| Abstract | A multi-layer model is required for detailed computation of cunents and water qualities in
the Gulf of Thailand.
A five-layer model is developed for the Gulf of Thailand under the assumptions of
incompressibility of water, uniform density and neglecting of vertical acceleration. Forces
considered include wind stress, tidal effects, coriolis force, convective acceleration, bottom
friction and shearing stresses at interfaces as well as mixing in horizontal directions. The
shearing stresses at interfaces of layers are important mechanism in transferring the stresses
from one layer to the others. The model is formulated by using the Alternating Direction
Implicit (ADI) finite difference numerical method. Forward time and centered space
(FTCS) linearization process is employed.
The model is applied to the Gulf of Thailand after proper model calibration. Water levels
and current velocities are computed. Velocity fields for different layers are plotted. Vertical
velocity profiles are obtained. Wind effects on tidal currents are discussed. These results are
reasonable when compared with the measured data. |
