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
