Originating in Yunnan, China, it flows through Northern Vietnam and empties into the Gulf of Tonkin. In Vietnam, the Red River has a length of 510 km, playing a crucial role in the cultural heritage of Vietnamese rice cultivation.
The Red River boasts a substantial average annual water flow of 2,640 m³/s (at the river mouth), with a total volume of water reaching 83.5 billion m³. However, the distribution of water flow is uneven, dropping to about 700 m³/s during the dry season but surging to as much as 30,000 m³/s during the peak of the rainy season.
2. Where does the Red River (Sông Hồng) originate from?

1. The Vital Role of the Red River in Daily Life and Production
The Red River significantly contributes to agricultural richness, with its silt enhancing fertility and expanding coastal areas in Thai Binh and Nam Dinh provinces. The sediment from the river also supports the cultivation of freshwater fish in the Northern Delta. Furthermore, the river serves as a crucial irrigation source for the Red River Delta and plays a key role in water transport, facilitating the movement of goods from north to south through various waterway junctions.
The Red River is a relatively abundant source of hydropower, enabling the efficient exploitation of hydroelectric energy through large plants such as Hoa Binh, Son La, Lai Chau, Huoi Quang, Tuyen Quang, Chiem Hoa, and Thac Ba.
