This project aims at investigating oxygen and
carbon dioxide fluxes between the atmosphere and groundwater. The project can
be performed either in the laboratory or based on numerical modeling. In the
laboratory high-resolution flow-through experiments, using innovative sensor
technology, will be conducted to quantify the dynamics of O2 and CO2
interchange under transient heat boundary conditions and varying wind speed at
porous media surface and to investigate the role of microbial activity on the
interchange of O2 and CO2. Alternatively, the focus can
be on the development of fully coupled numerical modeling approaches to
quantify the dynamics of gas interchange. This master thesis will be within the
framework of the DFF-funded project GIGA starting in Fall 2017.
The ideal candidate should be interested in groundwater quality and solute transport in porous media. Previous laboratory or modeling experience is an advantage.
