Cees van Rhee
Since 1985, Cees has been engaged with research for the dredging industry. The first five years were at WL|Delft Hydraulics (presently Deltares) and then at Van Oord, a dredging contractor where he was employed at the various departments and projects, from 1990 to 2011. At the end of 2002, the author obtained his PhD degree. Since October 2007, he is professor Dredging Engineering at Delft University of Technology. His main scientific achievements are modelling of highly concentrated sediment water flows and high velocity erosion of granular sediments.

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.
Cables for offshore wind farms in the North Sea are buried for protection. A highly variable seabed topography influences the trenching process in sandy soils. A model has been developed to estimate the influence of sand dunes on the trenching process.
Modelling the effect of water depth on rock cutting processes with the use of discrete element method
Efficient rock cutting is still a challenge in the dredging industry. A new method that takes into account the effect of water depth could refine rock cutting processes.
The IADC Young Author Award-winning paper verifies the agreement between the theoretical calculations for a new toothless draghead and the real situation when the draghead is being used.
For production, sand quality and environmental reasons predicting the amount of the so-called overflow losses when using a trailing suction hopper dredger is very important.
