Overflowing rivers cause flooding in low-lying areas of Da Nang
By 10 a.m. on Tuesday, due to heavy rainfall, the Cu De River reached flooding stage while the Tuy Loan River is prone to jump its banks, and the Cam Le River overflowed its banks, sending a large amount of water to flood a low-lying section of Thang Long Street in Cam Le District.
Meanwhile, reservoirs of Song Bung 4 and Dak Mi 4 hydropower plants are discharging water into the downstream of the Vu Gia River. Hydropower plants have increased water release from their reservoirs into the downstream of the Vu Gia River in order to make sure that water levels are lowest at their reservoirs in an effort to cope with heavy rains which could trigger flooding in the downstream areas of Vu Gia and Thu Bon rivers
