28-651: Before the commencement of the Maasvlakte project, the region was a sandbank which was hazardous to shipping. The Maasvlakte was created in the 1960s by reclaiming land from the North Sea through dykes and sand suppletion. The sand for the suppletion was largely taken from the North Sea and the Lake of Oostvoorne . This lake was created by the construction of the Maasvlakte. Fossils were (and can still be) found in

56-445: A beach , the term shoal can be applied to larger geological units that form off a coastline as part of the process of coastal erosion, such as spits and baymouth bars that form across the front of embayments and rias . A tombolo is a bar that forms an isthmus between an island or offshore rock and a mainland shore. In places of reentrance along a coastline (such as inlets , coves , rias, and bays), sediments carried by

84-433: A longshore current will fall out where the current dissipates, forming a spit. An area of water isolated behind a large bar is called a lagoon. Over time, lagoons may silt up, becoming salt marshes . In some cases, shoals may be precursors to beach expansion and dunes formation, providing a source of windblown sediment to augment such beach or dunes landforms. Since prehistoric times, humans have chosen some shoals as

112-475: A shoal is a natural submerged ridge , bank , or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation. Shoals are also known as sandbanks , sandbars , or gravelbars . Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as

140-400: A shoal complex . The term shoal is also used in a number of ways that can be either similar to, or quite different from, how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, the term refers to either any relatively shallow place in a stream , lake , sea , or other body of water; a rocky area on the seafloor within an area mapped for navigation purposes; or,

168-480: A beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling , and the waves are said to shoal. The waves may or may not build to the point where they break , depending on how large they were to begin with, and how steep the slope of the beach is. In particular, waves shoal as they pass over submerged sandbanks or reefs. This can be treacherous for boats and ships. Shoaling can also refract waves, so

196-561: A deep water terminal at the Amazonhaven which, in 1990, was sold to EMO. Deep-water access to Rotterdam allows the world's largest ore carriers to visit Rotterdam. The Maasvlakte features various big companies and some smaller ones. Maersk , Europe Container Terminals (ECT), which is a member of the Hutchison Port Holdings group , and Euromax are three big container terminals located here. They can all accommodate

224-410: A growth of vegetation on the bottom of a deep lake, that occurs at any depth, or is used as a verb for the process of proceeding from a greater to a lesser depth of water. Shoals are characteristically long and narrow (linear) ridges. They can develop where a stream , river , or ocean current promotes deposition of sediment and granular material , resulting in localized shallowing (shoaling) of

252-523: A new plant on the same location. There are direct rail links to elsewhere in Europe, especially Germany. The rivers Rhine and Maas enter the sea next to it. This creates good connections for rivergoing vessels. The A15 motorway , which runs into Germany, ends on the Maasvlakte. The Maasvlakte is also the starting point of the Betuweroute freight railway to Germany. An extension, Maasvlakte 2 ,

280-449: A ridge can be further subdivided into smaller geomorphic or structural elements. As in the case of landforms in general, there is a lack of any commonly agreed classification or typology of ridges. They can be defined and classified on the basis of a variety of factors including either genesis, morphology, composition, statistical analysis of remote sensing data, or some combinations of these factors. An example of ridge classification

308-529: A site of habitation. In some early cases, the locations provided easy access to exploit marine resources. In modern times, these sites are sometimes chosen for the water amenity or view, but many such locations are prone to storm damage. An area in Northwest Alabama is commonly referred to as “ The Shoals ” by local inhabitants, and one of the cities, Muscle Shoals , is named for such landform and its abundance of Mussels . Ridge A ridge

336-421: A smaller body of water from the sea, such as: The term bar can apply to landform features spanning a considerable range in size, from a length of a few meters in a small stream to marine depositions stretching for hundreds of kilometers along a coastline, often called barrier islands . They are typically composed of sand , although they could be of any granular matter that the moving water has access to and

364-439: Is a navigation or grounding hazard, with a depth of water of 6 fathoms (11 meters) or less. It therefore applies to a silt accumulation that shallows the entrance to or course of a river, or creek. A bar can form a dangerous obstacle to shipping, preventing access to the river or harbor in poor weather conditions or at some states of the tide . In addition to longshore bars discussed above that are relatively small features of

392-408: Is a long, narrow, elevated geomorphologic landform , structural feature , or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest , with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline . Limitations on the dimensions of a ridge are lacking. Its height above

420-436: Is a sedimentary deposit formed at a harbor entrance or river mouth by the deposition of freshwater sediment or by the action of waves on the sea floor or on up-current beaches. Where beaches are suitably mobile, or the river's suspended or bed loads are large enough, deposition can build up a sandbar that completely blocks a river mouth and dams the river. It can be a seasonally natural process of aquatic ecology , causing

448-524: Is about half-full. The area was formerly used for recreational activities such as kite surfing , and the Slufterbeach nearby was also used as nude beach . Since 2010 the road that ran around the Slufter has been closed to public traffic. A power station located in the area is run by Uniper . It is a coal-fired power station generating 1040 megawatts. It dates from 1988, but there are plans for

476-427: Is capable of shifting around (for example, soil , silt , gravel , cobble , shingle , or even boulders ). The grain size of the material comprising a bar is related to the size of the waves or the strength of the currents moving the material, but the availability of material to be worked by waves and currents is also important. Wave shoaling is the process when surface waves move towards shallow water, such as

504-678: Is that of Schoeneberger and Wysocki, which provides a relatively simple and straightforward system that is used by the USA National Cooperative Soil Survey Program to classify ridges and other landforms. This system uses the dominant geomorphic process or setting to classify different groups of landforms into two major groups, Geomorphic Environments and Other Groupings with a total of 16 subgroups. The groups and their subgroups are not mutually exclusive; landforms, including ridges, can belong to multiple subgroups. In this classification, ridges are found in

532-474: The beach slopes more gradually at one end than the other. Sandbars, also known as a trough bars, form where the waves are breaking, because the breaking waves set up a shoreward current with a compensating counter-current along the bottom. Sometimes this occurs seaward of a trough (marine landform). Sand carried by the offshore moving bottom current is deposited where the current reaches the wave break. Other longshore bars may lie further offshore, representing

560-406: The break point of even larger waves, or the break point at low tide. In Russian tradition of geomorphology , a peresyp is a sandbar that rises above the water level (like a spit ) and separates a liman or a lagoon from the sea. Unlike tombolo bars, a peresyp seldom forms a contiguous strip and usually has one or several channels that connect the liman and the sea. A harbor or river bar

588-464: The distribution of shoes and apparel for all of Europe. Kloosterboer stores mostly chips from the nearby Farm Frites company. On one side of the Maasvlakte is the Slufter . Inside the Slufter, a very deep pit shielded from the surrounding area, toxic waste and polluted sand is stored. When it is filled it will be covered and left there. It is expected to be fully filled around the year 2025; so far it

616-422: The formation of estuaries and wetlands in the lower course of the river. This situation will persist until the bar is eroded by the sea, or the dammed river develops sufficient head to break through the bar. The formation of harbor bars that prevent access for boats and shipping can be the result of: In a nautical sense, a bar is a shoal, similar to a reef : a shallow formation of (usually) sand that

644-494: The sand. An expansion called "Second Maasvlakte" or Maasvlakte 2 was built between September 2008 and May 2013 by spraying sand on the bottom of the North Sea. This project extended the port of Rotterdam by about 2,000 hectares. In 1973 EMO started as the first company at Maasvlakte. They are the biggest bulk terminal in western Europe and are located at the Mississippihaven. In 1989 Frans Swarttouw started building

672-409: The surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional , erosional , tectonic , or a combination of these in origin and can consist of either bedrock , loose sediment , lava , or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently,

700-404: The water. Marine shoals also develop either by the in-place drowning of barrier islands as the result of episodic sea level rise or by the erosion and submergence of inactive delta lobes . Shoals can appear as a coastal landform in the sea , where they are classified as a type of ocean bank , or as fluvial landforms in rivers, streams, and lakes . A shoal–sandbar may seasonally separate

728-402: The waves change direction. For example, if waves pass over a sloping bank which is shallower at one end than the other, then the shoaling effect will result in the waves slowing more at the shallow end. Thus, the wave fronts will refract, changing direction like light passing through a prism. Refraction also occurs as waves move towards a beach if the waves come in at an angle to the beach, or if

756-586: The world's largest ships. On the new Maasvlakte new container terminals will be built. Danish shipping group Maersk has an existing terminal on the original Maasvlakte and will build a new terminal on the second Maasvlakte. With this new terminal Maersk will invest approximately €100 million. A special section has been reserved for large distribution centres: the Rotterdam Distribution Centre. The biggest are Reebok , DHL and Kloosterboer . The Reebok Distribution Centre takes care of

784-642: Was begun in 2008. Maasvlakte 2 will cover 1000 hectares net of industrial sites, located directly on deep water. This new part of the Maasvlakte opened in 2013. To accommodate larger container ships the Maasgeul , which is the channel in the North Sea providing deep-water access to the Rotterdam area, has to be widened to over 800 metres. 51°57′09″N 4°02′47″E  /  51.95250°N 4.04639°E  / 51.95250; 4.04639 Sandbank In oceanography , geomorphology , and geoscience ,
