The numerical modeling of chemical processes with fluid and mass transport is increasingly used in different fields of geosciences, e.g. soil science, groundwater remediation, acid mine drainage, geothermal energy, CO2 storage and storage of radioactive and chemotoxic waste.
The session would like to present the current state of coupled reactive models, to identify future trends and to foster the discussion between code developers and users from the different fields of applications.

We welcome contributions presenting results from national and international R&D projects, experimental and modeling studies, and applications from performance assessments.
We especially encourage contributions related to:
* Fundamental investigations of physical and chemical processes related to transport and their interactions (couplings).
* The linking of relevant processes at different space and time scales (e.g.
lab, field and repository scales).
* New numerical approaches for coupled reactive codes, especially for high performance computing (HPC).
* The use of laboratory and field experiments for benchmarking numerical codes.
