APPLYING SATELLITE IMAGES TO DETERMINE SUSPENDED SEDIMENTS CONCENTRATION IN THE SOUTH COASTAL ESTUARIES AREA OF VIET NAM

Abstract

Estimation of suspended sediment concentration is an important issue in water quality assessment research, environment of the south coastal estuaries area and assessing shoreline morphology. This paper have used satellite images to specify the relationship between the reflection spectrum of satellite images and suspended sediment concentrations in Me Kong estuaries and the south coastal of Viet Nam which based on the method of combining field observation data and qualitative satellite images Analysis. The results of the study which has created a complete picture of the trend of sediment transport in Me Kong estuaries and the south coastal of Viet Nam showed the correlation between the reflected spectrum from the satellite image (Modis) and the suspended sediment concentration is an exponential relation (R² = 0.82).
