at the Department of Physical Geography . Closing date: 6 October 2022.

The Department of Physical Geography is one of the major departments within the Faculty of Science. The department has approximately 110 employees and educates approximately 1 000 students annually. Education is oriented towards geography, geosciences, biology-earth sciences, and environmental protection and management. The main research areas are: Landscape, Environment and Geomatics, Climate Science and Quaternary Geology, Geomorphology and Glaciology, and Water, Permafrost and Environmental systems. We offer a stimulating and friendly environment in a very diverse and international department.

Project description The doctoral research will be conducted within the framework of a project on modelling coupled hydromechanical analysis of rock stress, permeability and transmissivity changes caused by tunnel excavation in heterogeneous discrete fracture networks for quantification of groundwater leakage. Groundwater flow in crystalline rock occurs through fractures and deformation zones. Understanding these flows and how they change subject to excavation is important for assessing environmental impacts. This project will study changes in the stress field in the excavation disturbed zone and how that impacts fracture aperture and permeability as well as the effects it has on groundwater flow in the surrounding rock. Specifically, the focus is on adopting numerical discrete fracture network models for hydromechanical coupling at multple scales from single fractures to complex networks, and linking model analysis with lab and field data.

Qualification requirements In order to meet the general entry requirements , the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

In order to meet the specific entry requirements , and to fulfil the general syllabus for doctoral studies in the field of physical geography, the candidate for this position should have acquired a total of 240 higher education credits (of which at least 60 at advanced level), or acquired in some alternative fashion, the equivalent knowledge in geoscience, environmental science or other relevant natural or engineering science. The qualification requirements must be met by the deadline for applications.

Selection The selection among eligible candidates will be based on their capacity to benefit from doctoral training. The following criteria will be used to assess this capacity: The candidates' documented knowledge of research in the field of flow in rock fractures, numerical modelling of flow in rough-surfaced fractures, application of combined numerical and experimental methods, and geostatistical analysis of heterogeneous systems. Additional assessment criteria include written and oral proficiency in English, the capacity for analytical thinking, creativity, initiative, independence, and ability to collaborate. The assessment will be based on previous experience and grades, the quality of the degree project, experience in conducting and communicating research, references, interviews, and the candidate's written motivation for applying to the position.
