ER2: Integrated modeling for up-scaling bio-reactivity at interface hotspots
Research Fellow: Karlie McDonald, University of Birmingham (UK)
ER2 will develop new modelling approaches to integrate the effects of local hotspots on biogeochemical transformations and fluxes at the scale of small catchments, the spatial units at which management decisions are made.
Tasks and methodology
Numerical flow and reactive transport codes such as HydroGeoSphere, PHT3D and complex CFD-Codes will be used to systematically explore integral interface functioning with respect to matter transformations. The models will utilize the new generation of distributed data generated within WP1 to apply innovative stochastic model parameterisations and scenarios (together with IGB+UFZ, ESR1, 3). Up-scaling to the catchment scale will be accomplished in a nested modelling framework applied to two field settings with nested catchments: i) the CNRS sites (ESR 11, ER1, Joint Field Experiment) and ii) the Willamette Critical Zone Observatory (WCZO) of the associated partner OSU. The developed expertise and modelling concepts will further be utilized to evaluate integral effects of biogeochemical hotspot activity at marine-sediment interfaces based on the extensive dataset derived in ERS 6 (NIB) and ER3 (BioSistemika).
