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.

Losses of Fill

Losses of fill can occur for several reasons and can result in not meeting the quantity of fill required for the dredging operation.

An Analytical Approach to the Sedimentation Process in Trailing Suction Hopper Dredgers

A number of theories are used (Camp, Groot, Miedema and Vlasblom, Yagi, Braaksma, Ooijens and van Rhee) to determine the overflow losses when loading trailing suction hopper dredgers. The model derived here has several important improvements, including the speed of doing the calculations.

A Computationally Efficient Model for Predicting Overflow Mixture Density in a Hopper Dredger

Creating accurate models for the prediction of overflow losses by trailing suction hopper dredgers is an invaluable tool in determining the feasibility of land reclamation.

Adding Dynamics to the Camp Model for the Calculation of Overflow Losses

An IADC "Most Promising Student" Award has been presented to a graduate of TU Delft for his thesis which describes the dynamics of hopper loading both in simulation and as compared with actual measurements onboard a TSHD.
