| Abstract | The Gulf of Thailand is the most important beach resource of Thailand. Normally the
large and heavy industrial factory grew up in the area around the deep-sea ports. Rising of
pollutants becomes serious in this region. To understand the characteristic of the water body
and the dispersion process of the water quality is very interesting. A Multi-Layer Model of
Water Quality is one from many choices to describe the water quality characteristic. This
tlu·ee-dimensional model for estuaries and coastal seas, developed by Liu and Nelson (1977),
is employed to express the salinity, temperature and density distributions over the Gulf of
Thailand. The significant factors to perform the model are initial condition, boundary
condition and dispersion coefficients. The initial condition is applied for saving computational
time because of the dispersion process is slow process compare with the large area such as the
Gulf of Thailand. The boundary condition is performed to control the water quality near the
shoreline and the open sea. The vertical distributions of salinity, temperature and density are
assigned tlu·ough this 3-D model. The last factors, which are dispersion coefficients, are
represented the dispersion characteristic in this area. The results are calibrated with the
observed data over the dry period (March-April 1982-1993). At the first 3 layers the computed
salinity, temperature and density are conformed to the general pattern of observed data
especially to the boundary conditions. There are some different for the deepest layer due to the
other unknowns factor influence to the flow. |
