Geography
editThe Dong Nai River flows through the provinces of Lam Dong, Dak Nong, Binh Phuoc, Dong Nai, Binh Duong and Ho Chi Minh City with a length of over 437 km and a basin of 38,600 km2, if calculated from the source of the Đa Dâng River, it is 586 km long. From the confluence with the Đa Nhim River below the Pongour waterfall, it measures 487 km. The Dong Nai River flows into the East Sea in Cần Giờ District.
The main stream of upper Dong Nai river is also known as the Đa Đang river: the name used by the minority Maa and Koho people. The river originates from Lam Vien plateau, meandering along the northeast-southwest direction from the mountains to the plateau in Ta Lai (Tan Phu district, Dong Nai province). The river forms the natural boundary between Đăk R'Lấp District (Dak Nong) and Bảo Lâm District, Lâm Đồng Province, Cát Tiên District, between Cát Tiên and Bù Đăng District, Tan Phu District, Dong Nai and between Tan Phu and Đạ Tẻh District.
After meeting the Bé River, the Dong Nai River forms a natural boundary between Dong Nai on the east and Bình Dương Province on the west bank.
Between the confluence with the Saigon River and where it splits into the Soài Rạp and Lòng Tàu distributaries, the river is commonly known as the Nhà Bè river.[2]
The river flows through Bien Hoa City, then flows along the boundary between Dong Nai and Ho Chi Minh City, between Ba Ria - Vung Tau and Ho Chi Minh City.
