Ara Canal

The Ara Canal or Gyeongin Ara Waterway (Hangul: 경인 아라뱃길) is a canal in South Korea, linking the Han River to the Yellow Sea. It extends from Incheon district Seo-gu to Seoul Gangseo-gu. It was built in 2012. The purpose of the canal is to provide flood control and to facilitate leisure pursuits.

History

Choe I, son of Choe Chung-heon, attempted to construct a canal in the Goryeo period. It failed as it was technologically unfeasible. One of the Joseon kings also tried and failed.

The Gulpocheon river "waterproof road" project was started in 1992. Gulpocheon's limitation was lack of water flow. In particular, there was a flood in the summer of 1987, resulting in six thousand flood victims in the Incheon area. To solve this problem, Gulpocheon waterproofing was undertaken, starting with a five-year survey. In 1995, the Gyeongin canal project was planned, and controversies followed over the next 20 years.

The project was started in 2009 and completed in 2012.[1]

Controversy

Controversy over the construction of the Ara canal can be traced back to 1995. The Gulpocheon waterproof project was examined according to several scenarios. One scenario was to dig the waterway in such a way as to discharge water into the Yellow Sea. Another was that the municipality of Gimpo would turn the area into a reservoir. Though the latter was more economical, the government selected the former way in order to boost Korea's economy.

The waterway extended in the direction of the Yellow Sea (width: 40~80m, length: 14.2 km). They also constructed a 3.8 km length of waterway to the Hangang river. After long discussion, the government carried forward to private sector investment and Hyudai Engineering & Construction was selected as the main business operator in 1995.

With no economic benefit and a negative effect on the ecosystem, public opinion turned against the project. Business operator and Ministry of Construction and Transportation submitted an 'economic analysis' and demand prediction report to demonstrate the project's validity. As a result, eight reports were made for Gyeongin Ara canal. The cost-benefit report about Gyeongin Ara canal submitted by Korea water resources corporation gained 2.08 and 2.2 scores in 1996. However, when the IMF crisis occurred, the project was cut.

After the IMF crisis passed, the ministry of construction and transportation requested a KDI report of demand prediction and cost analysis in 2002. This time the score was 0.8166 and on reanalysis the score remained below 1. They rejected the report and delayed service cost to adjust report. The KDI resubmitted report by eight scenario including method of main traffic road and whether road charging or not. The result is 0.9223 to 1.2807. However, in 2003, the board of audit and inspection of Korea confirmed inflated result. So they stopped this project and requested disciplinary action.

In August 2004, the ministry of construction and transportation assigned project's report service to Netherlands company and got a 1.76 score in March 2007. In 2008, KDI investigated this report again and submitted score result 1.065. Also predicted the quantity of goods transported in 2011 was 290 thousand 4000 TEU related to container, 6.3 million ton related to sea sand, 5 million ton related to steel, 6 million related to passenger. At this point, 80 percent of container and 53 percent of sea sand are included the quantity of goods transported in yellow sea. Also the tailrace which discharged water to hanyang river was completed in width 80 m. It was decision to consider Ara canal. The member of the national assembly of opposition party said that if government don't consider the Ara canal, the width is enough to 40 m.[3]

This controversy reappeared during the project period. In the summer of 2010, there was damage in the nearby Ara canal region, due to heavy rain. Environment groups insisted that this project has no effect to prevent disaster, like flood or heavy rain. Also they said that the Ara canal has no plan to build 'rain water pump station', 'rain water pipe' and so on. So they demanded that this project be reexamined. But Korea Water Resource Corporation insisted that if the Ara canal has not existed, this had great damage. This damage was due to lack of capacity in pipe conduit. The Ara canal help to prevent a great damage to flow rainwater. Also the Ara canal's role is to flow rainwater to Yellow sea by preventing flood. So installing 'rain water pump station' and 'rain water pipe' and others are not related to this project.[4]

Sport

Bicycle

In "Ara Waterway", there is a 41.3 km bicycle path[7]

There are five bicycle rental shops in Ara Waterway.

Marina port

Ara Marina

There are three facilities in the Ara Marina region.

The yacht mooring facility accommodates 199 ships (water: 136, land: 58). The marina support facility has a "ship gas station", "ship repair shop", "crane", "inclined plane", "washing room", "sewage disposal". Also in the Ara marine center, there is a convention center, wedding hall and restaurant.[9] In late May, the Gimpo mayor yacht contest is held.

Cultural life

Gyeongin Ara Culture Festival

'Gyeongin Ara Culture Festival' was first held in October 2013. It is a nine-day festival.[10] The program has changed every year. The programs are divided by region, Incheon jeongseojin.

The shopping mall opened in February 2015.[11] It is the largest shopping mall in the Ara canal region.

Notes

gollark: POST data isn't in the URL though, it's sent as the body.
gollark: The reason they *do* is probably just consistency with other methods (it would be very annoying if they worked very differently to GET routing-wise) and so requests can be routed to the right handler more easily.
gollark: <@498244879894315027> Why wouldn't (shouldn't?) they have a URL?
gollark: They do have to spin pretty fast. There are sealed helium ones now.
gollark: > The HDD's spindle system relies on air density inside the disk enclosure to support the heads at their proper flying height while the disk rotates. HDDs require a certain range of air densities to operate properly. The connection to the external environment and density occurs through a small hole in the enclosure (about 0.5 mm in breadth), usually with a filter on the inside (the breather filter).[124] If the air density is too low, then there is not enough lift for the flying head, so the head gets too close to the disk, and there is a risk of head crashes and data loss. Specially manufactured sealed and pressurized disks are needed for reliable high-altitude operation, above about 3,000 m (9,800 ft).[125] Modern disks include temperature sensors and adjust their operation to the operating environment. Breather holes can be seen on all disk drives – they usually have a sticker next to them, warning the user not to cover the holes. The air inside the operating drive is constantly moving too, being swept in motion by friction with the spinning platters. This air passes through an internal recirculation (or "recirc") filter to remove any leftover contaminants from manufacture, any particles or chemicals that may have somehow entered the enclosure, and any particles or outgassing generated internally in normal operation. Very high humidity present for extended periods of time can corrode the heads and platters. https://en.wikipedia.org/wiki/Hard_disk_drive#Integrity
