Functieomschrijving

The aerobic and anaerobic microbial turnover of organic matter in surface waters affects the processes of flocculation, sedimentation and consolidation of suspended particulate matter (SPM), leading to the formation of layers of different rheological properties in the transition zone between the water phase and the genuine river bed. As a consequence, the detection of the nautical bottom in ports and waterways and the efficiency of maintenance dredging carried out to warrant the navigable depth can be impeded. Port authorities therefore seek new insights into the strength development of fluid mud and sediment layers and the impacting processes and parameters. The aim of the research is to elucidate the role of the physicochemical properties of the organic and mineral phases for organic matter degradability and to investigate their influence on the rheological properties of the corresponding fluid mud and sediment layers observed in situ. Research activities will include field sampling campaigns in the Port of Hamburg and subsequent laboratory analyses, addressing, amongst others, the following aspects: (1) characterisation of SPM and sediment properties and identification of properties relevant for the organic matter degradation, (2) quantification of the size of the degradable organic matter pools, and (3) temporal and spatial variability of all pertinent processes. All activities will start as soon as possible and be carried in close cooperation with Hamburg Port Authority, with the University of Hamburg and the Department of Hydraulic Engineering at the TU Delft.

Functie-eisen

Applicants should meet the following requirements:
• MSc degree in a discipline of the Biosciences, Earth Sciences, Geo-environmental Engineering (or comparable) with a focus relevant to the research field

• Strong analytical skills
• Ability to work independently and in a team
• Ability to cooperate with both scientific and industrial partners
• Ability to write and contribute to scientific publications and technical reports.
• Good proficiency in spoken and written English language, German language skills are desired.
