Laboratory study on the efficiency of water injection dredging: An analysis on the influence of different dredge settings on the density current and production rate

The Port of Rotterdam experiences large amounts of siltation from the upstream rivers in its basins and canals every year. Furthermore, container vessels increase in size every decade and therefore require a larger navigational depth. These two factors cause the yearly amount of dredged material to increase. Currently, mainly trailing suction...

Experiments and 3D CFD simulations of Deep-Sea Mining plume dispersion and seabed interactions

Growing markets for sustainable technologies such as solar panels, wind turbines, and electric cars require an enormous amount of raw materials that might not be available from sources on land. Exploitation of seafloor mineral resources could secure the supply of raw materials for the future. However, proposed deep-sea mining (DSM) systems will...

Modelling far-field dredge plume dispersion

By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...

"2D or not 2D?" Three-dimensional effects in two-dimensional modelling of oscillatory flow in shelf seas and estuaries

This study develops a theoretical framework to judge in which particular instances a two-dimensional depth-averaged model is sufficient to simulate flow processes in continental shelf seas or when a fully three-dimensional model is required for accurate results. A depth-averaged model does not give any vertical information, which is unfortunate...

Data poor environments: Uncertainty propagation in hydrodynamic modelling

The objective of this study is to propose a method that is able to deal with data poor environments within coastal studies. Numerical models are useful tools to get insight in the coastal processes of the system being modelled. Inaccurate or poor input data leads to inaccurate or even incorrect model results. By stochastic modelling insight is...

Effectiveness of Silt Screens

Dredging and reclamation works are known to generate significant amounts of turbidity. In most coastal zones around the world, the resulting clouds of suspended fine sediment bring along environmental risks. Dredging contractors take mitigating measures to prevent free spreading of turbidity, which is usually also demanded by their clients and...
