New MSc graduation topic at Deltares
Topic: field measurements on scour by propeller jets
Background
Propeller jets can generate strong jets that influence structures such as quays or locks but can also
cause erosion of bed materials (scouring). In extreme case this can even cause a structure to fail.
Guidelines exist for protective measures. However, the influence of jets on their surroundings is far
from known fully, particularly in complex flow conditions and geometries. This includes confined areas
and propeller jets close to quay walls. In addition, with increasing sizes of vessels, also the sizes and
engine powers of bow thrusters and propellers have increased. This means that present guidelines
may be no longer be applicable.
Project description
In the summer of 2019 a field measurement campaign will conducted in the Port of Rotterdam
investigating propeller scour. The student will perform and analyse the field measurements in close
corporation with experts of Rijkswaterstaat, Port of Rotterdam and Deltares. This study aims to verify
design guidelines and to contribute to filling in the knowledge gaps that exist within this field. The
outcome of this study will be used to design guidelines and the student will be involved in
defining future research objectives.
Deltares is a leading, independent, Dutch-based research institute and specialist consultancy for
matters relating to water, subsurface and infrastructure. We apply our advanced expertise
worldwide, to help people live safely and sustainably in delta areas, coastal zones and river basins.
The objective of the Port of Rotterdam Authority is to enhance the port’s competitive position as a
logistics hub and world-class industrial complex. The core tasks of the Port Authority are to develop,
manage and exploit the port in a sustainable way and to deliver speedy and safe services for
shipping.
