About the position

We offer an exciting 3-year PhD position based at NTNU's Department of Civil and Environmental Engineering as part of the NTNU Ocean and Coast funded project "The PLUME". The position belongs to work package WP1 Water Dynamics, which aims to build an integrated modelling platform for freshwater flow, river discharge, and plume dynemics from the full catchment of the Trondheim Fjord to the fjord itself. The main supervisor is Professor Hans Bihs, Department of Civil and Environmental Engineering. The position will work closely with Professor Knut Tore Alfredsen, Professor Mats Ehrnström, and Postdoctoral Researcher Adrian Kirkeby. The research connects directly to the ERC Consolidator Grant PARTRES and the NFR large-scale project IMod.

The new integrated modelling approach for freshwater flow, river discharge, and plume dynamics will be built around the open-source hydrodynamics framework REEF3D. The model is developed in-house and the candidate will be a member of the research team. REEF3D::NHFLOW resolves circulation, mixing, and exchange over sills and basins. It is used to produce a highly detailed picture of the plume dynamics, including spreading, dispersion and vertical exchange. Macro precipitation–runoff models are used to estimate time-resolved freshwater inflows from the entire fjord catchment, including the effects of hydropower, regulation and projected climate driven changes in rainfall and seasonality.

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

Your immediate leader will be a professor.

About the project

The PLUME is an interdisciplinary project funded by NTNU Ocean and Coast, with the goal of understanding the Trondheim Fjord as a connected system - from river catchment to open water, from physical dynamics to public knowledge and governance. It brings together researchers from mathematics, civil engineering, biology, industrial ecology, and science and technology studies, hosted by the research team Water and Water Systems. The project runs from mid-2026 to mid-2029 across three interconnected work packages: WP1 Water Dynamics, WP2 Nutrient Impacts, and WP3 Societal Interactions. It is led by Mats Ehrnström (leader) and Terje Finstad (co-leader). Each position is central to one work package and will collaborate closely with the others.

Duties of the position

Complete the doctoral education until obtaining a doctorate
Carry out research of excellent scientific quality
Academic publications and popular science dissemination
Contribute to joint activities across The PLUME
Collaborate with the PARTRES and IMod project teams at NTNU
