POSITION OVERVIEW

The Department of Physical Geography at Utrecht University is seeking a highly motivated PhD candidate with a background in hydrology, earth system science, atmospheric science, agroecology, or related fields.

The successful candidate will work on the project:
“Physics-informed AI-modelling of land surface processes in a global hydrological model”, part of a large international initiative to improve the modelling of global water resources.

RESEARCH CONTEXT

Water resources are overexploited in many areas, leading to depletion and deterioration of aquifers, reservoirs, and rivers.
