“…The modern Red River, which originates in the mountains of Yunnan Province, China, and flows about 1200 km from southeast Tibet to the South China Sea, is one of the major continental discontinuities in Southeast Asia (Milliman et al, 1995). The total sediment and water discharge of the Red River is 100e130 million t/yr and 120 km 3 /yr (Milliman et al, 1995;Pruszak et al, 2002), respectively, and drains an area of 160 Â 10 3 km 2 (Tanabe et al, 2006). Detrital zircon ages from Red River suggest that the southern Yangtze Block, which prior to these tectonic regions, is an important source of detritus Hoang et al, 2009).…”

“…Before HBD impoundment, the Red River suspended sediment flux was estimated to be 100-160 × 10 6 t yr −1 at Son Tay (Milliman et al, 1995;Pruszak et al, 2002), corresponding to a specific sediment delivery of 700 to 1100 t km −2 yr −1 , as compared to a global average of 120 t km −2 yr −1 (Achite and Ouillon, 2007). At 160 × 10 6 t yr −1 , the Red River was ranked as the ninth river in terms of sediment flux by Milliman and Meade (1983).…”

Abstract. The Hoa Binh dam (HBD), located on a tributary of the Red River in Vietnam, has a capacity of 9.45 × 10 9 m 3 and was commissioned in December 1988. Although it is important for flood prevention, electricity production and irrigation in northern Vietnam, the Hoa Binh dam has also highly influenced the suspended sediment distribution in the lower Red River basin, in the delta and in the coastal zone. Its impact was analysed from a 50-year data set of water discharge and suspended sediment concentration , and the distribution of water and sediment across the nine mouths of the delta was simulated using the MIKE11 numerical model before and after the dam settlement. Although water discharge at the delta inlet decreased by only 9 %, the yearly suspended sediment flux dropped, on average, by 61 % at Son Tay near Hanoi (from 119 to 46 × 10 6 t yr −1 ). Along the coast, reduced sedimentation rates are coincident with the lower sediment delivery observed since the impoundment of the Hoa Binh dam. Water regulation has led to decreased water discharge in the wet season (−14 % in the Red River at Son Tay) and increased water discharge in the dry season (+12 % at the same station). The ratios of water and suspended sediment flows, as compared to the total flows in the nine mouths, increased in the northern and southern estuaries and decreased in the central, main Ba Lat mouth. The increasing volume of dredged sediments in the Haiphong harbour is evidence of the silting up of the northern estuary of Cam-Bach Dang. The effect of tidal pumping on enhanced flow occurring in the dry season and resulting from changed water regulation is discussed as a possible cause of the enhanced siltation of the estuary after Hoa Binh dam impoundment.

“…4). The total sediment and water discharge of the Red River is 100-130 million t/yr and 120 km 3 /yr (Milliman et al, 1995;Pruszak et al, 2002), respectively, and the average sediment concentration in the river is 1.08 kg/m 3 (Tanabe et al, 2006). The Red River catchment now is composed of different geological blocks (Fig.…”
