Water Board (Netherlands)
In the Netherlands, a water board, water council or water authority () is a regional governing body solely charged with the management of surface water in the environment. Water boards are independent of administrative governing bodies like provinces and municipalities. In general, they are responsible for managing rivers and canals, issues with the flow of watercourses and drainage issues, water collection, flood and erosion prevention and provision of potable water. They manage polder systems, water levels, water barriers and Lock (water navigation), locks, enforcements, water quality and sewage treatment in their respective regions. The concept of a coordinating "High Water Authority" (''Hoogheemraadschap'') originated in what now is the province of South Holland in the 12th century. Background Since the settlement of the Netherlands, large parts of the land have been constantly threatened by rivers and the sea. Fertile soil and peatlands often were located near rivers, thu ...

Sugar City 5
Sugar is the generic name for Sweetness, sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two Glycosidic bond, bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is almost pure sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars and are called oligosaccharides or polysaccharides. Starch is a glucose polymer found in plants, the most abundant source of energy in human food. Some other chemical substances, such as ethylene glycol, glycerol and sugar alcohols, may have a sweet taste but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control In The Netherlands
Flood control is an important issue for the Netherlands, as due to its low elevation, approximately two thirds of its area is vulnerable to flooding, while the country is densely populated. Natural sand dunes and constructed Dike (construction), dikes, dams, and floodgates provide defense against storm surges from the sea. River dikes prevent flooding from water flowing into the country by the major rivers Rhine and Meuse (river), Meuse, while a complicated system of drainage ditches, canals, and pumping stations (historically: windmills) keep the low-lying parts dry for habitation and agriculture. Water board (Netherlands), Water control boards are the independent local government bodies responsible for maintaining this system. In modern times, Floods in the Netherlands, flood disasters coupled with technological developments have led to large construction works to reduce the influence of the sea and prevent future floods. These have proved essential over the course of Dutch his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeeland
Zeeland (; ), historically known in English by the Endonym and exonym, exonym Zealand, is the westernmost and least populous province of the Netherlands. The province, located in the southwest of the country, borders North Brabant to the east, South Holland to the north, as well as the country of Belgium to the south and west.

Holland
Holland is a geographical regionG. Geerts & H. Heestermans, 1981, ''Groot Woordenboek der Nederlandse Taal. Deel I'', Van Dale Lexicografie, Utrecht, p 1105 and former provinces of the Netherlands, province on the western coast of the Netherlands. From the 10th to the 16th century, Holland proper was a unified political region within the Holy Roman Empire as a county ruled by the counts of Holland. By the 17th century, the province of Holland had risen to become a maritime and economic power, dominating the other provinces of the newly independent Dutch Republic. The area of the former County of Holland roughly coincides with the two current Provinces of the Netherlands, Dutch provinces of North Holland and South Holland into which it was divided, and which together include the Netherlands' three largest cities: the Capital of the Netherlands, capital city (Amsterdam), the home of Port of Rotterdam, Europe's largest port (Rotterdam), and the seat of government (The Hague).

William II Of Holland
William II (February 1227 – 28 January 1256) was the Count of Holland and Zeeland from 1234 until his death. He was elected anti-king of Germany in 1248 and ruled as sole king from 1254 onwards. Early life William was the eldest son and heir of Count Floris IV of Holland and Matilda of Brabant.M. A. Pollock, Scotland, ''England and France After the Loss of Normandy, 1204-1296'', (The Boydell Press, 2015), xv. When his father was killed at a tournament at Corbie, William was only seven years old. His paternal uncles William and Otto, bishop of Utrecht, were his guardians until 1239. Kingship With the help of his maternal uncle Duke Henry II of Brabant and the Cologne archbishop Konrad von Hochstaden, William was elected king of Germany after Emperor Frederick II was excommunicated by Pope Innocent IV.

Oude Rijn (Utrecht And South Holland)
The Oude Rijn ("Old Rhine") is a branch of the Rhine river delta, delta in the Netherlands, Dutch Provinces of the Netherlands, provinces of Utrecht (province), Utrecht and South Holland, starting west of Utrecht, at Harmelen, and running by a mechanical pumping station into the North Sea at Katwijk. Its present-day length is 52 kilometres. In ancient times, it was the lower part of the main River Rhine, which forked at the Betuwe into a northern branch, the Rhine, and a southern branch, the Waal (river), Waal. The Oude Rijn was then much wider than it is now, and tidal. During the Ancient Rome, Roman occupation, the river formed part of the northern border of the Roman Empire, Empire. In medieval times, the Lek (river), River Lek became the main outlet for the Rhine, and the Oude Rijn silted up. The river was still important as a drain for the surrounding lowlands, for the clay industry, and as a transport and trade route. Ships were towed by horse and human power, using a towpath ...

Count Of Holland
The counts of Holland ruled over the County of Holland in the Low Countries between the 10th and the 16th century. The Frisian origins While the Frisian kingdom had comprised most of the present day Netherlands, the later province of Friesland in the Netherlands was much reduced. Already in the early Middle Ages West-Frisia (Frisia west of the Vlie) was not considered to be a part of Frisia anymore, and came to be known as Holland (present day provinces North and South Holland and Zeeland). Floris II was the first count who restyled his name from count of "West-Frisia", in count of "Holland". Frisia Proper in medieval time therefore only included the middle and eastern part. The middle part (corresponding to the present day Dutch province of Friesland) was populated by free peasants who successfully resisted all attempts by feudal lords to subdue them, mainly the counts of Holland and the bishops of Utrecht. In the eastern part, local chieftains created their own states (withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Count William II Grants The Charter To The Water Board Of Rhineland, By Caesar Van Everdingen And Pieter Jansz Post
Count (feminine: countess) is a historical title of nobility in certain European countries, varying in relative status, generally of middling rank in the hierarchy of nobility. Pine, L. G. ''Titles: How the King Became His Majesty''. New York: Barnes & Noble, 1992. p. 73. . Especially in earlier medieval periods the term often implied not only a certain status, but also that the ''count'' had specific responsibilities or offices. The etymologically related English term "county" denoted the territories associated with some countships, but not all. The title of ''count'' is typically not used in England or English-speaking countries, and the term ''earl'' is used instead. A female holder of the title is still referred to as a ''countess'', however. Origin of the term The word ''count'' came into English from the French ', itself from Latin '—in its accusative form ''comitem''. It meant "companion" or "attendant", and as a title it indicated that someone was delegated to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windmill
A windmill is a machine operated by the force of wind acting on vanes or sails to mill grain (gristmills), pump water, generate electricity, or drive other machinery. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines have been known earlier, the Babylonian emperor Hammurabi had used wind mill power for his irrigation project in Mesopotamia in the 17th century BC. Later, Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen zur westlichen Windmühle", ''Archiv für Kulturgeschichte'', Vol. 77, Issue 1 (1995), pp. 1–30 (10f.) ...

Pumping Station
Pumping stations, also called pumphouses, are public utility buildings containing pumps and equipment for pumping fluids from one place to another. They are critical in a variety of infrastructure systems, such as water supply, Land reclamation, drainage of low-lying land, canals and removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation. Pumping stations are designed to move water or sewage from one location to another, overcoming gravitational challenges, and are essential for maintaining navigable canal levels, Water supply, supplying water, and managing sewage and floodwaters. In canal systems, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability. Similarly, in land drainage, stations pump water to prevent flooding in areas below sea level, a concept pioneered during the Victorian era in places like The Fens in the UK. The introduction of "package pumping statio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meuse (river)
The Meuse or Maas is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301, the upper Meuse roughly marked the western border of the Holy Roman Empire with the France in the Middle Ages, Kingdom of France, after Count Henry III, Count of Bar, Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV of France, Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III, Duke of Bavaria, John III against the citizens of Liège, who were in open revolt. After the Battle of Othée, battle, which saw the men from Liège defeated, John ordered the drowning in the Meuse of burghers and noblemen in Liège whose loyalties he suspected. The border remained relatively stable until the annexation of the Three Bishoprics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. As extreme weather becomes more intense and the sea level rises due to climate change, storm surges are expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, like coastal dunes or mangroves, improving coastal construction practices and building social strat ...
