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 utility Gimpo develop the region for a reservoir. Though the latter is 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]

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.
