Malaysia is known for its coastal resources and these areas are often used as socioeconomic
developments. However, these activities give effects such as coastal erosion.
There are many factors related to coastal erosion, so the objective of this study is to
investigate the most influence risks factor to coastal erosion problems. We have used
Decision-making Trial and Evaluation Laboratory (DEMATEL) method to solve this
problem. It is because its ability to gathers collective information to capture the causal
relationship between potential criteria and visualize them into diagraphs. We have
identified four dimensions and fourteen criteria as critical factors contributing to the
erosion. Then, we obtained that shoreline changes and relative sea level rise are net
causes while wave condition is the most influence risks factor to coastal erosion problems.
Last but not least, hopefully this research could be beneficial to others.
