Assesment of beach morphology at Dungun Coast / Ahmad Wahbi Abdul Majid

The coastal zone represents diverse and highly productive ecosystems, such as mangroves, coral reefs, aquatic grasses and sand dunes. Such habitats are under threat as a result of globalization, due to increased anthropogenic activities on the coast. These coastal ecosystems need to be protected in order to ensure sustainable development. The key erosion causes along the coast are primarily due to natural cycles or human activities. The increasing of the eustatic ocean level (SLR) is also a major concern, particularly in low-lying seaside nations and zones. This research is conducted to study the beach profile along the beach in order to produce a visualization of the beach. Just 12 per cent of the total Terengganu coastline is under severe erosion, according to extensively reported studies. Beach profile survey and interpolation technique was used to define and explain the difference in beach profile characteristics along the Dungun beach coastline. From this survey method, the net shore drift can be calculated dependent on the data observed. The result showed that there are two of Management Unit which is MU 1 and 5 that have been analysed as the lowest slope profile percentage with Average MU Slope percentage about 5.371% and 5.123%. Next, the infrastructure and coastal community that could be risky toward erosion too have been identified which is MU 1 and MU 5. To sum up this research work, the study findings could be useful in order to important decision-making to protect and mitigate steps toward sustainable coastal management along Dungun coastline.
