| Summary: | The present study on the beach morphology and its profile dynamics along the selected beach of Pahang comprising the areas from Teluk Chempedak to Kuala Pahang. Beach stations were monitored monthly for a complete 1-year cycle; beginning from February 2012 to February 2013 at 12 corresponding stations established at random morphological intervals. The aim of the study is to determine the morphological development of the respective beach based on profile alteration, including the erosional and depositional rates and other ambient littoral morphodynamic factors including sediment grain-size analysis. Topographic beach profiles were surveyed using an electronic theodolite in order to attain composite height, distance, and slope of the beach. Analysis on the beach process activity was extended for numerical modelling simulation in order to understand the physical processes involved. Analysis of beach profile changes revealed that minor changes at dune and high-tide zone with a negligible rate of either erosion or deposition for most stations. The northeast monsoon activity has transported the sediment away from the stations causing most stations experienced erosion. However, the process of deposition took place at most stations that could be noticed at the mid-tide level and some extent of low-tide areas throughout the post-northeast monsoon season. The beach slopes were ranged from 0.98° to 6.26° and indicates most beaches have a gentle slope with lower degree value. The quartz sand was found along the study area with domination of fine grain sediment with medium and coarse fractions obtained at certain sites. Model simulation implied that the selected domains are classified as transported area, which having more tendencies to become eroded if any disturbance introduced such as development to the area without proper design and planning. Periodically, changes in currents, tides and wave action, however, produced a normal cycle if the virginity of the beach remains unchanged. The necessity of understanding of these factors is high as to maintain the sustainability for both natural and human systems. |
