Scope (Session Description) Confounding impacts of anthropogenic interventions and natural climate variability have altered the mean state, variance, and tradeoff in the terrestrial hydrological cycle and its constituent water storage and flux components, with continually growing magnitude and uncertainty in the Anthropocene. In the premise of 1) the tendency of studies focusing on one component (of water storage, e.g., surface water, soil moisture, groundwater; or of fluxes, e.g., precipitation, evaporation runoff) as a standalone, and 2) inherent limitations of the traditional methods for mapping these variables, here, we invite studies leveraging a multitude of state-of-the-art methods based on modeling, reanalysis, remote sensing, and machine learning. Synergistic assessment of multiple fluxes/components will be instrumental in the hydrological process understanding and effectively managing water resources for a sustainable society. The scope of this session is to discuss recent scientific results related to, but not limited to: 1) Proof-of-principle and proof-of-concept studies dealing with surface water- groundwater interaction. 2) Understanding the impact of global warming and anthropogenic activities (e.g., urbanization, water diversion projects) on surface water, soil moisture, and groundwater at various spatial (e.g., urban, basin, nation) and temporal (from sub-hourly to decadal) scales. 3) Quantifying trends and variability in dwindling quantity and deteriorating quality of various (sub)surface resources and their management in a warming climate. 4) Improved methods (e.g., artificial intelligence) for assessing past and projected (e.g., until the year 2100) hydrological cycle changes and related hydroclimate extremes (floods, droughts), compound events, and their transition and propagation behaviors.
