GEWaSC Multi-Scale Simulation Framework Concepts and Structure
GEWaSC will mechanistically predict biogeochemical system functioning at the watershed scale by (a) representing hydrological and biogeochemical connectivity across space and time scales in a matter that honors system variability and (b) coupling terrestrial subsurface microbial composition, activity and adaptation to biogeochemical processes.
- Surface and subsurface hydrology provides the basis for model discretization because of their control connectivity.
- Computation challenge - to resolve spatial variability of surface and subsurface features including interfaces (surface-subsurface) while honoring complex biogeochemical networks mediated by emergent microbial guilds.
- Simulation framework based on a hierarchical approach to multiscale modeling that involves definition of relative macroscale and microscale system components.
- Space/time coupling of defined microscale/macroscale components dictates approach used.
- Open source and modular components.
