flood-affected areas where restoration is being made, point out that damage could be reduced even if the amount of discharge from the upstream dam was well controlled. As a representative example, the Yongdam Dam in the upper reaches of the Geum River is being criticized for causing damage by suddenly flowing a large amount of water and delaying it without increasing the amount of discharge in advance.

the 8th at 12:00 noon, one hour after the emergency evacuation order was issued to the residents of Geumsan, Chungcheongnam-do, Yongdam Dam significantly increased the amount of discharge to three times that of the dawn of the day.

2,900 tons of water per second poured out at once, swallowing up Geumsan's houses and agricultural land in just two hours.

[Jungho Jang/Jaemin Geumsan: All this was a wall. The windows were long, but the water

flowed in, so it drifted away from the current.] The water flowing down here from Yongdam Dam reached Geumsan, Chungcheongnam-do, and Yeongdong-Okcheon, Chungbuk, and had a direct impact on the upper water level of the Geum River. It goes crazy.

Before the flood, we looked at the discharge of Yongdam Dam.

At 12 o'clock on the 7th, the day before, the inflow amount per second was about 2,000 tons, but the amount of discharge was only about 300 tons, 15%, and at 3:40 pm, when the amount of inflow increased, the amount of discharge was further reduced to 10%.

It violates the guidelines for dam operation, which requires that the amount of discharge be adjusted during the flood season to keep the water level below the flood limit.

Suddenly, a large amount of water flowed out and did not even provide proper guidance.

An emergency letter saying that the amount of discharge will be doubled was sent to the residents when the scheduled discharge time came.

Water Resources Corporation is only blamed on the weather.

[Lee Han-gu/Director of Water Resources Corporation: I have to say that we had to increase the amount of discharge compared to some unexpected rainfall, and that we considered the safety of the dam.] A

flood is visible in front of you. There is.
