gains its tributary, the Oude Vaart, near the Schalkendam. Further along its course, the Lauwers splits into two branches, the Frisian Oude Lauwers and the Zijldiep, in Groningen province. The Lauwers meets the sea at the Wadden Sea The Wadden Sea ( nl, Waddenzee ; german: Wattenmeer; nds, Wattensee or ; da, Vadehavet; fy, Waadsee, longname=yes; frr, di Heef) is an intertidal zone in the southeastern part of the North Sea.

Lauwersoog
Lauwersoog is a seaside village and harbour in the province of Groningen, located in the northern part of the Netherlands. It is part of the municipality of Het Hogeland. It was established on 23 May 1969. The ferry to Schiermonnikoog departs from Lauwersoog. History As part of the Zuiderzee Works, it was decided to transform the Lauwerszee (a bay) into the Lauwersmeer (lake). In 1969, a dike was completed on the border of the provinces of Friesland and Groningen which separates the Lauwersmeer from the Wadden Sea. The village and harbour were named Lauwersoog in 1964 based on a suggestion by Sip Sytsma who worked for the Ministry of Transport and Water Management, to match the nearby islands of Rottumeroog and Schiermonnikoog. The name received some criticism because -oog means island, and it is not an island. On 23 May 1969, Lauwersoog was officially established. There was an agreement to locate the village in Groningen, however the decision was later disputed by Friesland. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sluice
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
North Sea Flood Of 1953
The 1953 North Sea flood was a major flood caused by a heavy storm surge that struck the Netherlands, north-west Belgium, England and Scotland. Most sea defences facing the surge were overwhelmed, causing extensive flooding. The storm and flooding occurred at the end of Saturday, 31 January 1953 and morning of the next day. A combination of a high spring tide and a severe European windstorm over the North Sea caused a storm tide. The combination of wind, high tide, and low pressure caused the sea to flood land up to above mean sea level. Flooding summary In the Netherlands 20% of the land was below mean sea level (subsequently with the expansion of Flevoland this proportion has increased); the next-highest 30% sat at less than above sea level. Such land relies heavily on sea defences and was worst affected, recording 1,836 deaths and widespread damage. Most of the casualties occurred in the southern province of Zeeland. In England, 307 people were killed in the counties of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artificial Lake
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the r ...

Canal Lock
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval en ...

National Park
A national park is a nature park, natural park in use for conservation (ethic), conservation purposes, created and protected by national governments. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. The United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. However, the Tobago Main Ridge Forest Reserve (in what is now Trinidad and Tobago; established in 1776), and the area surrounding Bogd Khan Mountain, Bogd Khan Uul Mountain (Mongolia, 1778), wh ...
