I am modeling microbial mediated reactions and the environmental factors affecting biogeochemical dynamics in the subsurface at the small scale (sub-meter). This knowledge can be applied at the catchment scale by using appropriate upscaling methodologies and coupling the up-scaled biogeochemical model with robust surface water and groundwater flow models. I shall employ this flow and reactive transport model to predict solute discharge in the catchment. This project contributes substantially to identification of environmental drivers and relevant parameters influencing biogeochemical dynamics in the critical zone. This will result in focused parameterization of models in regions where one might not have access to resources to conduct detailed studies using state-of-the-art equipment.
