Abstract

This chapter presented the general characteristics of the Hong Kong coastal environments and the potential impacts associated with large-scale developments. The approach for water quality model validation and application of the validated models for prediction of water quality changes in reclamation, bridge construction and export of effluent projects are briefly described.

Dredging and filling activities are of major concern in the reclamation and bridge construction projects. Examples have been given of the increase in suspended solids in fish culture zones and oyster beds in Deep Bay. Export of effluent from sewage treatment works to less sensitive water bodies on one hand reduces the eutrophication in the originally affected water body but on the other hand introduces additional loads into the receiving water body. Through the application of water quality modelling, the potential impacts and benefits of the project can be examined providing accurate data for decision making on the feasibility of the development projects.
