FACULTY/DEPARTMENT: Faculty of Civil Engineering and Geosciences

JOB TYPE: PhD

SCIENTIFIC FIELD: Engineering

HOURS PER WEEK: 32-40

SALARY: € 2.541,00 – € 3.247,00

DESIRED LEVEL OF EDUCATION: University graduate

VACANCY NUMBER: TUD02783

Are you passionate about coastal seas and oceanography? Do you have the drive and curiosity to study flow and transport processes under present and future conditions? Then this job may be for you!

Job description

For the research project ‘Circulation, mixing and transport in the southern North Sea and the influence of large scale sand extraction’, the section of Environmental Fluid Mechanics at Delft University of Technology is looking for a candidate with a strong background in physical oceanography/ environmental fluid dynamics and/or 3D hydrodynamic modelling, or a physicist, mathematician or engineer, strongly motivated to study flow and transport in a coastal sea.

In this project, you will investigate the physical oceanography of the southern North Sea, with a particular focus on the Rhine River Plume, one of the largest river plumes in Europe. Coastal processes such as tidal straining, river plume dynamics, upwelling and downwelling and sub-mesoscale processes determine the circulation, mixing and transport of fine sediments, tracers and larvae in coastal and shelf seas. You will study how these phenomena will be affected by bathymetric changes related to large scale sand extraction, both now and under predicted climate change. You will also explore how these effects influence the transport of fish larvae across the southern North Sea and into the deltas.

To investigate these coastal transport processes in the southern North Sea, you will use a combination of  modelling, particle tracking and data analysis. High-resolution 3D numerical hydrodynamic modelling of the North Sea will be the main research method. Existing and new field data of salinity, temperature, velocity and turbulence will be collected for physical understanding and model verification. The simulations will be carried out on high performance computational facilities for a range of sand extraction designs, also considering IPCC climate scenarios. Advanced Particle Tracking techniques will be applied to determine the impact on larvae transport and the connectivity between spawning grounds and settling locations. You will be supervised by Prof. Dr. Julie Pietrzak and Dr. Ir. Wouter Kranenburg, and will actively collaborate with a wider group of researchers.

This project is part of the collaborative, multi-disciplinary NWO-funded research program OR ELSE. In this program, a broad consortium of Dutch institutes, universities and stakeholders will work together to develop recommendations on sustainable, ecosystem-based sand extraction strategies for the southern North Sea. As part of this, new fundamental knowledge will be developed on the effects of large-scale sand extraction on the physical, biogeochemical and ecological conditions of ecosystems. In this PhD-project on circulation, mixing, turbidity and larvae transport, you will collaborate with other PhD’s in the OR-ELSE program who will be carrying out research on e.g. bed evolution, algae production, seafloor fauna and shrimp and fish populations. The program is motivated by an expected dramatic increase in sand extraction due to climate change, to supply sand for large scale sand nourishments for coastal protection both in The Netherlands and around the world.

We are looking for a candidate with curiosity, motivation, a relevant background and an eagerness to learn. If you are interested in this position, please explain your motivation in your application letter. Discuss what interests you in this particular project and how your background and experience relate to it. We also welcome your application if your experience does not fully fit our advert, but please also explain what captured your imagination.

Requirements

  • An MSc degree, preferably in Physical Oceanography, Environmental Fluid Mechanics, Earth System Science, Meteorology, or Physics, Mathematics, Hydraulic Engineering or other relevant disciplines.
  • Strong proven affinity with physical processes behind circulation and transport, preferably related to transport hydrodynamics in estuaries, river plumes, coastal seas or oceans.
  • Strong affinity with numerical modelling and/or data processing, preferably related to circulation and transport in oceans, coastal seas, river plumes or estuaries.
  • Excellent ability to think conceptually and quantitatively.
  • Excellent ability to communicate in English both in speech and in writing.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.

Conditions of employment

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.
