Sleeper Dike
A sleeper dike (in Dutch ''slaperdijk'') is a dike which does not normally face water, but serves as a backup if a "front-line" dike in front of it breaks. The sleeper dikes are usually located at places where there is a high risk of dike breakthrough or where there used to be such a risk. The dike is only potentially safeguarding the land from the sea/river, and is "sleeping", hence the name. Sometimes there is even a secondary sleeper dike, which can be called a " dreamer dike". Many of the sleeper dikes are historical, and no longer have a function in protection against the water, after the dike improvements of the Delta Plan. However, in case of a breakthrough they do divide up the land in sections, and therefore stop the waterflow in some parts, and slow down in others. Also many of these dikes are protected because of their cultural historical and ecological value. References {{DEFAULTSORT:Sleeper Dike Disaster preparedness Geography of the Netherlands Dikes ...

Dutch Language
Dutch ( ) is a West Germanic languages, West Germanic language of the Indo-European language family, spoken by about 25 million people as a first language and 5 million as a second language and is the List of languages by total number of speakers, third most spoken Germanic language. In Europe, Dutch is the native language of most of the population of the Netherlands and Flanders (which includes 60% of the population of Belgium). "1% of the EU population claims to speak Dutch well enough in order to have a conversation." (page 153). Dutch was one of the official languages of South Africa until 1925, when it was replaced by Afrikaans, a separate but partially Mutual intelligibility, mutually intelligible daughter language of Dutch. Afrikaans, depending on the definition used, may be considered a sister language, spoken, to some degree, by at least 16 million people, mainly in South Africa and Namibia, and evolving from Cape Dutch dialects. In South America, Dutch is the native l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dike (construction)
A levee ( or ), dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the banks of a river, often intended to protect against flooding of the area adjoining the river. It is usually earthen and often runs 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 deposited on the banks and settle, forming a ridge that increases the river channel's capacity. Alternatively, levees can be artificially constructed from fill, designed to regulate water levels. In some circumstances, artificial levees can be environmentally damaging. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreamer Dike
The Development, Relief, and Education for Alien Minors Act, known as the DREAM Act, is a United States legislative proposal that would grant temporary conditional residency, with the right to work, for illegal immigrants who entered the United States as minors—and, if they later satisfy further qualifications, they would attain permanent residency. In April 2001, United States Senators Dick Durbin ( D-Illinois) and Orrin Hatch ( R-Utah) first introduced the bill in the Senate as S. 1291, but it did not pass. The proposal has since been reintroduced several times, and approved by a majority in the House and in the Senate, but not by sufficient margins as of 2024. Requirements The beneficiaries of the proposed DREAM Act would have to meet the following requirements to qualify: * Not be inadmissible to or deportable from the United States, or be in Temporary Protected Status (Sec. 3(b)(1)) * Have proof of having arrived in the United States before age 16 (Dream Act of 2017, ...

Delta Plan
The Delta Works () is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine–Meuse–Scheldt delta from the sea. Constructed between 1954 and 1997, the works consist of dams, sluices, locks, dykes, levees, and storm surge barriers located in the provinces of South Holland and Zeeland. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised. Along with the Zuiderzee Works, the Delta Works have been declared one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. History Due to indecision and the Second World War, little action was taken. In 1950 two small estuary mouths, the Brielse Gat near Brielle and the Botlek near Vlaardingen were dammed. After the North Sea flood of 1953, a Delta Works Commission was installed to research the causes and develop measures to prevent such disasters ...

Disaster Preparedness
Emergency management (also Disaster management) is a science and a system charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies; emergencies can be understood as minor events with limited impacts and are managed through the day-to-day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also co ...

Geography Of The Netherlands
The geography of the European Netherlands is unusual in that much of its land has been reclaimed from the sea and is below sea level, protected by dike (construction), dikes. It is a List of countries and dependencies by area, small country with a total area of and ranked List of countries and dependencies by area, 131st. With a population of 17.4 million and density of makes it the second most densely populated member of the European Union after Malta, and the List of sovereign states and dependent territories by population density, 12th most densely populated country in the world, behind only three countries with a population over 16 million. Consequently, the Netherlands is highly urbanized. Statistics Geographic coordinates: The Dutch RD coordinate system (''Rijksdriehoeksmeting'') is also in common use.
