Abstract: SLON (Sigma Layers Offing Numerics) model is being developed in TMSI, NUS as the further evolution of the numerical model THREETOX developed in IMMSP, Kiev, Ukraine. It is a multidisciplinary model including hydrodynamics, water quality and suspended sediments simulations. Hydrodynamics of SLON is governed by 3-D free-surface hydrostatic equations. Implemented numerical algorithms ensure effective modeling of salinity and temperature fields in coastal regions with complex bottom topography; in particular, with artificial ship channels, underwater walls and other man-made constructions. Low-cost parallelization is realized in SLON via horizontal domain decomposition and using MPI (Message Passing Interface) for a dynamic data exchange. At present the model is applied as a research and forecast tool to Johor Strait and Singapore Strait modeling.
