Session Description The global water cycle has been profoundly affected and intensified by climate change and human intervention over the last decades, and this trend is projected to be accelerated in the future. Large-scale hydrological observation and modeling tools are essential for the study of the changing nature of the water cycle and for accurate assessment and future projection of water resources. Large-scale data are increasingly becoming available to scientific communities from remote sensing or reanalysis products. While large-scale hydrological models have been advanced through intensive improvements in schemes representing soil and vegetation processes over the past few decades, the hydrologic community still lacks holistic and integrated models that couple the natural water cycle with human systems. This session is intended to provide a collective view on (a) recent improvements in land surface modeling and global hydrological models including human systems (e.g., irrigation, flow regulation, groundwater pumping), (b) surface water-groundwater modeling at global continental, to regional scales, (c) integration of remote sensing data on the water cycle (e.g., GRACE, GPM, MODIS, AMSR-E, SMOS, and SMAP) into hydrologic models, and (d) application of integrated hydrologic models to address water and agricultural sustainability issues. Abstracts addressing the coupled nature of the water cycle and human activities using large-scale data and from modeling perspectives are particularly encouraged, but regional- or global-scale studies related to depletion of surface water and groundwater resources, climate change, and water resources sustainability are also welcome.
