Are you a modeller of water quality and ecological processes in marine and estuarine systems? Do you enjoy working with numbers and take pride in doing a good job and avoiding mistakes? Our Environmental Hydrodynamics and Forecasting department is looking for a talented modeller to supplement our team of water quality and ecology experts in marine and coastal ecosystems!

What can you expect as a Marine Water Quality & Ecology Modeller?

In our work on national and international projects, more and more use is being made of coupled physical- biogeochemical-ecological models, as well as habitat-oriented models to provide insight into interactions between human activities and the ecosystem. We undertake a wide range of applied research and specialist consultancy projects in marine and estuarine environments related to water quality assessments and ecological impacts. Our projects are challenging and interdisciplinary. They integrate knowledge of physical processes with water quality/chemistry and ecology, to guarantee safe and sustainable water systems.

Your main activities are to:

  • Use, develop and validate numerical models of water quality processes (e.g. oxygen, nutrients, primary and secondary production) in marine and estuarine systems;
  • Undertake research and specialist consultancy tasks as a member of a team including analysis of modelling outcomes, comparisons with measurements, etc.;
  • Assist in writing reports and preparing presentations for clients;
  • Assist in project definition and acquisition;
  • Actively increase the network and cooperation of the department with other groups inside and outside of Deltares.

What does Deltares expect from you as a Marine Water Quality & Ecology Modeller?

  • University education (at least M.Sc. level) with a background in natural sciences or closely related field of study;
  • You have sound understanding of the functioning of marine ecosystems, including water chemistry processes;
  • You have a basic understanding of other fields of knowledge that relate to marine and coastal systems and are a quick learner;
  • You are an excellent team player and can build interdisciplinary collaborations;
  • You are an entrepreneur and a good networker, you have a pro-active approach towards the market, and you appreciate a challenge;
  • Good command of English in word and writing. Good command of the Dutch language is an advantage.

Additional desirable skills

  • Knowledge of and/or affinity with one or more of the following skills would be an advantage:
  • Ecological processes from primary production to higher trophic levels;
  • Experience with Dynamic Energy Budget (DEB) modelling;
  • Experience with scripting languages such as R, Python, Matlab, etc;
  • Experience with numerical computational methods;
  • Some hands-on experience with the use of modelling systems for water quality and ecology in marine and estuarine environments.
