Track: Modeling and Simulation

Abstract

In this paper, A new formula of longshore sediment transport rate was developed based on phenomena of fluid movement through the sediment particle. The amount of fluid that penetrates the sediment particles with high permeability more than the sediment particles with low permeability. This formula is applied to identify shoreline erosion around of runway platform of Sultan Mahmud Airport, Kuala Terengganu. The shoreline changes model is solved by using finite difference method. Based on the simulation result by using this method, shoreline profile around this airport occur erosion. This erosion occurs on the south side of this airport. The average erosion in this area during 2 years and 3 years are 24.88m and 33.90m. In addition, the average erosion becomes worst when the simulation was done for 4 years that is equal to 42.93m. It is required an effective coastal management and coastal protection in order to minimize this erosion in the future.
