According to the National Center for Hydrometeorological Forecasts, floods in the Vu Gia River (Quang Nam) are increasing very rapidly. The water level at 16 o’clock on the Vu Gia River in Ai Nghia is 7.75 m, 0.25 m below the 2nd Ranger.
According to the announcement of Dak Mi Hydropower Joint Stock Company, it is expected that at 15:30, the Dak Mi 4 hydroelectric reservoir will start to increase the discharge of the second flood, the expected discharge flow is up to 11,400m.3/ s.
Currently, hydropower Dak Mi 4 is discharging downstream of 5,100m3/ S. In the event that hydropower continues to maintain the current discharge level downstream in the next 6-12 hours, the water level in the Vu Gia river at Ai Nghia station is likely to rise to 10.3 m, at the 3rd station: 1.3 m (below the historical flood level in 2009 was 0.47 m).
In the case of the downstream Dak Mi 4 hydropower discharge as planned, 11,400m3/ s, in the next 6-12 hours, the water level in the Vu Gia river at Ai Nghia station is likely to rise to 11.2 m, at the 3rd station: 2.2 m (exceeding the historical level of flood in 2009 is 0.43 m).
The risk is very high and causes deep flooding, large low areas and landslides in the districts: Nam Giang, Dai Loc, Dien Ban, Duy Xuyen, Hoi An City (Quang Nam), Da Nang City.
