Gemeenlandshuis
A Gemeenlandshuis, or Waterschapshuis is a building that is (or was formerly used as) the headquarters of one of the Waterboards of the Netherlands. History Early flood control in the Netherlands is often called the ''Teerschouw'', which loosely translated means "consumption during observation". of the word ''Teerschouw'' This technique was a periodic check of the local dike system by the Dike-reeve and his men. If they found a problem, they would simply go to the nearest house or inn, and stay there for free until the problem was fixed. This was a fairly direct and simple form of |
Gemeenlandshuis Van Rijnland
The Gemeenlandshuis van Rijnland on the Breestraat in Leiden is the oldest Gemeenlandshuis of the Netherlands that kept its function until the current century. Currently, it is still in use by the Hoogheemraadschap van Rijnland, but only for meetings and special occasions. Their day-to-day seat of water management is housed today on the Archimedesweg in Leiden. History The first steps towards a formal method of dike management in Leiden were taken according to Ortelius in Brittenburg, making Leiden the oldest place in the Netherlands to conduct water management. The current building was built to house the Hoogheemraadschap that dates from the 12th century when the Oude Rijn river silted shut at Katwijk. In the centuries afterwards, a group of officials called ''heemraden'' oversaw the dikes along the IJ, the Zyl, the Does, and the dams at Zwammerdam and Spaarndam. Their privileges were described in a document that was given to the dike wardens at Spaarndam in 1255. This was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Board (Netherlands)
In the Netherlands, a water board, water council or water authority ( nl, waterschap or heemraadschap) 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 has been constantly threatened by rivers and the sea. Fertile soil and peatlands ofte ...

Dijkgraaf (official)
A (), sometimes called a , is the chair of a Dutch water board. The dijkgraaf is the equivalent of a mayor in local government and a King's Commissioner in provincial government, chairing both the legislative and executive council, while having both ceremonial and representational roles as well as their own portfolios. The term goes back to pre-medieval days. Literally the term means "Dike count", like other titles ending in (equivalent to English: -grave and german: -graf) of feudal origin, but remained a functional official. The government bodies in the Netherlands today in order of rank are: #National #Provincial #Municipal #Water boards. In medieval times and earlier however, the water boards were the same as municipal, and since it was a country of duchies, the Water board () was in governmental terms the equivalent of a city (), and thus also the highest form of government.

Sugar City 6
Sugar is the generic name for 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 bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is a refined form of 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 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 sources of simple sugars. Sucrose is ... [...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 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, while a complicated system of drainage ditches, canals, and pumping stations (historically: windmills) keep the low-lying parts dry for habitation and agriculture. Water control boards are the independent local government bodies responsible for maintaining this system. In modern times, 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 history, both geographically and militarily, and has greatly impacted the lives of many livi ...

Water Management
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water. Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities. Water resources are under threat from water scarcity, water pollution, water conflict and climate change. Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, with depletion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
