The Imjin River originates from North Korea and flows to South Korea. About 67% of the total watershed area of 8,117.5 km2 is located in the North Korean region. For this reason, the North Korean water resource development plan has a direct impact on South Korea, which is located downstream. Also, due to the operation of the Hwanggang Dam, there is a risk of water resource reduction and flood damage in downstream of the Imjin River. The Hwanggang Dam is located about 42 km away from the military demarcation line, and the reservoir capacity is estimated to be about 300 to 400 million tons. South Korea is preparing for the discharge of the Hwanggang Dam by constructing a Gunnam Flood Control reservoir of about 70 million tons to protect against floods from the upper reaches of the Imjin River. On September 6, 2009, a large discharge from the Hwanggang Dam caused a flood in Yeoncheon-gun in South Korea, which resulted in damage to life and property. Recently, on August 5, 2020, the water level at the ‘Pil-Seung’ Bridge increased sharply along with heavy rain, and the highest water level ever since observation occurred, and a flood warning was issued and nearby residents were evacuated. |
