Three-dimensional refined modeling of water quality in Victoria Harbour

The three-dimensional water quality model has been developed to simulate the variations in water quality and the ecosystem in the harbour.The model is unique in that it completely integrates the refined modelling of the hydrodynamics, biochemical reactions and the ecosystem in the harbour.It is a 3-dimensional segmented model which is capable of resolving mean daily variations in all the parameters relevant to pollution control.It predicts daily fluctuations in the oxygen content at different depths in water throughout the year.It takes into account transport and settling of poVutant partities.It predicts light penetration from computed turbidity variations.It includes interactions between the ecosystem and water quality, through nutrient cycling and photosynthesis.The model has been calibrated well against the historical data set of water quality observations.
