Abstract: The flows in Malacca Strait and Singapore waters are the result of complex tidal interactions of the Indian and Pacific Oceans, monsoon effects and further atmospheric forcing. For modelling the tidal flow, the authors use the Singapore Regional Model (SRM). This paper investigates the potential improvement of SRM's water level and flow predictions by domain decomposition (DD) with selective grid refinement, inclusion of internal tide generating forces and applying weather forcing at different scales. The DD model results are shown to be more accurate than the original SRM results for tidal predictions within the region of interest. The separate and combined effect of weather and tide are studied using the SRM and a model that covers a much larger domain. The results show that non-tidal flows in the Singapore vicinity during the North East monsoon period are generated in the South China Sea, and can only be properly modelled by a model that includes that whole basin.
