Programme Highlight

The existing Kai Tak Nullah serves as a main drainage channel in the Kowloon east area. It originates from the Po Kong Village Road at Wong Tai Sin, flows along the Choi Hung Road, runs underneath the Prince Edward Road East, traverses the Kai Tak Development area and finally reaches the Victoria Harbour. Its drainage capacity is inadequate to meet the current flood protection standard and the areas in the vicinity of the nullah in Wong Tai Sin are susceptible to flooding during heavy rainstorms.  To reduce the flooding risk of these areas, the Drainage Services Department (DSD) commenced the drainage improvements works for the nullah at Wong Tai Sin in October 2011 with the target completion date of end of 2017.  In addition to uplifting the drainage capacity of the nullah, DSD strived to revitalize the Kai Tak Nullah into an attractive green river corridor through the urban areas, namely Kai Tak River, by introducing the concept of blue-green infrastructures. The project comprises the construction of a 400m long single-cell box culvert under the heavily trafficked Choi Hung Road, nullah deepening, utilities diversion and landscaping works.

The seminar will cover the challenges encountered during the construction and the revitalization of Kai Tak River as a green river corridor.  The major challenge of this project is to maintain the hydraulic performance of the river during the construction period as the reconstruction works are all carried out inside the river.  Particular consideration has been given to the construction methods and sequences for upholding the flood protection standard.  Furthermore, design considerations for improving the hydraulic performance of the river by engaging a physical hydraulic scaled model will be discussed.


Speakers will also present the design concept behind revitalizing Kai Tak River into a green river corridor in urban area with aesthetic, greening, landscaping and ecological elements for public enjoyment.
