We are excited to share that in2Dredging Pty Ltd (i2D) will be participating in the Australasian Coasts & Ports 2025 Conference being held in Adelaide from 18 to 21 August 2025. This biennial conference gathers coastal and port professionals from across the region to share innovations and research shaping the future of our marine environments. As part of the programme, i2D will present insights into the sustainable dredging practice of Water Injection Dredging (WID).
Presenting Our Work on Water Injection Dredging
This year, Dredging Engineer, Shameeka Nanayakkara and Principal Dredging Engineer, Simon Burgmans will represent i2D. In collaboration with David Habib from Port of Melbourne, Shameeka will present a technical paper titled “Water Injection Dredging: Advancing Environmentally Sustainable Dredging Practices in Australia.”
The presentation outlines the successful application of Water Injection Dredging (WID) at the Port of Melbourne. It showcases WID’s potential to achieve efficient sediment clearance while significantly reducing environmental impacts. The study combines predictive modelling using i2D’s in house tools, Sub Sea Soil Jetting (SSJ) and Estimator for WID (E4WID). Field trials support the models of these tools and validate WID’s operational feasibility and performance.
How WID Works: Gentle Yet Powerful Sediment Relocation
WID is an innovative, low-impact dredging method that injects water into sediment beds forming a highly diluted, slurrified and mobile turbidity cloud. This cloud is so light that baroclinic pressure gradients, caused by subtle density differences, overcome the sediment mixture’s yield stress. As a result, the sediment flows unassisted along the riverbed, often travelling for kilometres, under the influence of gravity.
The WID methodology not only enhances sediment relocation efficiency but also minimises surface disturbance. It is particularly well-suited for use in environmentally sensitive areas with naturally high sediment loads.
Driving Innovation in Dredging
As a dredging engineer at i2D, Shameeka has contributed to a broad range of dredging projects across Australia and internationally. Through this work, she has gained experience in providing both technical and operational support for capital and maintenance dredging projects. Shameeka’s work reflects a strong commitment to innovative, effective, adaptive and sustainable dredging practices tailored to Australia’s unique port environments.
See you in Adelaide!
We are proud to be part of the conversation on sustainable dredging. And we look forward to connecting with fellow professionals at Australasian Coasts & Ports 2025. Join us as we exchange insights and collaborate with others committed to environmentally responsible coastal and port developments.
