A MODEL INTEGRATION FRAMEWORK FOR ASSESSING SURFACE AND SUBSURFACE WATER INTERACTION

Improve process model simulation at the WS• New research knowledge becomes available

• Finer spatio-temporal resolutions data• Feedback fluxes

• Long-term impacts assessments• Future scenarios• Agro-ecosystem interactions

• Decrease uncertainty in model outputs

• Distributed ET fluxes

• Distributed percolation fluxes

• Distributed groundwater feedback fluxes

• Surface-groundwater interaction

Atmospheric-surface-subsurface hydrologic linkage• Hydrologic cycle is a complex system• Essential to account for in water budgets
