Deltas represent the transfer zone where sediment is moved from terrestrial to the subaquatic domain. The sediments are deposited in the deltaic areas and then remobilized again through eroding underflows or delta lip failures. In the past, tsunamogenic delta failures have occurred in Swiss lakes. Due to continuous sediment supply from the incoming river, however, the traces of such failures are missing. Thus, the origin, failure processes, and flow mechanisms remain unknown, but are needed for hazard assessment. In this project, the goal is to better understand the processes related to delta failures in lakes, through a multi-approach monitoring (ocean bottom seismometer, bathymetric mapping, water flow velocity measurements and sediment analysis).
Tasks will be to study the subsurface structure of the deltaic slope, identify the potential mobile sediment thickness, the variability of sediment structures, assess the site response based on ocean bottom seismometer data & explore the feasibility of using ocean bottom seismometer (OBS) data to identify and monitor failures and sediment remobilization in deltas
We are interested in candidates with a doctorate in Earth Sciences. The candidate should be interested and enthusiastic to conduct research with a combination of field work, innovate data analysis, and computational methods. Ideally, the candidate should have experience with processing, analyzing, and interpreting geophysical data (experience with ocean bottom seismometer data is desirable), handling geophysical instrumentation, and programming. The candidate should be willing to conduct (limno)geological field work and have a flair for geophysical methods in aquatic environments, for limnogeology and sedimentology. It is expected that the candidate is committed, able to work independently and in a structured manner, willing to collaborate with other institutes and University-wide national and international collaborators, be creative, communicate, think critically, and share skills and results. Good English communication skills are required, basic German is an advantage.
We offer a Postdoc position for two years. The candidate will work on ambitious and varied tasks in a dynamic and international research environment and will use the state-of-the-art equipment.This work will be done in strong collaboration with the Engineering Seismology Group of the Swiss Seismological Service at ETH Zurich. The project offers an opportunity to transfer knowledge and skills between disciplines. It is also possible to arrange flexible working conditions (e.g., part-time home office).
