The project “Comprehensive Observations of Episodic Basal, Englacial and Lateral Influences on Ice Stream Dynamics” (COEBELI) is a collaborative effort of several research institutions to understand the mechanisms leading to rapid ice flow of outlet glaciers of the Greenland ice sheet. The project uses a combination of field observations (dynamics, seismicity), remote-sensing products, and state-of-the-art numerical models to investigate non-continuous processes leading to fast ice flow.
Within the project, the Material Point Method (MPM) will be used to model detailed high-rate processes such as glacier calving and tsunami wave generation, episodic crevassing in the ice stream margins, and basal fracturing processes leading to seismic emissions.
The successful candidate will interpret field data from Jakobshavn Isbrae (Greenland) with model results to obtain relevant model parameters, and to investigate the physical processes. A close collaboration with PhD students is envisioned. The post-doc will be supervised by Dr. Martin Lüthi (UZH) and Dr. Johan Gaume (EPFL).
Candidates should hold a PhD in (computational) mechanics or in (computational) geosciences. Back-ground/experience in solid and/or fluid mechanics and numerical modeling is mandatory. Additional qualifications such as experience with the Material Point Method or with glacier calving processes are an advantage. The candidate should have very good English skills and is expected to be a team player with excellent communication capabilities as she/he will collaborate with students and PhDs involved in the project.
UZH and EPFL foster equal opportunities and are family friendly employers who value diversity and strive to increase the number of women scientists.
January 1st or upon agreement.
Please submit your application before 17 December 2021 including a letter of application briefly indicating your research plans as well as names and contact details of two possible referees, your curriculum vitae, a copy of your PhD diploma and a writing sample (your PhD thesis or relevant publications) in pdf-form.

TU Delft is seeking a motivated postdoc candidate to work on a collaborative research programme related to land subsidence. The overall aim of this programme is to develop an integrative approach to achieve feasible, legitimate and sustainable solutions for managing the negative societal effects of land subsidence. The programme connects fundamental research on subsidence processes to socio-economic impacts of subsidence and to governance and legal framework design. The postdoc will identify potential measures in areas prone to subsidence focuses on the technical implementation of these measures and determines their impact on the environment and society. The post doc researches the interaction of different measures in the urban area and/or on the impact of measures beneficial for the rural area.

Project Title
THCM characterisation of engineered bentonite barriers in the very near field behaviour in deep geological repositories of high-level radioactive waste
Project description
The retention properties, the low permeability and the swelling capacity of compacted bentonites have led to an interest in their use in various fields of technology. This is particularly true in the design of deep geological repositories for spent nuclear fuel and other high-level nuclear waste. The objective of the project is to develop a coupled THCM formulation, with non-simplistic geochemistry and consideration of thermal effects at high temperatures that includes the thermodynamics of bentonite hydration. The mathematical formulation will be implemented in a numerical tool to simulate the behaviour of bentonite barriers at repository scale. This will be especially useful for the study of the repository in the short term, when, in unsaturated conditions, temperatures in the engineering barriers are expected to be the highest. As a result, the characterisation of critical phenomena for the safety of the repository (maximum temperatures, corrosion, dissolution) will be improved, highlighting the scope and limitations of the formulations used to date.
As a starting point, a base model in Comsol Multiphysics integrating coupled THM and THC developments will be used.
Conditions
A 4 year FPI grant by the Spanish Ministry of Science and Innovation is available to support the candidate. The collaboration will start as soon as the administrative procedure is solved, expected to be in the first quarter of 2022. The terms and conditions for submitting applications can be found at :

Energy geostructures are geotechnical structures also used to exchange heat with the ground for heating and cooling of adjacent buildings, using a heat pump. The first application was that of energy piles, nowadays largely used in several countries. More recently, the technology has also been developed for infrastructures like metro stations and tunnels, underground parking and cut-and-cover tunnel, slabs. The significant advancements in the research on this topic are such that we are now ready for testing and implementation in our cities.
This project is a unique opportunity to monitor and investigate the behaviour of a real scale energy infrastructure. The work is based on the existing case study of a metro station, already constructed and fully equipped with ground heat exchangers in the diaphragm walls and slabs.
In the framework of this project, the structures, the air and the surrounding soil of the studied metro station will be instrumented with sensors and monitored during operational in real environmental conditions.
The role of the post-doc will be to develop a coupled thermo-hydraulic model of the metro station accounting for the real complex hydrogeological context, predict the response of the station in terms of heat exchange potential and temperature field under different scenarios, analyse the monitoring data and compare with the numerical results. The most affecting parameters will be also identified. Possibly, the behaviour of the geostructures from the geotechnical and mechanical point of view will also be investigated.
We are looking for a candidate with a good knowledge on soil and concrete thermal behaviour, hydrogeology, thermo-hydraulic couplings in porous media, numerical modelling with FEM, soil mechanics, thermo-mechanical couplings. Experience with the software COMSOL Multi-physics will be positively evaluated.

Project description
This project goal is to develop and test a realistic modelling platform to represent the dynamic interaction during installation of monopiles in soils. Coupled hydro-mechanical behaviour will be considered for the soil, allowing for drained, undrained or partly drained installation. Representation of the monopile will aim to reproduce the dynamic driving signals recorded at installation. Being able to correctly reproduce installation will open new fundamental perspectives into monopile design for both lateral and axial loading. Model development will be based on the Geotechnical Particle Finite Element method (GPFEM) that has proven its ability to tackle quasi-static and dynamic coupled problems involving large deformations.
Conditions
A 4 year FPI grant by the Spanish Ministry of Science is available to support the candidate. The expected starting date is around June 2022, by which time the candidate should have a MSc degree on Civil Engineering, Geotechnical Engineering or a related field. Interested candidates should send a CV to Prof. Marcos Arroyo (marcos.arroyo@upc.edu) or Mr Jon Rodríguez at fellowships@cimne.upc.edu before the 5th of November 2021.
