PhD student (m/f/d) on inter-basin exchanges physical processes in lakes

Eawag, the Swiss Federal Institute of Aquatic Science and Technology, is an internationally networked aquatic research institute within the ETH Domain (Swiss Federal Institutes of Technology). Eawag conducts research, education and expert consulting to achieve the dual goals of meeting direct human needs for water and maintaining the function and integrity of aquatic ecosystems.

The Department of Surface Waters – Research and Management (SURF) located in Kastanienbaum (Lucerne) has a vacancy for a

This research opportunity is an integral part of an exciting SNSF funded project aimed at advancing our understanding of lake dynamics and their ecological implications. Lakes have traditionally been analyzed using a one- dimensional vertical framework due to seasonal density stratification, but this approach is challenged by observations of lateral density-driven flows. These flows, particularly prevalent in multi-basin lakes, contribute to heat budgets, deep water oxygenation, and fine-scale vertical structures. Despite their importance, little has been quantified about their basin-scale relevance, a pressing issue given the documented reduction of winter mixing depth due to climate changes. This study aims to address such research gaps by integrating high-tech in-situ experiments with modeling techniques, focusing on understanding interbasin exchange rates, associated turbulent mixing, and the impact of winter exchanges on deep-water formation and ventilation. The multi-basin Lake Lucerne and Lake Zug are proposed as ideal natural laboratories for this project.

We are seeking highly motivated candidates who have earned a master's degree in a relevant field, such as physics, physical oceanography, mechanical engineering, environmental science, applied mathematics, or computer science. An interdisciplinary mindset is crucial, as we encourage collaboration across various disciplines (Prof. Hugo Ulloa, University of Pennsylvania, Prof. Rolf Kipfer, Eawag, Dr. Dave Janssen, Eawag). Strong English communication skills and the ability to work effectively in teams are essential qualities we are looking for. This position will be located within the SURF Department in the Aquatic Physics group led by Damien Bouffard at Eawag Kastanienbaum (Luzern).

Application must be submitted by 1st January 2025 and should include an application letter describing your interests and their relevance to this position, a CV, link to own git repository (if existing) and the names and contact information for two references. The anticipated starting date for the position is April 2025 or on agreement.
