The Han River and its surrounding area have played an important role in Korean history. The Three Kingdoms of Korea strove to take control of this land, where the river was used as a trade route to China (via the Yellow Sea).[2] The river is no longer actively used for navigation because its estuary is located at the borders of the two Koreas, and civilian entry is barred.
The river serves as a water source for over 12 million South Koreans. In July 2000, the United States military admitted to having dumped formaldehyde in the sewer system connected to the river, which caused protests.[3]
The lower stretches of the Han River are lined with pedestrian walkways, bicycle paths, public parks and restaurants, particularly in Seoul. In a 2011 survey conducted by Seoul Development Institute of 800 residents and 103 urban planning and architectural experts, 51% of residents and 69% of experts voted the river the second most scenic location in the city, following Mount Namsan in the top spot.[4]
The hanja word for "Hangang" does not stand for Шаблон:Lang ("Korea") but rather Шаблон:Lang (Chinese). The reason behind this is because the meaning of the native Korean "han" (한), in this instance meaning "great" "large" "wide", was transliterated into Hanja with the character Шаблон:Lang also meaning "large", thus showing the reason why the river used the word Шаблон:Lang instead of Шаблон:Lang. It is also easily mistaken with the use of Шаблон:Lang in Seoul's older name, "漢城" where Шаблон:Lang does not refer to Chinese people, but refers to the idea of Seoul being the "walled city on the Han River." As a result, Koreans rarely use 漢 because 韓 and 漢 sound the same (han), but the meaning is 韓 (han, 한, "Korean"), not "Han Chinese". Шаблон:Citation needed
The Han River has been called by different names through the course of Korean history. During the early part of the Three Kingdoms period the river was often referred to as the Daesu (Шаблон:Lang; "the Regional Waters"). The state of Goguryeo called it the Arisu (Шаблон:Lang; "The Gainful Waters"). Baekje called it the Ungniha (Шаблон:Lang; "Fragrant Mile River"), while the kingdom of Silla termed it the Iha (Шаблон:Lang; "Muddy River").[5]
History
The Han River has played a central role in Korean history from the earliest times. The kingdom of Baekje was the first to lay claim to the Han River, recognizing its strategic significance as a primary waterway linking the central western region of the peninsula with the Yellow Sea. It was also recognized for the river's fertile alluvial banks, a relative rarity on the mountainous peninsula. Pungnaptoseong, located south of Seoul, is posited as an early capital of Baekje. It was not long before the region near its mouth became a bone of contention between Baekje and the rising kingdom of Goguryeo. During the 5th century reign of King Jangsu, Goguryeo wrested the western terminus of the river from Baekje. The ensuing decades would see a tug-of-war over the region until 551 when Baekje, in an alliance with Silla, confirmed its control over the Han River basin. But this alliance was not to last, and in 553 Silla broke its alliance with Baekje to seize control of the entire river as part of its bid for domination of the peninsula.[6]
With the demise of both Baekje and Goguryeo and then the unification of the peninsula under Silla in 668, the Han River entered its long era as a "Korean river". During the Joseon period the Han River achieved prominence as the primary waterway of the Korean capital of Seoul, then called Hanyang.
During the first few decades of South Korea's existence, the Han River became a byword for pollution, as burgeoning industry and an impoverished populace used it as a convenient spillway for industrial and urban refuse. Though it no longer plays a central role in commerce or transportation, it is a prime fixture in the life of the South Korean capital and in the last decade has become the focus of government sponsored environmental efforts to clean it up and transform it into an ecological jewel of the capital. During the 1988 Summer Olympics in Seoul, the Han River was the site of the Olympic rowing regatta.[7]
There have been fears, such as the 1986 Water Panic in South Korea, that North Korea could attack Seoul by releasing waters from upstream dams, creating floods downstream.[8] In July 2000, the US military admitted to dumping 20 gallons (75.7 liters) of diluted formaldehyde in the sewer system connected to the river. As the river serves as a drinking source for some 12 million South Koreans, some South Koreans launched large protests and accused the US military of ignoring South Korea's environmental regulations. Activists lobbed toy rockets—filled with water from the river—into the main US Army base. The political party Green Party Korea had earlier accused the US of dumping nearly 60 gallons of the toxic chemical into the river, and said that "... if people are exposed to the chemical for a long period of time, it could cause lung cancer [and when] dissolved into water, it could kill fish and other aquatic creatures."[9][10] The events inspired Bong Joon-ho's acclaimed 2006 film The Host.
In 2012 the 18-kilometer Ara Canal was completed,[11] linking the Han River near Gimpo in Seoul to Incheon. It can accommodate both large container and passenger vessels.
Joint Utilization Zone
On November 4, 2018, a 20-member team consisting of 10 people from North Korea and 10 people from South Korea began a joint inter-Korean survey which will lead to the development a Joint Utilization Zone along the Han River's estuary.[12][13] The zone will allow civilians to access the estuary for tourism, ecological protection and the collection of construction aggregate under the protection of militaries from both sides of the Korean border.[12][13] On November 5, 2018, the councils of South Korea's Gangwon and Gyeonggi provinces, which border the DMZ, signed a “peace working agreement” at Dorasan Station in Paju, giving local approval to the Joint Utilization Zone.[14]
The total length of the Han River is approximately Шаблон:Convert.[17][18] Although it is not a long river, the lower Han River is remarkably broad. Within Seoul city limits, the river is more than Шаблон:Convert wide. Prior to the construction of several major dams, the river was known for its huge coefficient of river regime (ratio between the maximum and minimum amount of flow) of 1:39. (For comparison, The Thames and the Rhine have coefficients of 1:8 and 1:18, respectively.)[19]
