PhD on Fundamental understanding of mitigation measures in salt intrusions

PhD on Fundamental understanding of mitigation measures in salt intrusions

Applied Physics


Saltwater intrusion in estuaries is characterized by the flow of a wedge-shaped layer of seawater, a ‘salt wedge’, along the bottom as a result of differences in densities between fresh and salt water. In the face of climate change, saltwater intrusion is an increasing problem for many cities and ecosystems along the coast due to rising sea level and the severity of droughts. A national program has been launched to address several challenges that exist around the modelling, prediction, mitigation, and management of saltwater intrusions. This project addresses the fundamental understanding of the fluid dynamics phenomena related to the mitigation of saltwater intrusions and aims at optimizing such mitigation measures.

Project description
In this project, the PhD candidate will investigate how certain fluid dynamics phenomena
(e.g. localized turbulent mixing, breaking of internal waves, counter currents) can reduce the extent of saltwater intrusions. For this research, the PhD candidate will use large-eddy simulations resolving the relevant scales and laboratory experiments incorporating optical measurement techniques. The candidate will use knowledge gained to propose possible novel mitigations measures and improvements to existing ones.

This subproject will be carried out within the Fluids and Flows group at the Department of Applied Physics ( of Eindhoven University of Technology. The PhD candidate will be supervised by dr. M. Duran Matute and prof. H.J.H. Clercx, in collaboration with dr. R.J. Labeur (TU Delft). This project is part of the SALTISolutions Perspectief Program that encompasses several national and international partners.


  • We are looking for an enthusiastic PhD-student with a strong background in fluid dynamics, civil engineering or physical oceanography, and a strong affinity with both theoretical and numerical tools.
  • A master’s degree (or an equivalent university degree) in in (applied) physics, physical oceanography, applied mathematics or mechanical/civil engineering.
  • A research oriented attitude.
  • Ability to work in a team and <interested in collaborating with the industrial partners>.
  • Fluent in spoken and written English.


  • A meaningful job in a dynamic and ambitious university with the possibility to present your work at international conferences.
  • A full-time employment for four years, with an intermediate evaluation after one year.
  • To support you during your PhD and to prepare you for the rest of your career, you will have free access to a personal development program for PhD students (PROOF program).
  • A gross monthly salary and benefits in accordance with the Collective Labor Agreement for Dutch Universities.
  • Additionally, an annual holiday allowance of 8% of the yearly salary, plus a year-end allowance of 8.3% of the annual salary.
  • A broad package of fringe benefits, including an excellent technical infrastructure,
    moving expenses, and savings schemes.
  • Family-friendly initiatives are in place, such as an international spouse program, and excellent on-campus children day care and sports facilities.
