Topic Overview:
In this lecture, RILS scholars will introduce recent innovations in land creation, including land reclamation and floating solutions. A research team in RILS of PolyU has proposed and demonstrated PolyU’s sustainable reclamation approach using waste dredged sediments plus other inert wastes as fill materials and a combined method for fast improvement of dredged hydraulicly filled slurry and existing soft soils in seabed. Large-size physical model tests, prototype field test, and computer modelling have been conducted and proved that PolyU’s approach and method are feasible, effective, and economical. The unit cost of using dredged sediments as a fill material is only one eighth of using manufactured sand as fill material. Billions of dollars and a lot of construction time can be saved for large-scale marine reclamation in Hong Kong.
The lecture will also examine the potential of floating solutions for sustainable megacity development, renewable energy generation and establishing a blue economy. By exploring these innovative solutions, we aim to promote a more sustainable and resilient approach to land creation, with far-reaching benefits for coastal communities and the environment.
