Transformation from River Channelisation to River Revitalisation
River channelisation is a conventional approach of resolving flooding problem in view of its outstanding hydraulic performance.Such design,however,has a negative impact on the city landscape and also leads to degradation in the ecology and subsequent decline in ecological habitats and overall biodiversity.With a vision of providing sustainable drainage services and pursuing a higher standard in environmental and ecological preservation,the Drainage Services Department(DSD)of the Government of the Hong Kong Special Administrative Region has incorporated environmentally friendly design in its drainage improvement projects in Ho Chung River,Upper Lam Tsuen River and Kai Tak River.Indeed,incorporation of environmentally friendly drainage design in a densely developed area like Hong Kong is a great challenge.In this paper,the improvement of ecology,enhancement of biodiversity and the characterised features of the abovementioned rivers achieved in the drainage improvement projects will be discussed.Looking ahead,by adopting the concept of manifesting and revitalising water bodies into drainage improvement works and development of new development areas,the community will be further benefited from the improved environment.In the revitalisation of Tsui Ping River at Kwun Tong as well as the drainage planning of new development areas,DSD will adopt new standards in the planning and construction of drainage facilities with a view to providing a better environment for the public.
