Rivers, Ports, Waterways and Dredging Engineering

The research group Rivers, Ports, Waterways and Dredging Engineering is a fusion of three former research groups, namely River Engineering, Ports & Waterways and Dredging Engineering. While these former research groups have some overlap between them they concentrate on whole different subjects. As a result each of the former research groups has its own professor. For River Engineering this is Prof. dr. ir. W.S.J. Uijttewaal, while Ports & Waterways is under supervision of Prof. ir. T. Vellinga and Prof. C. van Rhee is responsible for the section Dredging Works.

River Engineering is all about the prediction of short- and long-term responses of river systems to natural and anthropogenic changes. Furthermore, it focuses on design measures to counteract negative trends. This section studies and teaches measures to enhance the different functions of a river, as well as methods to assess the near-field and far-field effects of these measures, on a short term and in the long run. The section has a strong foundation in the principles of fluid mechanics and sediment transport.

The section Ports & Waterways focuses on the design of ports and waterways. It involves expertise in the field of transport-economics, shipping, nautical matters, safety and logistics. It also involves knowledge of waves and currents, sediment transport and morphology, dredging and land reclamation, design of breakwaters, quays, bank protections and locks. Large port expansion projects, such as Maasvlakte II in the Netherlands, and projects to increase the capacity of access routes, such as the Panama Canal, are among the many challenging projects for port engineers and IWT engineers (IWT =  Inland Water Transport).

The subject of Dredging Works has very multidisciplinary interest. Therefore, the subject of dredging is being teached in the master Hydraulic Engineering as well as in the master Offshore Engineering. Dredging Engineering is about the displacement of large volumes of sediment. Large land reclamation projects, as the new airports in Hong Kong and Singapore, the large land reclamations for ports and industry in Singapore and the spectacular projects in Dubai like the Palm Islands (see picture) and “the World”, are examples of dredging works. All Dredging processes involve slurry flows and are dominated by erosion, transport and sedimentation under special hydraulic conditions.
