Fascine Mattress
A fascine mattress , literally sink piece), is a large woven mat made of wikt:brushwood, brushwood, typically willow twigs and shoot (botany), shoots, used to protect riverbeds and other underwater surfaces from Hydrodynamic scour, scour and erosion. They are similar in construction to a fascine, but are primarily used for hydraulic engineering works, typically to strengthen the banks of rivers and streams, as well as coastal structures like revetments and groynes. Modern fascine mattresses utilise a layer of geotextile in order to fulfill the competing requirements of water Permeability (Earth sciences), permeability balanced with the need to be impervious to sand. Prior to the advent of synthetic geotextiles in the 1960s, a layer formed from Reed (plant), reeds was incorporated to make the fascine mattress sand-tight. Fascine mattresses have been used worldwide, but are particularly common in The Netherlands, where significant expertise in their preparation and construction i ...

Goes
The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics. The GOES system uses geosynchronous equatorial satellites that, since the launch of SMS-1 in 1974, have been a basic element of U.S. weather monitoring and forecasting. The procurement, design, and manufacture of GOES satellites is overseen by NASA. NOAA is the official provider of both GOES ...

Biesbosch
De Biesbosch National Park is one of the largest national parks in the Netherlands and one of the last extensive areas of freshwater tidal wetlands in Northwestern Europe. The Biesbosch ('forest of sedges' or 'rushwoods') consists of a large network of rivers and smaller and larger creeks with islands. The vegetation is mostly willow forests, although wet grasslands and fields of reed are common as well. The Biesbosch is an important wetland area for waterfowl and has a rich flora and fauna. It is especially important for migrating geese. Structure National Park The Biesbosch National Park consists of the following major parts: * Sliedrechtse Biesbosch The most northern part of the Biesbosch. This is the part of the Biesbosch with the most significant tidal influence (one of the distinctive characteristics of the Biesbosch). The Sliedrechtse Biesbosch is named after the town of Sliedrecht, which was drowned during the creation of the Biesbosch and was later rebuilt ...

Merwede
The Merwede (; etymology uncertain, possibly derived from the Old Dutch ''merwe'' or ''merowe'', a word meaning "wide water") is the name of several connected stretches of river in the Netherlands, between the cities of Woudrichem, Dordrecht and Papendrecht. The river is part of the Rhine–Meuse–Scheldt delta and is mostly fed by the river Rhine. At first, a disconnected branch of the Meuse joins the Waal at Woudrichem to form the Boven Merwede (Upper Merwede). A few kilometers downstream it splits into the Beneden Merwede (Lower Merwede) on the right and the Nieuwe Merwede (New Merwede) on the left. All these rivers are tidal. The Nieuwe Merwede joins the Bergse Maas near Lage Zwaluwe to form the Hollands Diep estuary, and separates the Island of Dordrecht from the Biesbosch National Park. The Beneden Merwede splits into the Noord River and Oude Maas near Papendrecht. History In medieval times the name Merwede (or "Merwe" in Middle Dutch) was the name of a continuous ...

Osier Bed
An osier bed or osiery is where historically willows were planted and coppiced to produce withies, which were used for basket making, fish-traps, and other purposes. The willow species ''Salix viminalis'', known as the "common osier" was typically, although not exclusively, grown for this purpose. The marshy fringes of rivers, especially those which were often flooded and those with small islands, aits, eyots, or holts, were the most common locations for osier beds. Willow rods (cuttings) would be planted, which root easily in moist ground, and the growth of the willow withies would be cut every one or two years. Osier beds and basket-weaving using willow were a significant industry in Great Britain until the early 20th Century, when industrial machinery and the import of cheaper materials made them unprofitable and commercially unviable.

Nationaal Archief
The Nationaal Archief (NA) is the national archives of the Netherlands, located in The Hague. It houses collections for the central government, the province of South Holland, and the former County of Holland. There is also material from private institutions and individuals with an association to the Dutch government or the political or social history of the Netherlands. The ''Nationaal Archief'' holds the Archives of the Dutch East India Company from 1602–1811, which were, along with related records held by South Africa, India, Sri Lanka and Indonesia, inscribed on UNESCO's Memory of the World Programme Register in 2003 in recognition of their historical value. Recently, the photographic archives of Spaarnestad Photo were included in the Nationaal Archief. It has been announced that Wikipedia will receive user rights over many photos from these archives. The Nationaal Archief also holds material related to The Fagel Collection. The Netherlands Antilles had a separate Nationaal ...

Levee
A levee ( or ), dike (American English), dyke (British English; see American and British English spelling differences#Miscellaneous spelling differences, spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the river banks, banks of a river, often intended to flood control, protect against flooding of the area adjoining the river. It is usually soil, earthen and often runs parallel (geometry), parallel to the course of a river in its floodplain or along low-lying coastlines. Naturally occurring levees form on river floodplains following flooding. Sediment and alluvium are deposition (geology), deposited on the banks and settle, forming a ridge that increases the river channel's capacity. Alternatively, levees can be artificially constructed from fill dirt, fill, designed to regulate water levels. In some circumstances, artificial levees can be environmental degradation, environmentally damaging. Ancient civilization ...

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

Andries Vierlingh
Andries Vierlingh (Breda, circa 1507 - Steenbergen 1579) was a Dutch civil engineer. His manuscript ''Tractaet van Dyckagie'' is seen as a warning against fundamental engineering errors in waterstaat water management, from which lessons can still be learned today. Life and work He came from a wealthy regent family. He was the son of Nicolaas Vierling, clerk of the council and audit office of the Count of Nassau, and Wilhelmina van Vlyet. He himself was alderman of Breda in 1536 and 1537, and married Emerentia van Bruheze around 1541. He was interested in hydraulic engineering from an early age, because at the age of 20 he was already involved in the restoration of the broken dikes of Reimerswaal. Vierlingh was one of the first hydraulic engineers to combine his work with administrative activities with which, just like Cornelis Lely much later, he brought order to the management of the land inside the dikes with technical knowledge and administrative influence, thus laying the foun ...

Flag Made By F
A flag is a piece of fabric (most often rectangular) with distinctive colours and design. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' (Arabic: ) is equivalent to a brigade in Arab countries. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
