Vu Gia River

The Vu Gia River (Vietnamese: sông Vu Gia) is a river in Đại Lộc district in the province of Quảng Nam in central Vietnam. It is formed by the confluence of the Bung and the Cái in Đại Sơn commune in the west of Đại Lộc district. It flows through the length of the district until the boundary with Điện Bàn district, where it splits into the Yên and the Bình Phước. After the Quảng Huế River branches off, the river is commonly called Ái Nghĩa River (Vietnamese: sông Ái Nghĩa). The Vu Gia is part of the Vu Gia–Thu Bồn river basin, and the Vu Gia and the Thu Bồn seasonally undergo exchange of flow.

Before 2000, most of the flow of the Vu Gia River went, through a multitude of different channels, into the Hàn river in Đà Nẵng, where it is an important source of freshwater. A large flood in 2000 created the "New Quảng Huế" distributary, which allowed most of the flow of the Vu Gia to flow into the Thu Bồn during the dry season. This new channel had to be dammed to restore the original flow. The flow between the Vu Gia and the Thu Bồn is important for the livelihoods of many people downstream in Quảng Nam province and Đà Nẵng city. Regulating this flow therefore remains a concern for the local authorities.
