Modelling microbial processes at material interfaces in the deep subsurface

The aim of this project is to numerically model microbial activity at interfaces between different materials in the deep subsurface. Since such interfaces usually connect two regions with very different hydraulic and mineral properties, the resulting flow patterns, the prevailing transport mechanisms or the distribution of chemical species can have far-reaching consequences for microbial activity. Using two examples – one natural and one technical – numerical models will be used to determine the prerequisites and relevant mechanisms of the microbial processes under consideration. Numerical simulations atthe millimetre scale (with pore-network models) and at the metre scale will be carried out for both examples. The numerical models required for further research will be developed and tested as part of the IFF project.
