| Abstract | The objective of this study is through the SPSS analysis of the TM image, to decide which bands are best for suspended sediment determination and to assess the technical feasibility of using TM and SPOT data with digital processing and GIS analysis to evaluate the general surf ace suspended sediment distribution of Chao Phraya Estuary in Gulf of Thailand. The TM seven bands through the Hierarchical Cluster, Factor, Correlation Analysis, found that the bands 2, 3 are good f or suspended sediment determination. An empirical Correlation Coefficient and Multiple Linear Regression analysis approaches of relating TM data with "sea truth" data, highly significant relationship was identified between them. A simple model yb = a + b*x for between suspended sediment concentrations, and resulting after transformed in Y = A + B*X, was found to best typify the data (linear regression). Supervised classification and linear regression model were used to identify suspended sediment distribution and in turn, to u se GIS analysis as a tool to formulate multitemporal maps for monitoring the suspended sediment movement and river bank change. The findings are that the suspended sediment discharge from the Chao Phraya River was decreased. The suspended sediment mainly was from the river bank erosion and transports to far the seaward. The severe bank erosion because the decrease of the silt from the river. The GIS map integrated with bathymetry provide a high spatial resolution data base useful in investigating river plume transport. |
