AB: Ground water is not only a vital water resource but also a dynamic variable that may play an important role in the global water cycle and climate system. There has been an abundant of groundwater research and analyses at borehole, field, to local scales, but few at regional to large scales in which interactions between surface and groundwater and their impacts on water and energy budgets are explicitly investigated in a land-atmosphere coupling system. In this talk, a dynamic representation of groundwater table movement for unsteady state conditions and how the consideration of groundwater table fluctuations affecting water and energy budgets will be presented at watershed scales. Then, initial assessments of the role of surface and groundwater interactions on water and energy budgets at large spatial scales will be discussed through a series of sensitivity analyses based on the MM5-VIC land-atmosphere coupling system.
