| Abstract | In order to quantify the coastal morphology in the vicinity of Map Ta Phut port numerical
simulations are conducted for various incident wave conditions. The simulations of wave
breakerline, shoreline change morphology, nearshore wave and current fields are carried out by
four mathematical models. The mathematical models for simulating breakerline, wave and current
fields are based on recently developed time dependent mild slope equation. In the simulation of
wave field, the combined effects of wave reflection, refraction, diffraction and wave breaking in
the presence of coastal structure and complicated bottom topography are taken into consideration.
The numerical model (1-line) for predicting shoreline change morphology is based on sediment
mass conservation equation where cross-shore directed sediment transport rate is neglected. The
alongshore transport rates, the principal parameter of 1-line model, are estimated from the
breaking wave characteristics of breakerline model.
The computer programs written by Numano (1988) for the simulations of breakerline,
wave and current fields, are used as the basis of development. Numano's models are further
extended to handle both normal and obliquely progressing waves. A computer program (1-line
model) for predicting shoreline change is proposed. The applicability of the models is first judged
through simulations on hypothetical beach with constant slope. The scaling effect on the models
is then investigated by conducting simulations on a beach schematized and scaled from the Map
Ta Phut beach. Finally, the models are applied to the Map Ta Phut beach with field wave
conditions.
The obtained results draw the conclusion that a significant change in the coastal
morphology around the port is apprehended with gradual accretion of shoreline in the updrift side
of the western breakwater. |
