Beach profile changes are subjected to various parameters such as tides, currents and wave effect. This study investigates the beach profile changes at Teluk Gorek Beach, Mersing and to evaluate the effect of soil density on beach sediment. A total of seven beach profile cross- sections with offset of 20 m apart were established to monitor the presence of erosion and accretion. The monitoring work was done on January and March 2016 during spring tide. The estimation of erosion and accretion were performed by comparing the profile obtained on January and March. The result shows that the beach profiles have experienced both erosion and accretion during the period of study. The soil density change varies to the erosion and accretion process. As a conclusion, the beach is slightly changes during the period of study. The density increase for erosion process while decrease when accretion takes place.
