coast zones if a suitable parameterization is well done. In

this case after a particle is released, it quickly moves

downward to the layer close to bottom and its travel

length becomes shorter. Sometimes, it settles on bed de-

pending on the strength flow velocity. In this situation

movement of particle is quite similar to that of bed-load

transport.

Finally, Langrangian particle tracking model can be

one of the prospective approaches for further applications

in future when the ability of memory and speed of com-

putation of PC are not the real issues.

This study was funded by NAFOSTED. The authors

would like to thank Dr. Baharim from UTM for the

measured data on velocity at the station STN4 and the

harmonic constants of Sungai Segget. At the same the

first author also would like to express his deep gratitude

to Mr. Craig for many things he did. Many thanks are

sent to Mr. Scandrett for his useful help.
