The Vu Gia river ( vi, sông Vu Gia) is a river in
Đại Lộc district in the
province of Quảng Nam in central
Vietnam.

confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); o ...
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 disctrict, where it splits into the
Yên and the
Bình Phước.
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.
