Various risk-based methods are used to assess environmental impacts from dredging and dredged material management activities.
Is it possible for an in-site disposal area to be environmentally and economically preferable to an offshore disposal site? Real-time monitoring says yes, there are numerous benefits to the disposal of dredged material in-site.
A state-of-the-art 3D plume model, used at the Ras Laffan Port Expansion project, simulates alternative disposal scenarios and helps develop Safe Disposal Maps.
This study analysing changes in the bottom-topography at dredged material disposal sites and the interaction between disposed matter and the surrounding density currents received the IADC Award at the CEDA Dredging Days.
To encourage the beneficial use of dredged material, a harmonised approach – especially for land disposal – is urgently needed.
