PhD position - Bedrock fracture network controls on alpine groundwater dynamics
Mountains are "water towers" - they sustain perennial water resources down-gradient during dry and warm periods. Groundwater plays a critical role within the mountain water cycle. In settings underlain by crystalline rocks, groundwater flow and storage are controlled by 3-dimensional networks of fractures. The lack of data in alpine contexts, combined with the complex processes shaping the architecture and hydraulic properties of the fractured bedrock, make their characterization challenging. Current methods for integrating heterogeneous subsurface properties into catchment- to regional-scale hydrological models generally involve extensive simplifications based solely on lithological constraints. This raises questions regarding the validity of this approach to quantify subsurface flow and transport processes.This PhD project will use a multi-faceted hydrogeophysical approach to understand and quantify the role of fractured bedrock on groundwater storage-discharge processes. The primary goal is the development of new methodological frameworks that enable parametrization of catchment-scale hydrological models with 3-D representations of hydrodynamic properties that properly capture the observed dynamics. Extensive field work is planned at established mountain hydrological observatories in the Swiss Alps where international institutions are collaborating.
The student will be responsible for the following tasks:
The PhD position is based at the Centre for Hydrogeology and Geothermics (CHYN) at the University of Neuchâtel under the supervision of Dr. C. Roques, Dr. Landon Halloran and Prof. B. Valley. The CHYN offers a stimulating research environment with about 50 collaborators. The candidate will benefit from a comprehensive pool of field and laboratory equipment, technical support staff, and a dynamic PhD school.
