Abstract: In the past few decades, Singapore has been perpetually reclaiming its land to meet the growing demands of its industrial and port operations. In order to properly manage the coastal activities, knowledge of the local sediment transport and morphological characteristics in Singapore Strait is important. Numerical modeling tools have been greatly utilized in this aspect to enhance the understanding of local sediment transport and morphological response to different scenarios at high spatial resolution. However, due to its geographical location, hydrodynamics in Singapore Strait is complicated by the convergence of the Indian Ocean and South China Sea. Previous studies show the throughflow in the narrow strait is not induced locally, but rather caused by wind and pressure forcing applied on the two large basin scale water bodies. Throughflow in Singapore Strait has been found to vary seasonally with bi-annually flow reversals. In order to account for this seasonal throughflow in a localized model of high spatial resolution, the multi-scale modeling (i.e. nesting) approach is applied. Based on the hydrodynamics simulated using multi-scale modeling, this paper will study the effect of seasonal throughflow on the sediment transport and morphology in Singapore Strait. Results of this study will also provide insights into the local sediment transport characteristics during different time of the year.
