Evapotranspiration (ET) and infiltration are critical fluxes affecting hydrologicalcycles of land process. The ET furthermore links energy exchange between land andatmosphere. Variations of both fluxes are controlled by micrometeorology, surfacecondition, and hydrogeology. Groundwater is the most important water resources inaddition to surface water. Except human pumping, although groundwater budget isconceptually dominated by ET and infiltration by root uptaking and downwardmoving of soil water, there is a critical knowledge gap on how these near‐surfacefluxes facilitate variations of groundwater levels. Interestingly, how fast or delayedresponses of groundwater levels to these fluxes during event or seasonal scales andtheir interconnected mechanisms are furthermore complicated. This study proposedintegrated hydrometeorology experimental measurements and land surface processmodel developments. On the experimental setup, capacity of subsurface hydrologicalmeasurement will be deployed to integrated current micrometeorology instrumentsat the National Central University site. On the modeling aspect, land surface processmodel will be integrated into variable‐saturated subsurface model to providecapabilities of investigating nexus of micrometeorology factors, unsaturated zone,and groundwater with coupling simulations. The research will provide contributionsto understand dynamic nexus of ET, infiltration, and groundwater from event toseasonal scales. Novel scientific knowledge and solution tools of handlinginteractions among atmospheric water, surface water, soil water, and groundwaterwill be delivered to facilitate simulations of land surface process and watershedhydrology.
