Visual plumes coastal dispersion modeling in south-west Sabah

The model used for coastal dispersion modeling was the US EPA Visual Plumes model encompassing the DKHW (Davis, Kannberg, Hirst model for Windows) and Update Merge (UM3) sub-models. In theory, the dilution capacity of open waters, particularly coastal areas, straits and oceans are close to being inf...
