Resumen
- Kuala Terengganu, one of the coastal zones in Malaysia, is prone to natural hazard factors, such as coastal erosion which may affect the morphological condition of the beaches in Terengganu. The beach morphological changes were driven by the seasonal monsoon such as Northeast Monsoon (NEM) and Southwest Monsoon (SWM). Hence, to understand the short-temporal morphological response of meso-tidal beaches during spring tide events throughout the lunar cycle phase, the study was investigated in Batu Buruk Beach, Kuala Terengganu. The coastal profiles, particularly during spring tide (Full Moon and New Moon phases) were collected from five (5) transects starting on October 2020 to October 2021. The monitoring of cross-shore was conducted using Real time Kinematic (RTK) to measure the cross-sectional area and sediment volume changes. The data collected were computed using profiler 3.2XL software. MIKE-21 numerical modeling software was used to simulate tidal elevation within the period of this study. The results showed that Batu Buruk Beach received significant impact from the lunar cycle, especially on sediment gain and loss. The cross-sectional analysis revealed positive sediment gains during the Full Moon. However, during the New Moon phase, erosion seemed to take place around the upper swash zone area. This provides an insight into the spring tide erosion and accretion and contributes some understanding to beach recovery processes.
