Hantaan River
The Hantan River is a river in South Korea, flowing through Gangwon and Gyeonggi Provinces. It is a tributary of the Imjin River, which eventually joins the Han River and empties into the Yellow Sea. The Hantan River is a popular site for white-water rafting. History The infectious agent ''Hantaan orthohantavirus'' was first identified in the Hantan River area by Dr. Lee Ho-wang. Because his original publications transliterated the river's name idiosyncratically as "Hantaan," this spelling remains associated with the "Hantaan virus." The name is also applied to the virus genus ''Orthohantavirus'' (formerly ''Hantavirus''), as well as its family ''Hantaviridae''. In 2007 construction of the Hantangang Dam began on its lower course. It was expected to be complete in mid-2015. The sole purpose of the dam is flood control. It is also a battleground in the 6/25 war, but the riverside is beautiful, so the Hantang River National Tourist Resort is established. See also * Rivers of ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Rivers Of North Korea
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs ...

Rivers Of Korea
The Korean peninsula is mainly mountainous along its east coast, so most of its river water flows west, emptying into the Yellow Sea. Some of these rivers flow through lakes en route to the coast, but these are all artificial reservoirs, as there are no natural lakes on the Korean mainland. A few rivers head south, emptying into the Korea Strait and some more minor rivers flow east to the East Korea Bay, though these are usually little more than streams in comparison. In the list below, tributaries are listed under the river into which they flow and then in upstream order. They are listed counterclockwise, from the Amnok to the Duman.

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...

Hantangang Dam
The Hantangang Dam is a gravity dam on the Hantan River in Yeoncheon County, Gyeonggi Province, South Korea. Construction on the dam began in 2007 and completed in 2015. The primary purpose of the dam is flood control : it was proposed in 1998 after a series of floods in the late 1990s that killed 128 people, displaced over 31,000 and caused about US$900 million in property damage. Initially designed as a multi-purpose project, the design was changed solely to flood control in 2006 due to the concerns of residents upstream. It is being implemented by Korea Water Resources Corporation (K-water). Construction Construction started in February 2007 and completed in mid-2015. K-water is responsible for planning and supervisionDL E&C(Daelim industrial.co. Ltd) was undertook the construction as a leading contractor. Not only to secure the stability against overflow during the flood season but also to reduce the construction cost through the mechanized construction fitting for the mega con ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Orthohantavirus
''Orthohantavirus'' is a genus of single-stranded, enveloped, negative-sense RNA viruses in the family ''Hantaviridae'' within the order ''Bunyavirales''. Members of this genus may be called orthohantaviruses or simply hantaviruses. Orthohantaviruses typically cause chronic asymptomatic infection in rodents. Humans may become infected with hantaviruses through contact with rodent urine, saliva, or feces. Some strains cause potentially fatal diseases in humans, such as hantavirus hemorrhagic fever with renal syndrome (HFRS), or hantavirus pulmonary syndrome (HPS), also known as hantavirus cardiopulmonary syndrome (HCPS), while others have not been associated with known human disease (e.g. Prospect Hill virus). HPS (HCPS) is a "rare respiratory illness associated with the inhalation of aerosolized rodent excreta (urine and feces) contaminated by hantavirus particles." Human infections of hantaviruses have almost entirely been linked to human contact with rodent excrement; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hantaan Orthohantavirus
''Hantaan orthohantavirus'' (HTNV) is an enveloped, single-stranded, negative-sense RNA virus species of Old World ''Orthohantavirus''. It is the causative agent of Korean hemorrhagic fever in humans. It is named for the Hantan River in South Korea, and in turn lends the name to its genus ''Orthohantavirus'' and family ''Hantaviridae''. Natural reservoir '' Apodemus agrarius'', also known as striped field mouse, is the etiological vector of ''Hantaan orthohantavirus''. Transmission Transmission is believed to be through inhalation of aerosolized rodent urine and feces. Morbidity and mortality In hantavirus induced hemorrhagic fever, incubation time is between two and four weeks in humans before symptoms of infection present. Severity of symptoms depends on the viral load. Like Dobrava-Belgrade virus, Hantaan virus has a mortality rate of 10 to 12%. History During the Korean War (1951–1953), more than 3000 American and Korean troops fell ill with kidney failure, bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
