The interaction of groundwater dynamics, overland flow, and land-surface processes has gained recent attention in hydrologic sciences. Over the past several years, owing also to updated numerical and computational technologies, new approaches for modeling these coupled interactions have been developed. Research is addressing these issues from a range of scales and process descriptions. The goals of this session are to discuss these new techniques and to understand the feedbacks of these coupled processes across the hydrologic cycle. Contributions are invited on theoretical, numerical, and experimental studies that address all components of the water and energy cycles in an integrated fashion over a wide range of time scales (diurnal to decadal) and spatial scales (column to basin and global scales). Emphasis is placed on the coupling of the different processes of the surface-subsurface-land-surface system. Presentations are encouraged on techniques for modeling and predicting groundwater storage and fluxes on multiple scales, links to climate and global water cycle variability, groundwater remote sensing, and prospects for extending the value of existing knowledge and observational records across scales. Specific subtopics of interest include watershed dynamics, feedbacks on evapotranspiration, thermodynamics of soil moisture, infiltration and runoff, and interactions with atmospheric and precipitation processes, among others.
