Goal and objectives of the project
  • Determine of levels and cause of various sediment flux from the Red River system to the coastal zones during last 100-year.
  • Asessment impact of the sediment flux variation from the Red River System on the Red River Delta coastal zones.
  • Propose some solutions to cope with disvatage impact the sediment flux variation on the Red River Delta coastal area
Main results

Theoretical results:
(1)-Variation of Sediment Discharge of the Red River System during last 100-year:
Based on the approach “source-to-sink” combined with some main methods such as 210Pb and 137Cs radionuclides, X-ray diffraction, laser, and numerical model for studying of clay mineralogy, datings, sedimentation rates in the subaqueous Red River Delta. Annual water and suspended sediment across the nine months of the delta (1960-2010) was simulated using the MIKE11 numerical model (figure 4). In recent 100 years, contents variation of the illite, smectite and smectite/(illite+chlorite) indicated that variation of sediment flux of the Red River system could be divided by four periods: slightly increased during 1910-1930, slightly decreased from 1930 to 1960; moderately decreased between 1960 and 1990, and strongly decrease since 1990 to present.
(2)- The sediment flux variation from the Red River System influnced on distrubution of sediment surface and suspended sediment transport, decreased delta evolution, coastline and channels changged, and some estuarine escosystems.
Applied results:
The project given some solutions in oder to response with negative impact: management, engineering, no-engineering, setbackline for cope with variation of sediment discharge of Red River System.
