Can surface turbidity plume generation near a Trailing Suction Hopper Dredger be predicted?

A surface plume from overflow can stay suspended for long periods and distances, resulting in negative environmental impact through increased turbidity and sedimentation. Generation of a surface turbidity plume from the overflow of a Trailing Suction Hopper Dredger is investigated by a process-based, detailed Computational Fluid Dynamics model.

To assess the environmental benefits of an “idyllic” world without dredging, the impacts of dredging activities are compared to the impacts of other human and natural sources of sediment plumes.

There are two types of driving force that urge us to assess the effects of dredge-generated plumes, a genuine concern for the environment and the regulations that forbid us to dredge unless we can demonstrate that harm will not be caused to the environment.
